Differences Between Micheli, Massei, Hellmann and Nencini Courts Pointing To Almost Certain Outcome

Posted by Peter Quennell

What are the biggest differences? In fact the Supreme Court already pointed them out: science, scope, and balance.

Judge Micheli, Judge Massei and Judge Nencini all have a very extensive criminal-case background. All three have handled many cases of murder, many cases against the mafia, and many cases involving criminal science. All three have remarkable success records and have hardly ever been overturned on appeal. 

Judge Hellmann and his court are the extreme outliers. Until forced into early retirement by the Council of Magistrates, he had been a (quite good) business judge. His one major criminal case, years ago, had led to a farcical outcome, and he was ridiculed for this at the time.

Cassation made it very clear that he simply did not reflect a knowledge of the precise Italian law on scope and balance at the appeal level, and that he mishandled the science. In fact, as he actually said, the reason he appointed two independent DNA consultants was that he was at sea on the science.

That left Judge Hellmann’s panel of judges like a rudderless ship, bereft of the kind of good guidance from the lead judge on science, scope, and balance that comes only from many years of experience.

Which, given a level playing field, the pathbreaking Italian system enforces competently like almost no other.

Above all as the Hellmann Report makes extraordinarily plain, his court came to be swayed by the CSI Effect, with the help of two tainted consultants and probably the irresponsible Greg Hampikian in Idaho.

The CSI Effect is a phenomenon very, very unlikely to happen in Judge Nencini’s court.  First, take a look at this good explanation of what the CSI Effect is in the Fox Kansas City video.

Many crime shows such as the BBC mysteries and the Law & Order series and spinoffs show investigators solving their crimes in the old-fashioned way. Lots of witness interviews and alibi and database checking, and walking around and loose ends and lying awake at night puzzling. And often there’s a big stroke of luck. 

But if you watch the very popular CSI Las Vegas series and its spinoffs in Miami and New York, and the various clones on other networks, you will see something very different indeed.

When those shows first began airing worldwide in the late nineties, the producers explained that audiences increasingly appreciate learning something new when watching a show, and it is true, one sure can load up on the trivia.

But you will also see the US equivalent of Dr Stefanoni and her forensic team in those shows, roaming far beyond the narrow crime scene, interrogating witnesses and checking alibis and finding a lot of non-forensic evidence, and even at times drawing guns.

Most unreal is that, time and again, the forensic evidence testing is clearcut and takes just a few minutes and instantly clinches the case.

• There are several articles like this one and this one on whether the Casey Anthony jury was affected by a shortfall in the starkness of the forensics when the behavioral evidence seemed so strong.
• There are several articles like this one and this one on whether the appeal verdict outcome in Perugia might be affected in the same way.
• There are many articles like this one and this one and this one and especially this one saying there is a tough added burden on investigators and juries without a commensurate improved outcome.

With conviction rates declining in the US and Europe, professionals are taking a scientific look at whether the CSI Effect is one big cause of that decline.

At the macro level in the US this writer doubted that the CSI Effect is fatally unbalancing takes on the wider evidence. The same conclusion was reached in this first major study at the micro level.

But the belief in the CSI Effect continues. Articles like this one on an Australian site talk of a backlash against too many acquittals. Some articles like this one argue that maybe lay juries are out of their depths.

And judges and prosecutions are taking countermeasures.

In Ohio and many other states prosecutors and judges are acting against a possible CSI Effect in their selection and briefing of juries. And an NPR report came up with these findings.

Some states now allow lawyers to strike potential jurors based on their TV habits. Judges are issuing instructions that warn juries about expecting too much scientific evidence based on what they see on TV.

In the field, Shelton says death investigators sometimes run useless tests, just to show they went the extra CSI mile.

“They will perform scientific tests and present evidence of that to the jury. Even if the results don’t show guilt or innocence either way, just to show the jury that they did it.”

This is coming at a time when death investigators in America have no resources to spare. An investigation by NPR, PBS Frontline and ProPublica shows some states have already opted not to do autopsies on suicides, others don’t autopsy people who die in traffic accidents, and many don’t autopsy people who die over the age of 60.

But Murphy, the Clark County coroner, expects things to get worse.

“You know, we’re in budget cuts right now. Everybody’s in budget cuts. Las Vegas is no different than anybody else. We’re hurting. We’re going to feel that same crunch as everybody else,” he says.

One of Zuiker’s great disappointments is that, for all its popularity, his fictional Las Vegas crime lab didn’t generate more political support to fund death investigation.

“I’ve done my job. You know, we’ve launched three shows that cater to 73.8 million people a week and is a global phenomenon and the largest television franchise in history. We hoped that the show would raise awareness and get more funding into crime labs so people felt safe in their communities. And we’re still hoping that the government will catch up.”

None of the science in Meredith’s case has ever been discredited in court. Even in Judge Hellmann’s court the agenda-driven independent consultants Conti and Vecchiotti failed - and under cross-examination admitted it.

Also remember that the Hellmann court did not get to see two very key closed-court scientific presentations (the stark recreation of the attack on Meredith, in a day of testimony, and later in a 15 minute video) which had a very big balancing effect on the Massei court. 

Right now the reputation of not one defense-campaign stooge who has attacked the science remains intact.

Greg Hampikian has headed for cover. He had widely proclaimed that he clinched the Hellmann court’s outcome, in an act which may well have been illegal. Unsurprisingly, he is now trying very hard to hide his own claimed “proof ” of shortfalls in the science, as Andrea Vogt has been showing in her Boise State University investigation, and as we will soon post more on. 

Saul Kassin is another defense-campaign stooge who falsely claimed that he clinched the Hellmann court outcome by “proving” a false confession by Knox - in an interrogation that never even took place.

Despite all of this, maybe as straw-snatching, we can again see an organized attempt to confuse American opinion on the science of the case.

Whether she did this intentionally or not, that is what the PR tool Colleen Barry of the Associated Press was doing when she omitted that the trace of Meredith on the knife is undisputed hard evidence.

Judge Micheli and Judge Massei handled the science, scope, and balance with some brilliance. In all three dimensions Judge Hellmann fell short abysmally.

What is your own bet on the outcome under the exceptionally experienced Judge Nencini?

The Crime-Scene Clean-Up: How Rudy Guede’s Diary Provides Even More Proof That It Happened

Posted by pat az

This post is crossposted from my own place. Here is one of my previous crime scene analyses on TJMK.

Rudy Guede was ultimately declared convicted by the Supreme Court in 2010 of participating in the 2007 murder of Meredith Kercher.

