Headsup: Disney's Hulu - mafia tool?! First warning already sent to the Knox series production team about the hoaxes and mafia connections. The Daily Beast's badly duped Grace Harrington calls it "the true story of Knox’s wrongful conviction of the murder of her roommate". Harrington should google "rocco sollecito" for why Italians hesitate to talk freely.

Trial: Patrizia Stefanoni Seen Here With One Of Her Teams

Posted by Peter Quennell

These teams seem to professionals we know watching the case to be smart, efficient, and well-organized.

And large. The numbers involved in the various searches and analyses have been quite considerable.

They all arrived in Perugia from Rome of course. From the equivalent of Scotland Yard or the FBI.


Trial: The Morning Report By Sky New’s Nick Pisa

Click above for the full story.

DNA from Meredith Kercher murder suspect Amanda Knox was found on the handle of a kitchen knife and Miss Kercher’s DNA was on the tip, a court has heard…

On Friday, forensic scientist Patrizia Stefanoni told the court how her team had recorded 460 biological traces at the crime scene.

Dr Stefanoni also said DNA traces were found on a black-handled kitchen knife recovered from Sollecito’s flat - which the court has been told is compatible with the murder weapon.

She showed photographs of the knife and pointed out the areas of the handle where Knox’s DNA was found, and the tip of the blade where Miss Kercher’s was found.

Dr Stefanoni told the court that blood tests on the knife had proved negative, and in earlier hearings the judge and jury were told that the knife had been cleaned.

DNA from Knox and Miss Kercher was also found in blood stains found in the bidet of the bathroom, the sink and on a box of cotton wool buds, the court heard.

Dr Stefanoni said the bloodstains were “slightly pink as if the result of being washed”....

The court heard how DNA from Sollecito was found on a metal clasp that had been cut away from Miss Kercher’s bra and which was found at the scene.

A blood stain found in the bedroom of flatmate Laura Romanelli was also found to have DNA from Knox and Miss Kercher.

That last line sure surprised us! But we think Nick Pisa may have intended to write Filomena Romanelli and not Laura Romanelli at that point.

Mixed-blood evidence found in either bedroom would appears to be very important new news, and even tougher for the defense teams than the mixed bathroom traces.

We remain grateful for Nick Pisa’s fast reports. The London Times, in contrast, has not posted any report on the trial for quite some time now.


Today’s Witness Patrizia Stefanoni Shakes Hands With Prosecutor Giuliano Mignini

Italian media have reported that the first part of Ms Stefanoni’s deposition was a sort of seminar on how to catalogue and collect forensic evidence and exhibits.

From La Nazione: “We use kits which are internationally recognized and marketed. This means that a researcher in Sydney, Australia, looking at the same tube would see the same outcome in terms of results of the DNA. For our investigation of the death of Meredith, two different special kits were used to analyze the DNA and other genetic traces.”

She then testified that 460 biological traces were collected and analyzed. And that 360-degree images of each room were taken in advance of each of the team’s search for more evidence. She excluded contamination by her operatives.

“In collecting traces of bloodstains, it is crucial for the operator not to come into contact with them, not to alter the scene, and to avoid being infected by bacteria or viruses. Therefore we use special gloves, boots, masks and coveralls.”

Ms Stefanoni’ found no biological evidence under Meredith’s short fingernails, which she found not unexpected as Meredith was apparently fighting off a knife attack and then down on her hands and knees.

It is perhaps worth recalling that Ms Stefanoni presented essentially the same evidence at the trial of Rudy Guede. Judge Micheli seems to have found it extremely credible, as it forms a large part of his report.

Judge Micheli then awarded Guede a term of 30 years in prison, and Prosecutor Mignini had only asked for 25.


The Trial Resumes: The Court Agenda For Friday And Saturday

Posted by Peter Quennell

Italian media have reported the following agenda for Friday and Saturday.

Probably all day Friday: Patrizia Stefanoni. leader of the forensic team, who will testify on the crime scene and what was found where and how it was collected.

Probably all day Saturday: Francesco Camana, who will testify on the bloody footprints revealed with luminol, and then Giuseppe Codisposti and Piero Sbardella, who will testify on the second collection of evidence and the prints found on the pillow.

We are anticipating (see our right column for dates) that there will be no court sessions next Friday and Saturday because a public holiday in Italy renders this traditionally a long weekend.

Meredith’s mother and perhaps other members of the Kercher family are expected to testify at the next session on 5 or 6 June.

And in a Seattle PI interview, Curt Knox has confirmed that Amanda Knox wants to testify at the session after that on 12 or 13 June.

Soon thereafter, all Italian courts will cease sessions for a period of some weeks during the vacation period.

The defense phase of the trial will resume in September and the trial may be over in October and the verdicts and sentences, if any, announced then.

If the verdicts are “guilty” appeals are automatic under the Italian system..

Trial: The Beast On The Footprints -  And Meredith’s House

Posted by Peter Quennell


Click above for Barbie Nadeau’s report on last Friday and Saturday at court.

Amanda Knox’s father is interviewed. And we are quoted on Meredith’s house as follows.