The prosecution claims the two other participants are Amanda Knox and Raffaele Sollecito. Knox and Sollecito are currently appealing their conviction of the same crime.

The case against the three of them involves a suspected clean up of the hallway in the apartment after the crime. Meredith’s blood was found in the bathroom, and half a footprint in her blood was found on the bathroom mat. However, there was no visible blood between Meredith’s bedroom and the bathroom.

The only visible blood in the hallway were faint partial shoe prints that led directly out the front door of the apartment.

After the murder was discovered, the media reported almost daily on developments in the case. The day of the murder, the press reported on the blood found in the bathroom and the bedroom.

But until police used luminol at the apartment on December 18th, the media didn’t report on any significant blood found in the hallway.  Between November 2nd and December 18th, only one person stated that significant amounts of blood had been in the hallway.

Rudy Guede.

Rudy Guede actually wrote about it in his diary between Nov 20th and Dec 6th, after being captured in Germany.






The police arrived at the apartment on November 2nd. According to media reports, the blood they spotted immediately was only in the bathroom and Meredith’s bedroom.  When the scene was more closely examined, after the discovery of the body, police found visible blood patterns on the floor left by Guede’s left shoe as he left the apartment.

None of the people who arrived in the apartment on the afternoon of November 2nd reported seeing them; these footprints are not in any of the stories of the events of Nov 2nd told by Amanda Knox nor Raffaele Sollecito. So, while these prints were visible, they were not substantially obvious.

On December 18th 2007 investigators applied Luminol in the hallway and other bedrooms. This forensic chemical is used to detect blood which has been cleaned away. The Luminol revealed several footprints in the hallway between the bedrooms of Knox and Meredith. Example below. Some of these footprints were leading towards Meredith’s door.

They also discovered prints in Filomena’s room which contained Meredith’s DNA and Amanda Knox’s DNA. They also revealed a footprint in Amanda Knox’s bedroom. (The defense unsuccessfully contested the investigator’s conclusions that these prints were made with blood).

On November 19 2007, an international arrest warrant was issued for Rudy Guede. He was arrested in Germany on November 20th. Guede remained in Germany until his extradition on December 3rd.

During his stay in jail in Germany, Guede wrote a long statement that was published and translated. Guede’s writings are similar to to Knox’s jail writings in many ways - they both try to write out their own detailed version of events, while pointing blame elsewhere. 

But Guede’s comments may in fact be confirmation of a clean-up after the murder of Meredith Kercher (emphasis added):

I am asking myself how is it possible that Amanda could have slept in all that mess, and took a shower with all that blood in the bathroom and corridor? (Guede, Germany Diary, P21)

The police did not find evidence of any other blood until December 18th, AFTER Guede returned from Germany. As indicated above, the luminol revealed multiple footprints in the hallway, in Knox’s bedroom, and in Filomena’s bedroom. The image below shows these results in blue. Guede’s partial footprints are shown in red.






The conclusion is inescapable: Guede knew there would be significant evidence of blood in the hallway, before the police themselves found that evidence.

How did Guede know there would be more blood found in the hallway, before the police found that evidence on December 18th? And why wasn’t that blood there on the morning of November 2nd?

The courts believe the blood in the hallway was cleaned after the murder of Meredith Kercher. And the Micheli and Massei courts believed only one person had the motivation to hide this evidence: Amanda Knox.

Here is a summary of Judge Micheli’s October 2008 indictment finding.

In Judge Massei’s December 2009 trial finding for the original conviction of Knox and Sollecito, he also writes about the clean-up that the judges believed to have happened:

Further confirmation is constituted by the fact that, after Meredith’s murder, it is clear that some traces were definitely eliminated, a cleaning activity was certainly carried out. In fact, the bare foot which, stained with blood, left its footprint on the sky-blue mat in the bathroom, could only have reached that mat by taking steps which should have left other footprints on the floor, also marked out in blood just like (in fact, most likely, with even more [blood], since they were created before the footprint printed on the mat) the one found on the mat itself. Of such other very visible footprints of a bloody bare foot, on the contrary, there is no trace. (Massei, Dec 09; PMF translation)

In defense of Guede, Knox, and Sollecito, some might try to claim that Guede heard about blood in the hallway in the news. Rudy Guede was arrested 18 days following the murder of Meredith Kercher. During that time he had access to read the news and watch reports.

I have searched for articles in the period between November 2nd and December 18 which mention blood. All of the articles I have found so far discuss blood in the bedroom or the bathroom. One or two discuss footprints leading to the front door.

None of them discuss blood in the hallway that would justify a statement from Guede of “tutto quel sangue nel bagno e sul corridoghe” (all that blood in the bathroom and in the corridor)

Guede himself said he went between the bedroom and the bathroom, so may have tracked blood into the bathroom and therefore known blood would be found in the hallway.

Even that knowledge however confirms a clean-up, as there was not a trail of blood between the bathroom and Meredith’s room that justifies the footprint on the bathmat and blood found in the bathroom.

I have my own questions as a result of Guede’s knowledge of blood in the hallway:

Could the attack have started in the hallway? Could the first blood shed have been on the hallway tiles?

The prosecution and courts argue that Amanda Knox had a role in the attack and murder. Knox and her supporters are very adamant that there is no trace of Knox in Meredith’s bedroom. While the courts argue otherwise, could Knox’s role have been limited to the hallway?

Sadly, we may never know the full truth of what happened on the evening of November 1st, 2007.

Appeal Session #3: The Carabinieri Labs Report On The DNA On The Knife

Posted by Our Main Posters

[Above: an image of similar testing in the same Carabinieri laboratory in north Rome]

Final Update

So the court session does not even extend beyond the lunch hour. Good morning Seattle! At this moment it is still only 3:30 in the morning there. Only night owls will know what happened.

Yummi and Mason2 may have more for us, which will appear either here below this final update on in Comments.  Also Andrea Vogt and hopefully Barbie Nadeau will be filing longer reports in English. We will also check out all the Italian reporting.

Hard to see any game changers in today’s strong but undramatic testimony. The Carabinieri RIS DNA experts could not be shaken. All momentum remains with the prosecution and with the Supreme Court’s “givens” on the evidence, such as the presence of three attackers in Meredith’s room. 

The defenses seem to be giving up. They could have phoned it in. Sollecito lawyer Bongiorno didnt make any new fuss. And Amanda Knox lawyer Dalla Vedova was cut off by the lead judge several times, for trickily going off the point. He really is out of his depth in a criminal trial; at the same time often condescending.

And a seeming big slap in the face for the American defense stooge Greg Hampikian who seems to have illegally colluded with the disgraced Hellmann consultants Conti and Vecchiotti (who were not even mentioned today) when Judge Nencini asked Dr Barni “Would you be able to provide reliable standards without using suggestions from Americans?” Dr Barni responded “Of course”.

And Sollecito “wasted” his statement by whining about his life, showing no compassion for Meredith (despite his claimed visit to her grave), and not answering any of the dozens of open questions. Sollecito really needed to show he is both strong and compassionate and NOT a weakling under the thumb of Amanda - but he seems to have done quite the opposite. The family lawyer must not be too pleased.

Fifth Update

The opening of Frank Sforza’s trial in the same courthouse is postponed, apparently because new information on his campaign to poison opinion against the judiciary and his unsavory connections has been coming in.

Information will be exchanged that is gathered at this trial on mafiosos Luciano Aviello and at Aviello’s own trial for obstruction of justice which is now proceeding in the same Florence courthouse in parallel.

The findings and possible charges on the defamatory and dishonest books by Knox and Sollecito are due about now from the Florence and Bergamo prosecutors. Information gathered in those investigations could also be fed in to this process, or put aside for separate trials.

As both the AK and RS books are bulging with the standard PR talking points (some of which flowed from Frank Sforza and Doug Preston) in a sense it will be Curt Knox, the Mellases, Marriott, Sforza, Fischer and Moore who will be put under the microscope.

Fourth Update

A more detailed report on the DNA phase today from the Andrea Vogt website.

The RIS Wednesday deposited their forensic report on trace 36i, a spot of DNA identified (but not earlier tested) on the kitchen knife alleged to be the murder weapon. “Cento Percento” (100 percent) said Major Berti, discussing compatibility. The RIS found that the DNA was compatible with Amanda Knox, and excluded that it was that of Sollecito, Guede or Kercher. 

The RIS expert was asked only a few questions from attorneys and the judge. The judge asked why the RIS had done two amplications of the DNA and not 3 or 4. Major Berti described that two is considered the minimum number of amplifications necessary, according to today’s forensic standards, doing less (or more) might have diminished the reliability of the results. The judge also asked about the age of the equipment used. Berti responded that the forensic kit used this time has been commercialized since 2010 and available for use since 2011. 

At one point the judge stopped a line of questioning by Knox’s Rome attorney Carlo Dalla Vedova, who was asking why the RIS described Knox’s DNA as “fluids” when a prior expert had said the trace did not come from blood.  Nencini said: That question was not put to the RIS by this court, it was not their job to determine that. The other experts’ reports are in the case files for everyone to read, he noted, adding: “We cannot put words in the mouth of this expert that were said by another expert.”

Third Update

Tweets from our main poster Yummi (Machiavelli)

32. Judge Nencini’s comments were always addressed at Dalla Vedova’s arguments, who was in fact a bit silly

31. The Judge declared the evidence phase closed. Next court dates are 25 November for prosecution argument and 26 for the defences with 16 and 17 December.

30. Judge Nencini asked Dr Barni “would you be able to provide reliable standards without using suggestions from Americans?” Dr Barni: “of course”

29. Dalla Vedova said Tagliabracci was the only Italian source in the RIS report, all others are foreigners, emphasized the American labs…

28. Sollecito said his family absolutely never had issues with justice. And he is a proud ‘member’ of that family

27. He also played the ‘national’ card, as he remphasized ‘I am Italian’ twice and then addressed the court ‘I am an Italian, as you are’

26. Sollecito mentioned the defens’s arguments (he has an orthopedical issue with his foot etc.).

25. The questions of all parties to the experts were intended to elicit information to be used in arguing the unrelated previous finding

24. He mentioned Meredith’s name only once, to say he barely knew her.

23. Sollecito talked with a faint voice, a long speech in which he described himself as a victim.

22. The Carabinieri say that there are only a few governmental laboratories which have the 17025 certificate (the Carabinieri and the Police)

21. Nencini stops Dalla Vedova, points out that scientific community is international

20. Dalla Vedova tries to elicit that the good standards are not the Italian ones.

19. The RIS obtained the ISO9001 certificate in 2008, and a more specific certificate in 2012.

18. Bongiorno asks RIS to explain why two amplifications are recommended.

17. Prosecutor Crini asks if there are criteria to distinguish which labs or which experts are more competent.

16. Speaking about their software which allows to weight probabilities of attribution.

15. They note that three alleles which are ‘alien’ were drop off in one duplicate.

14. The biologic method has a ‘consensus’ interpretation and a ‘composite’ interpretation, two ways to interpret the double result.

13. They describe the methods employed, the ‘biologic’ method and the ‘statistic’ method.

12. Absence of any male trace stands out as a feature of the sample (all contributors are females)

11. They extracted two profiles in a duplicate in agreement with experts of all parties

10. Dr Berti says the sample was a low template. They have a strategy to obtain reliable results.

9. Points out that documentation says sample 36i comes from insertion of blade in the handle.

8. Dr. Berti summarizes the recovery of sample in Vecchiotti’s lab.

7. Bongiorno says Sollecito intends to release a spontaneous declaration. He will do that after the experts testimony.

6. Berti and Barni enter the court.

5. Many law students from the Florence school for Magistrates are in court to follow the hearing.

4. Sollecito had managed to enter the courtroom from side entrance eluding photographers. Carlo Torre arrives in court.

3. Giulia Bongiorno & Raff kiss each other. Giulia, Raff & Father have a worried discussion

2. I wonder… will the court withdraw his passport?

1. Raffaele Sollecito is in courtroom. Walking in empty room, few people waiting. Hearing will start 1/2h probably

Second Update

Tweets from Patricia Thomas (AP) and Sabina Castelfranco (AP)

Patricia Thomas “@MozzarellaMamma:  RaffaeleSollecito - Amanda Knox and I were very carefree and isolated in our love nest.

Sabina Castelfranco “@SCastelfranco:  Sollecito says he is not the assassin he has been described as. Says Amanda was his first love

2. RIS expert: explains technical details of testing DNA, how much is needed, how it is tested

1. Judge says he wants to hear from RIS experts first and then sollecito can give his declaration

Initial Post

Well, that first shot from the court at the top sure is a surprise, and maybe bad news for Amanda Knox. Where are Sollecito’s other lawyers, Bongiorno and Maori? Presumably they are off to the side talking. .