The Daily Beast also discovered that administrators of one of the blogs that follows the Kercher trial, True Justice for Meredith Kercher, is considering buying the House of Horrors to make sure it isn’t forgotten. “Increasingly, Meredith’s followers seem to hope that the groundswell for Meredith evolves into something tangible.

Making an offer for the Via della Pergola house, perhaps establishing a memorial garden there, is one possible objective,” Peter Quennell, who runs the True Justice site, tells me. “Meredith is clearly coming to stand for something transcendent. She already seems an iconic presence for many followers of the case.”

In our incoming emails, compassion for Meredith is mounting higher and higher, and this flows in part from an obvious sadness that the house might revert to a student rental or grim tourist attraction.

The Kercher family have not testified about Meredith at the trial yet - that might happen in three weeks. We feel it appropriate to simply float this possibility and no more for now.

Trial: Andrea Vogt Provides More Detail On The Bloody Footprints

Posted by Peter Quennell



Click above for the report on the Seattle PI website.

1) From the prosecution testimony

Over the opposition of both defense teams, Lorenzo Rinaldi demonstrated to jurors using a precise Power Point presentation why the visible bloody footprint left on the cotton bath mat in the bathroom is attributable to Sollecito, who is on trial along with Knox for murder of her British roommate, Meredith Kercher, in November 2007….

“All the elements are compatible with Mr. Sollecito’s foot,” Rinaldi said, pointing with a red laser to a millimeter-by-millimeter analysis of Sollecito’s footprint projected onto a big-screen in the courtroom. He used similar methods to exclude that the footprint on the bath mat could possibly be Guede’s or Knox’s…

The next witness, another print expert, again confirmed Rinaldi’s testimony, that the print, which only shows the top half of the foot, matches the precise characteristics of Sollecito’s foot.

Two luminol-enhanced bare footprints were also found compatible with Knox’s right foot, Rinaldi said, one exiting her own room and another in the corridor outside Kercher’s door, facing toward the room.

All the bloody shoeprints in the room where Kercher was found were compatible with the size 11 Nike Outbreak 2 shoes believed to be Guede’s, Rinaldi said, except for one smaller, unattributed shoeprint found on the pillow that was under Kercher’s body.

Presiding Judge Giancarlo Massei asked Rinaldi what size that shoe print was, he responded “37 or 38.” He then asked what size Knox wears, and Rinaldi said according to other shoes sequestered from the crime scene, she wears a 37.

A second print expert later testified that he believed the shoeprint to be that of a woman’s size 37.5 Asics tennis shoe. No Asics tennis shoes were among the 22 pairs sequestered by police from the three’s apartments.

Rinaldi’s detailed PPT described methods of image analysis, metric and grid measurement of the ball, toe, heel and arch, as well the particular characteristics of the footprints, shoeprints as well as the actual shoes and feet of Knox, Sollecito and Guede. The three suspects gave their footprints and fingerprints at police headquarters.


2) And from the cross-examination

On cross examination, one of Knox’s defense team, Rome lawyer Carlo Dalla Vedova, questioned the certainty with which the prints could be considered compatible with Knox’s foot. He noted that a match with Sollecito and Guede’s footprints was excluded, but asked why the luminol print was not compared with the other two female roommates in the house.

Under cross, Rinaldi also confirmed that luminol, a substance used by forensic police to reveal non-visible traces of blood, also could react to other substances that contain iron, such as fruit juices, chlorophyll or rust, as well as bleach.

When asked what substance the print was made in, Rinaldi said he does only image analysis and such a determination would have to be made by a forensic biologist. That witness is scheduled to testify at the next hearing. Defense teams have all hired their own forensic experts to testify during their presentations.

Trial: Italian-Language Video Report On Today’s Session

Posted by Peter Quennell


Click above for the video. It starts immediately.

Much of the focus is on Sollecito and his lawyer discussing the luminol-enhanced footprints - we hope not for the first time.

The lawyer in shirt-sleeves who stands up near the end is Mr Maresca, the Kercher family’s representative at the trial.

We are presuming that he will have a role in presenting the family’s testimonies, which may happen in three or four weeks.

Trial: At The Most Dramatic Day So Far, Bloody Footprints Seem Strong Matches To Defendants

Posted by Peter Quennell





This was a very dramatic day in court.

The footprint expert Dr Lorenzo Rinaldi [above], unit head from the Scientific Police in Rome, and Pietro Boemia were like pitbulls. The defenses were in shrill disarray,

Sollecito intervened very nervously and incredibly lamely (which did him real harm). And the judges’ eyes were glued to the presentation screen.

Click above for Nick Pisa’s lunchtime report.

Bloodstained footprints found at the house where British student Meredith Kercher was stabbed to death fit her alleged killers, a court has heard.

Forensic scientists found one imprint on a bath mat and three more in the corridor leading from Meredith’s bedroom to that of suspect Amanda Knox.

The court heard how imprints were taken of Knox, 21, and her former boyfriend Raffaele Sollecito, 25….