In tweets Andrea Vogt has mentioned that she is reporting for the BBC and the Associated Press TV; reporters cannot have bigger clients or more global reach than with those two. This is from Andrea Vogt’s website.

Court is now in session. Day will begin with RIS forensic debates. Raffaele Sollecito will make a statement later in the day.

Sollecito arrived in the Florence court of appeals looking relaxed and ready to make his case before the court later in the day. His father, Francesco Sollecito, also appeared visibly happy to have his son back in arms reach, after an extended stay in the Caribbean. A large number of his friends were in the audience.

Forensic experts for the defense Walter Patumi, Carlo Torre and Sarah Gino were also in attendance in preparation for debate on the new DNA evidence tested by the RIS in Rome, specifically, trace 36i on the kitchen knife alleged to be the murder weapon. RIS say the DNA profile is that of Amanda Knox. Arguments today will mostly about how it might have gotten there, with prosecutors attempting to place it in the context of the murder and defense attorneys arguing it could have been transferred during normal domestic use of the utensil.

Next hearings are Nov. 25-26, with a verdict expected in mid-December.

Appeal Court Sessions This Wednesday And Thursday Dont Look Very Promising For The Defenses

Posted by Peter Quennell

Expected proceedings and backdrop

The Carabinieri DNA report will be the main item and after an interruption from Sollecito we could see the final summations begin.

It is hard to believe that Doug Preston and other deniers of the plain facts have exulted in recent months that the Florence prosecution and court could be a big plus for the perps in their appeal. Presumably their joy was based on highly out-of-date takes on the 2010 move against Dr Mignini by a rogue Florence prosecutor in front of a rogue Florence judge.

Well, guess what? Both have been edged aside (like Hellmann and Zanetti), and the Florence Appeal Court and the Supreme Court have scathingly reversed Dr Mignini’s (and Dr Giuttari’s) faux conviction. And despite some ill-advised smearing still emanating from the Fischers, Moores, and other Knox parasites, Dr Mignini and his colleagues are seeing their careers and popularity (and 2009 success) riding very high. 

Judge Nencini and Prosecutor Crini are both hardened anti-Mafia battlers, and the not-so-hidden hand of the mafia in the Italian media campaign to poison public opinion against the court will not have escaped their attention for sure.

At least half a dozen of the parties on the defense bandwagon are known fellow-travelers of the mafia, and at least two are already headed for court - Luciano Aviello is already there for obstruction of justice, and Mario Spezi is headed there soon for a false and very elaborate framing of murder, a charge which could put him (and maybe Preston) away for a long while. The editor of Amanda Knox’s favorite mouthpiece, Oggi, is another we may see.

The same Florence prosecutors and courts will also be putting Frank Sforza on trial starting this wednesday with a preliminary hearing at which the details of the charges against him will enter the public domain. We will post then at more length. Our past commentary on Sforrza can be read here.

Frank Sforza has been a very close ally of some of the more hotheaded and misleading Amanda Knox supporters (both the Mellases, Steve Moore, Bruce Fischer, Michael Heavey, among others) and if he squeals to keep himself safe and out of jail, their own legal fortunes could take a big fall.

Frank Sforza is also required to appear for trial both in Perugia and Seattle, in both jurisdictions for physical abuse. If he fails to show in Florence (his Rome address is quite well known) we expect to see him nabbed by the police and sent on his way in handcuffs to all three trials. 

The same Florence prosecutors and courts are also contemplating new charges against Raffaele Sollecito and his publishing and PR bandwagon for the wild claims in his book, which were designed to poison public opinion agains the court and make him a ton of money. Those claims are a real minefield for Sollecito when he gets up and talks as they conflict both with what his team has said in court and what Knox said in her book.

Knox’s book, which was also designed to poison public opinion against the court and make her a ton of money, is being investigated by the chief prosecutor in Bergamo up north. At a minimum, the Florence prosecutors and judges will already know of this attack on the chief prosecutor which seems enough for a guilty verdict all by itself.

Contexting the DNA report

The main findings of the Carabinieri labs were summarised in the post directly below.

This further take on the context, and on who is up and who is down, was kindly contributed by one of our Italian court-watchers, who has many connections in Florence and Rome, and who sees the prosecution DNA teams as riding high now, and the defense forces and Vecchiotti and Conti as left with with no place to hide.

Dr. Barni and Dr. Berti, the two court-appointed Carabinieri RIS experts, are the authors of various internationally-circulated articles about presumptive blood tests, where they prove the opposite of some of the things the Sollecito—Knox sycophants deny. For example that bleach does decompose quickly when exposed to air and does not react to luminol after some 1-2 days.

Patrizia Stefanoni also has respected publications as a scientific author. In fact, in 2011 she was in the top 25 hits of forensic science with her publications, she has been even in first place  with this report.

The Carabinieri RIS note that the refrigerator has no temperature log; from this detail, albeit small within the overall report, we can deduce that Vecchiotti’s laboratory cannot have had ISO 9001 certification or any other international certification, given that the standards would require a temperature log.  Apparently the refrigerator doesn’t have an accurate thermometer either,  since the Carabinieri measured the temperature using one of their own.

Another detail noted at the beginning is this: the Carabinieri RIS expected the sample volume to be 24 microliters, since this was the remaining volume declared by Conti and Vecchiotti,  while Barni and Berti found it to be only between 16 and 17 microliters.  They infer that Vecchiotti and Conti might have been inaccurate on the estimation of the remaining amount after quantization, or hypothesize that the content might have evaporated over the last two years because the samples were not wrapped inside a protective film.

Vecchiotti and Conti had been already discredited, and have no credibility in the present appeal trial. However, the RIS finding might deliver a further blow to whatever might be their residual credibility. They had already previously been completely discredited because: 

1. They were appointed by judges who are now completely discredited, whose conduct was found illegitimate for reasons of unprecedented gravity, and who received a devastating bashing from the Supreme Court;

2. Vecchiotti and Conti were also discredited by Prosecutor Manuela Comodi in her court cross-eamaination in 2011, as the speciousness and falsehood of their arguments was exposed (this was the famous hearing where they claimed contamination on the ground that “everything is possible” and where Vecchiotti admitted she didn’t request negative controls)

3. Vecchiotti and Conti were discredited scientifically by Novelli’s argument, as he explained that they should have tested the 36-I sample, and as he also explained that that he found no trace of contamination in the Scientific Police laboratory’s work, or any reason to suspect contamination of Meredith Kercher’s DNA, and he explained that attribution could be done accurately based on bio-statistical calculation without requiring a second confirmatory test.

4. Finally, Vecchiotti and Conti were egregiously discredited by the Supreme Court which addressed a manifest issue in their “intellectual honesty”. Here is the Supreme Court ruling, page 65:  ” ... a member of the panel of experts could not assume any responsibility for unilaterally narrowing the scope of the mission, which was to be carried out without hesitation or reservation, in full intellectual honesty, giving a complete account of the possible insufficiency of the material or unreliability of the result. (...) “

The court mentions sardonically the judge-appointed expert’s “intellectual honesty”, and that is a very striking comment when found in a Supreme Court ruling: since the Cassazione is not a fact-finding panel, they don’t write about factual conclusions unless they appear prima facie as manifest and undisputable.

So the Supreme Court considers there are problems of intellectual honesty in the work of Vecchiotti and Conti, something manifest and obvious; the Court acknowledges they are obvious, something that anyone can see, which does not require a fact-finding by a judiciary organ to be pointed out.

Now the Carabinieri RIS report may bring further discredit upon Vecchiotti and Conti, if they have any credibility left. There are at least two reasons for this:

1) Because the finding of a reliable DNA profile belies the assessment that was given by Vecchiotti and Conti that extraction of a profile would be impossible, and demonstrates that in fact it was possible to extract a reliable profile; incidentally the fact that a Carabinieri RIS test was ordered itself implicitly denies Hellmann-Zanetti’s assessment that any result from 36-I would anyway be useless because contamination could have occurred outside the laboratory; but also it credits Novelli while it discredits Veccchiotti and Conti on a scientific level,  because it explicitly denies the idea that small (Low Template) DNA amounts are unreliable.

2) Because the Carabinieri RIS test employs the method proposed by Novelli, that is to couple Stefanoni’s “˜biologic’ analysis method with the statistical probability assessment method, in order to come to a certain attribution. Moreover, the Carabinieri RIS also point out that they can do this by assessing only 11 loci from a complex trace which also has foreign alleles (whereas trace 36-B analysed by Stefanoni was a “˜clean’, non-mixed profile matching a 17-loci sequence).

The Carabinieri RIS ran the test in “˜duplicate’ while Stefanoni made a single profile extraction. The Carabinieri point out that they can do this ““ divide even a smaller and more complex trace, and test it for comparison even on a smaller number of loci - because they now have “a system with extremely higher analytical performance which is able to provide result quantitatively and qualitatively better compared to previous systems”.

Why DNA Test Results 6 November May Leave No Further Argument Over Knox And Sollecito Guilt

Posted by Peter Quennell

[Above: an image of similar testing in the same Carabinieri laboratory in north Rome]


The official results of the tests by the Carabinieri laboratory will be made public by Judge Nencini in court on 6 November.

The report and attachments are reported to be more than 100 pages long. Andrea Vogt has already warned that no assumptions should be made yet that we know the full story. But already for the defenses, matters do not look pretty.

1) It sounds like the result of the DNA near the top of the blade (see images below) shows conclusively that it is another sample of Knox’s DNA. Given where the sample came from it could be blood DNA and add further proof to the notion that Knox was injured while struggling with Meredith.

2) The low-copy-number amplification technique used was almost identical to that used by Dr Stefanoni to prove that it was Meredith’s DNA on the blade of the knife - actually that was a larger sample. Judge Massei’s court accepted this, Judge Hellmann’s consultants tried very hard to undermine it, and the Supreme Court ruled that they did not even come close.

Earlier this year, our main poster Fly By Night in a post worth re-reading explained just how conclusively the results of that first testing pointed to both Meredith and Knox.

As is typical of all DNA analyses, Stefanoni proceeded to amplify the results to a point where an electropherogram would reveal meaningful “peaks” and found that a resultant 13 pairs of peaks corresponded precisely to peaks derived from a known sample of Meredith Kercher’s DNA!

In this case it is pointless to attempt to argue that Stefanoni somehow exceeded the amplification limits of her equipment. As outlined in the DNA discussion above, the typical problems associated with an amplification of low levels of DNA are related to peak imbalances, enhanced stutter, allele drop-outs, or allele drop-ins.

In this case there was nothing but a perfect match for Meredith that even Carla Vecchiotti and Stefano Conti could not deny in court.

Stefanoni had clearly identified an identical match for Meredith’s DNA on the blade of Sollecito’s kitchen knife, leaving Vecchiotti and Conti no other option than to argue for “contamination” in court.

However, it was convincingly demonstrated by Stefanoni and all evidence handlers that from knife collection through laboratory analysis no reasonable opportunity for contamination with Meredith’s DNA existed.

Dr Stefanoni’s testing of all the DNA from the crime scene was done in front of some defense observers. Those who were there saw her do nothing wrong. Dr. Patrizia Stefanoni, Dr. Renato Biondo, Professor Giuesppe Novelli, Professor Francesca Torricelli, Luciano Garofano, Elizabeth Johnson and Greg Hampikian have all confirmed that Meredith’s DNA was on the blade of the knife.

It looks as if the prosecution has now achieved a clean sweep of all of the of DNA testing. Meredith’s DNA on the lower blade of the knife seems even more conclusively a firm given, and so does Knox’s on the upper blade and the handle.

We are where we were back in 2008 before trial, where other defense lawyers might have suggested to their clients to select a trial of the short form type - the same choice that will see a somewhat penitent Guede out on work release in two years, no more.

But instead, their clients could now be facing life sentences for that bad choice.

The Meredith Case Wiki: A Highly Objective Summation Of The Case From Original Docs And Transcripts

Posted by James Raper

Some of our readers may not have noticed the new link to The Meredith Case Wiki to be found in the left hand column of this front page. I had not noticed it myself until recently.

This is an important link to a new website that is now a vital additional resource for those interested in understanding this case.

The website - The Murder of Meredith Kercher - is run by Edward McCall, with the assistance of other contributors, and TJMK is pleased to acknowledge and promote its distinctive and concise approach to presenting the facts of the case.

The site is modelled on the format of a page from the Wikipedia free encyclopedia.  As with a Wiki page it is easily navigable. The data presented under the various headings is the consequence of much research but it still remains a work in progress. Wherever possible the material used is referenced in footnotes.

It starts on the Main page with a Mission Statement and an Introduction to the case. It then considers the evidence and has a good section entitled Myths Debunked.

The reader can easily access significant court documents: the Massei Report, the Hellmann Report, the Galati Appeal and the Supreme Court of Cassation Motivations Report. There is an accessibly summary of the Matteini and Micheli Reports.

In particular, for the researcher, there is a most welcome section entitled Court Transcripts. Here can be found transcripts of witness testimony from the Massei and Hellmann trials, experts reports, and the various writings and testimony of Amanda Knox, Raffaele Sollecito and Rudy Guede. At least that is to be the hope ultimately as there exist a good number of gaps at present.

Already some of the witness statements have been translated from Italian to English but there are a number of transcripts still to be translated. If there are any translators who would wish to help, please contact us and we shall be pleased to put your name forward.

McCall wishes to acknowledge the massive contribution made by True Justice for Meredith Kercher. TJMK has perforce grown organically and exponentially over the years and has accumulated a breadth and wealth of data, in-depth analysis and informed comment on the case which is unsurpassed on the internet, or indeed anywhere.

It will continue to do so and report developments until the conclusion of all aspects of the case.

Carabineri Labs Might Prove Fourth And Conclusive Scenario For The Mixed DNA Samples In The House

Posted by Peter Quennell

Lab work is believed to have continued today in the absence of the defense observers, and will continue on and off through to October 30th.

The defense observers may not have a further role at the laboratory. Most or all of the analysis leading to firm attributions of the DNA will be done by the Carabinieri team electronically.

It is that final attribution that the defenses are widely rumored to be so terrified of. That Knox’s DNA is there seems a given. The cliffhanger is whether Meredith’s DNA is there also.

Another possible mixed trace. If so it would be the sixth one.

Judge Massei did not arrive at a full scenario for how the five mixed blood traces at the crime scene could have been created. He described what was found by crime scene investigators and moved on.

After the 2009 Massei trial some further analysis was conducted. 

With great help from Luciano Garofano’s DNA chapter in Darkness Descending and Barbie Nadeau’s and Andrea Vogt’s excellent reporting, we posted a comprehensive update mid-2011.

The locations of the five mixed traces at the crime scene are as follows.

1. Bathroom near Meredith’s room:

• On the drain of the bidet
• On the Q-tip box located at the ledge of the sink
• On the edge of the sink

Elsewhere in the apartment:

• In a luminol-enhanced bare footprint in the hallway outside Kercher’s room
• In a luminol-enhanced spot found in Filomena Romanelli’s room

Three sources for Knox’s blood have long been suggested: some bleeding from her ear, some bleeding from a possible nosebleed, some bleeding from the open scrape on her neck. .

All three of them could theoretically have been inflicted by Meredith as she struggled with the trio to save her life. None seem to explain why there were repeated MIXED traces.

That has remained a huge puzzle. But now we are looking at a fourth scenario: that Knox cut her hand with the top end of the blade as she stabbed at Meredith’s neck.

That could explain once and for all where Amanda Knox’s blood came from AND why it was mixed with Meredith’s blood. It happened right there.

DNA Tests: Umbria24 Reporter Francesca Marruco Provides A Balanced Overview Of Possible Prospects

Posted by ziaK

It may be that today or any day this week a definitive analysis of the seeming mixed DNA sample appears from an authoritative source.

Perugia-based Francesca Marruco did a lot of careful balanced reporting from Perugia early in the case. She has excellent official sources. She suggests in this report that the world might have to wait for the last day in October (deadline for the labs to report their analysis) or 6 November (next scheduled court session) for the official bottom line.

This is my translation. I am Italy-based also.

Kercher trial: unconfirmed reports on Amanda’s DNA: The experts will lodge their report [their truth] on the 30th [October]

By Francesca Marruco

The “I” trace identified on the blade of the knife could have come from the American woman, however the data could lend itself to contrary interpretations. The sentence could arrive before 30 November.

In order to obtain the definitive results of the analyses that the carabinieri of the RIS in Rome are carrying out on the “I” trace identified on the blade of the knife which is considered to be the weapon with which Meredith Kercher was murdered, we will have to wait until 30 October - the day on which the experts appointed by the Assise Appeal Court of Florence will lodge their conclusions. Already on Friday, the day on which the analyses were begun in the experts’ laboratories, uncomfirmed reports began to be leaked concerning the origins of that tiny quantity of DNA.

These leaks would like to ascribe it [the DNA] to Amanda Knox, the American student who was initially convicted and subsequently acquitted for the homicide of her flatmate, Meredith. But there is, as yet, neither certainty nor officiality, and - as this long case has taught us - even in the presence of officiality, opposing interpretations may be formed. If, in fact, as is being rumoured, those tiny biological particles did actually belong to Amanda Knox, this information could be interpreted in many ways.

Opposing interpretations - The defence would hasten to say that since Amanda had spent time in Raffaele Sollecito’s house - where the knife was discovered - there would be nothing strange if her DNA were to be on the blade. Just as - and this, at least, has been clearly seen - Amanda’s DNA was found on the handle of the weapon. Its presence could be explained by any banal procedure in the kitchen.

And indeed, Knox’s own defence has always maintained that the highly-contested trace “H” - the other trace identified on the blade, and which according to some is Meredith’s DNA - is nothing more than potato starch.  Thus, Amanda would seemingly have left her trace on the knife while peeling potatoes.

Traces - It is very clear, however, that the Prosecution could claim that precisely that presence of Amanda’s DNA on the blade of the knife could be proof that Knox touched it. To peel potatoes, or to kill her flatmate Meredith, as the Prosecution holds? If it is confirmed, one can bet that the data [found by the RIS] will give rise to an “earthquake” and it will fall to the judges of the Florentine court to clear up the resuting debris.

On the other hand, they might decide not to consider it [the data] any more than the other elements [of evidence], since it effectively lends itself to a multiplicity of [possible] interpretations which cannot be confirmed at this point in time. Certainly, if that trace were that of the victim, Meredith Kercher, the proceedings might take a different direction, since there would then be two [traces] at that point, and not just one trace of the victim’s DNA which would have ended up on the blade of a knife which she never touched during her lifetime.

The certainties, or rather, the conclusions, of the experts will be lodged on 30 October. It is the 6th of November, however, which has been appointed for the hearing during which these results will be discussed before the Court and the parties.

Towards the verdict - Raffaele Sollecito may also be present in court on that date, as he announced via his lawyers, Giulia Bongiorno and Luca Maori. Sollecito intends to make various spontaneous declarations in order to affirm once again his non-involvement in the barbarious murder of Meredith Kercher, for which only Rudy Hermann Guede is currently in jail, with a sentence of 16 years in prison which has been confirmed[by the Supreme Court]. 

After the hearing in which the results of the tests entrusted to the Rome RIS will be discussed, it is very probable that the trial will travel rapidly towards sentencing - the fifth sentence pronounced by an Italian court with regard to Raffaele Sollecito and Amanda Knox. The Court President [leading judge], Alessandro Nencini, said during the first hearing that “this is a trial for matters of undeniable seriousness. Over and above the media circus, is Court’s desire to give all parties the most space possible for discussion, because there was a very significant sentence/conviction originally.”

By November -  For this reason, “in order to obtain every possible factor for the matter we are trying here, the Court orders that the trace should be examined by the staff of the RIS in Rome”. The Florence Court’s sentence could thus arrive by the end of November, or at the latest by the end of the year. It is very unlikely that Amanda Knox will decide to be present at any of the hearings, and probably she will await the verdict in Seattle.

Perhaps the final word shall never be pronounced on the most Press-covered trial in Italian legal history. After this latest sentence, in fact, nothing prevents anyone from making further appeals to the Supreme Court.

The Carabinieri Laboratories In North-Central Rome Where Now Two Different Samples Need Attribution

Posted by Peter Quennell

Third update

Italy-based freelance reporter Andrea Vogt has tweeted the following: Leaks suggest DNA on knife shows knox genetic profile, but there is another profile being studied. Too early to interpret

Second update

Excellent comment on PMF by the poster Hugo which explains how the balance hasn’t changed.

The song remains the same. The republic contends that Amanda Knox used that knife to murder Meredith Kercher. The knife has yielded the DNA of just two people: Knox, in a position which indicates that she was gripping it, and Meredith, in a position which indicates that she was stabbed with it.

The defence can easily claim that Knox’s trace results from normal culinary use (although Stefanoni said the handprint indicated an atypical stabbing grip, with the knuckles on the same side as the blunt edge of the blade, and not a normal culinary cutting grip, with the knuckles on the same side as the sharp edge).

The problem is Meredith’s DNA at the sharp end. ‘Independent court-appointed expert’ Carla Vecchiotti admitted on the stand that this could not have arisen from laboratory contamination.

Professor Christopher Halkides’ suggestion that the contamination occurred during collection, because Stefano Gubbiotti acquired Meredith’s ‘aerosol DNA’ on his clothing, when he was supposedly in the house the same day, almost a week after the murder, and thus transferred the DNA from his clothing to his fingers to his evidence-handling gloves to the knife when he took it from Finzi’s envelope and re-packaged it in a stationery box at the Questura, is self-evidently absurd, fanciful, fictional and completely outwith the realms of actual forensic science.

And it’s not in evidence anyway, so it’s not an option open to the court.

Plus the objection to low copy number DNA is an American superstition not recognised in Europe. Unusually, it’s a scientific area where the US lags well behind. So you get hillbillies like Bruce Budowle grumbling, ‘Cain’t rightly say what that there newfangled LCN is, but ah reckon ah’m agin it.’ You’ll recall that a British appeal court has found that Bruce Budowle hasn’t the faintest idea what he’s talking about and also that, like Halkides, he tends to cite sources that don’t actually say what he says they say.

Knox is there on the hilt of the knife. And M is there near the point of the blade, and she’s trying to tell us something.

First update

The gap between the blade and handle of the knife was apparently widened to obtain the sample for the test. Sollecito lawyer Maori has claimed it is Amanda Knox’s. It is apparently adjacent to her previous trace.

If that is the case, the strength of the DNA evidence (which is very strong) remains unchanged. Dr Stefanoni identified Exhibit 36 on the blade as a strong trace of Merediith’s DNA. This was supported by various experts.

No contamination of that trace has ever been proved - or even a convincing contamination scenario put forward - and the video on top of the post below shows how the DNA charts for the sample and for Meredith totally match.

First post

Human DNA is widely reported in Italy to have been established from the sample never before tested on the large knife.

We may have to wait on an announcement from Judge Nencini in Florence as to whose DNA it is. That may not happen today.

These labs in the Carabinieri barracks are not far from the center of Rome. They are very well know to Italians because (images at bottom) “RIS” the Italian version of the show “CSI” is set there.

Testing Of The DNA Sample Starts Today Though Possibly No Results Announced Before 6 November

Posted by Peter Quennell

1. ViaDellaPergola’s video

That video from 2010 illustrates how the existing positive tests described in the Massei Report were crystal-clear; subsequently Hellmann, Zanetti, Conti and Vecchiotti (all now being investigated) so muddied the water.

2. From our short-form Massei Report

This is from Part Three of the four-part abbreviation of the Massei Report done by Skeptical Bystander and a PMF team in mid-2011.

Exhibit 36: The double DNA Knife

Exhibit 36 is a 31 cm long knife with a 17 cm blade and a dark handle.  It was seized from the kitchen cutlery drawer at Raffaele Sollecito’s home, located at 110 Corso Garibaldi in Perugia, on 6 November, 2007 when Chief Inspector Armando Finzi was ordered to perform a search of Sollecito’s residence.  This exhibit is important because “Sample 36b” taken from a scratch on the knife blade yielded Meredith Kercher’s biological profile.

After putting on gloves and shoe coverings, Finzi and his team entered the home.  They noted a strong smell of bleach.  Opening the cutlery drawer, they saw a big, “extremely clean” knife.  In Sollecito’s bedroom they found a second knife.  The knives were bagged and sealed.[106]

Exhibit 36 was carried back to the police station, where it was placed in a box for shipping to the Polizia Scientifica in Rome.  Dr. Stefanoni was the recipient of the box containing the knife in Rome.  All parties testified that standard procedures were followed to avoid the risk of contamination.

On 4 November, 2007, Meredith’s roommates Filomena Romanelli, Laura Mezzetti, and Amanda Knox had been taken by the police to look at the knives in their kitchen at the apartment in Via della Pergola.  Personnel from the Questura reported Amanda’s “severe and intense emotional crisis, unlike [the reaction of] the other two girls”.[292]  This behavior was contrasted to Amanda’s behavior at Police headquarters two days earlier:

“This circumstance appears significant both in its own right and also when one considers that Amanda had never previously shown signs of any particular distress and emotional involvement (in the Police headquarters, on the afternoon of November 2, Meredith’s English girlfriends, Robyn Carmel and Amy Frost in particular, according to their declarations, had been surprised by the behaviour of Amanda, who did not show emotions).”[292]

Investigators’ attention was alerted to the Exhibit 36 knife because of Amanda’s inconsistent behavior.  Later, police overheard a jail conversation between Knox and her parents on 17 November, when Knox said, “I am very, I am very worried about this thing with the knife ... because there is a knife of Raffaele’s ...”.[292]

Exhibit 36 thus became a central piece of trial evidence.  The debate would subsequently be focused on two issues: The compatibility of the knife with the large stab wound in Meredith’s neck; and the reliability of the DNA analysis.

Considering the first of these points, although the knife blade is 17 cm long, the depth of the larger wound is just 8 cm .  This “discrepancy” was the basis of defense efforts to discredit the knife as a murder weapon. The compatibility of the Exhibit 36 knife and the larger of Kercher’s wounds is addressed by Professor Bacci (see p. 121 of the Massei report).    Professor Norelli maintains that “it is not said that a blade is always embedded (plunged into) the target right up to the handle; the blade may also go (in) only to a certain portion of its length, and not right up to its end”.[126] 

It is noted that the movements of the victim may have played a part in determining the depth of the cuts.  “If I insert a centimeter of the blade into the victim and the victim suddenly moves towards me, how much of the blade will be driven inside the body surface area is absolutely unpredictable and depends on the action of both”.[129]  Alternatively, the blade of the knife might have met an obstacle. The cutting action is described on p. 146 and again starting on p. 152.

Defense witness Dr. Patumi disputed the compatibility of the wounds with said knife, arguing that a blade of 17 cm length could not have caused a cut 8 cm deep; see p. 156-157.  However, the Court rejected “the thesis of the incompatibility of the most serious wound and the knife Exhibit 36”, holding this thesis to be “unacceptable” .[172]

Regarding the second point ““ that of the DNA analysis ““ Dr. Stefanoni was the responsible expert at the crime lab in Rome. Although no biological traces were visible to the naked eye on the face of knife blade, Dr. Stefanoni perceived scratches - “anomalies in the metal’ - on the blade when rotating the blade under strong lighting.  The streaks were:

“... visible under good lighting by changing the angle at which the light hit the blade, since obviously the blade reflects light and thus creates shadows, making imperfections visible.”[196]

Sample 36b was taken from one of these points on the blade.  The genetic profile of Meredith Kercher was identified from this sample. Stefanoni presented charts to the court, showing the DNA profile: she noted “that the peaks were a bit low, but that without doubt were still within the range that is considered useful for testing a specimen (page 108). Although of a much lower quantity of DNA, the profiles were nonetheless very present and, by making a comparison with Meredith’s profile, Dr. Torricelli reported that “šwe find all the alleles, and we find them to be equal to those obtained from the swab taken, from the sample taken from the wound. Therefore in this case too, without doubt”› -she continued- “šalthough we are confronted with a sample that contains very little DNA, it nonetheless contains the DNA of only one person and is therefore comparable to Meredith’s; with regard to this knife, I would say I have no doubt in interpreting it: specimen A with Amanda’s profile and specimen B with the profile, compatible with that of Meredith.”[231-32] However, the amount of DNA was small and it was all used up in order to run a single test.

The defense objected that it was impossible to evaluate whether the actual nature of Sample 36b specimen: 

“.. when we have a small amount of DNA we talk about low copy number DNA, and that when this type of DNA is present, we are indeed able to carry out our amplification and obtain a profile, but we must remember that we may have lost one of the alleles, we may have an allelic imbalance ... it becomes very difficult to distinguish from a real allele, so that when working on ...  small quantities of genetic material, it is necessary to be very cautious in interpreting the results.”[237]

To this point, Dr. Stefanoni argued that it is preferable “to know to whom a biological specimen is attributable, rather than ascertaining the nature of that specimen, without attributing it to anyone.”[288]

Furthermore, it was argued by the defense that the quantity of DNA was too low to be able to perform the tests and consider the results reliable.  Given a low amount of DNA, the risk of contamination is high - particularly given the very numerous number of samples being analyzed.
 
The court rejected the possibility of contamination because no anomalies were ever identified in the Polizia Scientifica’s analytical process. The Prosecutor pointed out that all tests had been carried out in the presence of a lawyer/consultant for the defense - who had raised no objections during the testing.  The possibility of contamination during the collection of evidence was rejected based on a detailed consideration of the collection process.

Thus, the DNA from Meredith which was found on that knife cannot be traced back to any contamination occurring in the house in which it was found, or to the method of acquisition of the knife on the part of Finzi, or even to the collection and dispatch methods used by Gubbiotti. In addition, as has been said, that such contamination could have been carried out by the laboratory is also ruled out.[266]

In addition, Dr. Stefanoni testified that she did have the biological profile of the defendants, but did not employ them while interpreting the electrophoresis diagrams. Nevertheless, the Massei report judges that:

“... the main criticisms advanced by the defense concerned precisely this very small DNA quantity, and it raised the question of the reliability of the result obtained.”[288]

To this central point, Dr. Stefanoni:

“Regarding the too low quantity of DNA, Dr. Stefanoni declared, as has been seen, that even in the case of a particularly scanty amount of material, the analysis and evaluation should be performed, and she added that, if the data that emerges is absolutely readable and interpretable and the correct laboratory practice was followed, the result is reliable and there is no reason to repeat the test.

“It does not follow ... that the data is unusable and unreliable as a consequence of a lack of repetition due to a lack of further quantities of DNA. It is necessary, instead, to take account of the data that emerges from such a specimen and to check for the ““ possible ““ presence of other elements, both circumstantial and inherent to the data itself that, despite the lack of repetition of the analysis, could allow an evaluation of the reliability of the analysis and of its outcome.”[289]

The court concluded that the biological profile that resulted from the 36B DNA analysis ...

“... gave a biological profile attributable to the person who was mortally wounded with that very knife: a result, therefore, that was entirely reasonable and consistent with the event; [it was] certainly not explainable as a mere coincidence, and it must be ruled out ““according to what has already been observed in this regard - that it could have originated from contamination or from the use of a suspect-centric method.”,[290] and that

“”¦. it should therefore be affirmed that the analysis of trace 36B, which detected the presence DNA attributable to Meredith, appears to be completely reliable.”[293]

Scroll down to UPDATE OCT. 9, 2013 An excellent weighting of the possibilities.

The DNA could be Meredith’s, which would dramatically hurt thr defenses. It could be Rudy Guede’s, which would dramatically hurt thr defenses. Or it could be neither (or untestable) which would nt neccessarily affect the outcome. .