Police scientist Dr Lorenzo Rinaldi told the Italian court his forensic evidence was discovered by using Luminol - a substance that turns blue in the presence of blood.

“From our investigations we were able to conclude that the footprint found on the bath mat was compatible with that of Sollecito as was one found in the corridor using Luminol,” Dr Rinaldi said.

“We also found that a naked footprint found in Knox’s bedroom and in the corridor outside, again using Luminol, was compatible with the one taken from her in prison.”

Dr Rinaldi explained to the court how microscopic point to point measurements such as ‘‘heel to toe’’ or ‘‘toe and arch width’’ were used to identify the imprints.

Subsequently Andrea Vogt of the Seattle PI reported at more length:

Bloody and luminol-enhanced footprints left in the villa where Meredith Kercher was murdered are those of Raffaele Sollecito, Amanda Knox and Rudy Guede, the director of print identity in the Rome forensic police division testified Saturday.

Over the opposition of both defense teams, Lorenzo Rinaldi demonstrated to jurors using a precise Power Point presentation why the visible bloody footprint left on the cotton bath mat in the bathroom is attributable to Sollecito, who is on trial along with Knox for murder of her British roommate, Meredith Kercher, in November 2007. Guede was convicted and sentenced to 30 years prison for his role in the crime in a separate fast-track trial last October.

“All the elements are compatible with Mr. Sollecito’s foot,” Rinaldi said, pointing with a red laser to a millimeter-by-millimeter analysis of Sollecito’s footprint projected onto a big-screen in the courtroom. He used similar methods to exclude that the footprint on the bath mat could possibly be Guede’s or Knox’s.

“Those bare footprints cannot be mine,” said Sollecito in a spontaneous statement after the lunch break. He and Knox maintain they were at his apartment the night Kercher was killed. “They are not mine.”

But the next witness, another print expert, again confirmed Rinaldi’s testimony, that the print, which only shows the top half of the foot, matches the precise characteristics of Sollecito’s foot.

Two luminol-enhanced bare footprints were also found compatible with Knox’s right foot, Rinaldi said, one exiting her own room and another in the corridor outside Kercher’s door, facing toward the room.

All the bloody shoeprints in the room where Kercher was found were compatible with the size 11 Nike Outbreak 2 shoes believed to be Guede’s, Rinaldi said, except for one smaller, unattributed shoeprint found on the pillow that was under Kercher’s body.

Presiding Judge Giancarlo Massei asked Rinaldi what size that shoe print was, he responded “37 or 38.” He then asked what size Knox wears, and Rinaldi said according to other shoes sequestered from the crime scene, she wears a 37. A second print expert later testified that he believed the shoeprint to be that of a woman’s size 37.5 Asics tennis shoe. No Asics tennis shoes were among the 22 pairs sequestered by police from the three’s apartments.

Rinaldi’s detailed PPT described methods of image analysis, metric and grid measurement of the ball, toe, heel and arch, as well the particular characteristics of the footprints, shoeprints as well as the actual shoes and feet of Knox, Sollecito and Guede.

Trial: The Trial Agenda For Today And Tomorrow Is Physical And Forensic Evidence

Posted by Peter Quennell


Click above for NIck Pisa’s report.

This is some of the more telling and contentious evidence. The same evidence was not successfully rebutted Last October at the trial of Rudy Guede.

1) The items in evidence

The court is now set to hear details of how DNA was found on a knife and bloodied bra strap.

Key to the proceedings will be evidence relating to a 30cm kitchen knife found at Sollecito’s flat days after the murder in November 2007. Forensic experts say DNA from Meredith was discovered on the blade.

They claim Knox’s DNA was found on the handle of the knife, which they say is compatible with the murder weapon that has never been found.

The experts will also detail how DNA from computer studies graduate Sollecito was found on a piece of bloodied bra. The material is believed to have been ripped from Meredith’s body.,,

Besides the knife, the prosecution also claims Knox’s DNA was found mixed in blood spots from Meredith found at the scene in the shower and sink.

2) The forensics team

The forensics specialists include chief of the Italian Scientific Police Unit in Rome, Patrizia Stefanoni. She was part of the Disaster Investigations Team sent to the scene of the 2004 tsunami to identify victims…

Ms Stefanoni has given evidence that her team used gloves and tweezers at all times. She insisted that, despite claims from the defence, there was “no possibility” of contamination.

Knox and Sollecito’s lawyers insist the DNA evidence is tainted as it was poorly handled. They have also pointed out how the bra fragment was only picked up six weeks after the killing during a second search of the scene.

Understanding Why The DNA Is On The Knife

Posted by Peter Quennell

[click for larger image]




Our DNA poster Nicki has been careful not to exaggerate the impact as evidence of the DNA on the knife found in Sollecito’s apartment.

She accepts that in the eyes of the court there could be question marks over the size of the sample and the fact that the tests could not be repeated.

However, as the knife appeared to have been thoroughly cleaned with bleach, some remain intrigued that any DNA at all was found.

Here is a short piece explaining why. This article by Juliet Lapidos was posted on the Slate site in November 2007. But we haven’t seen better, and it is still often referred to.

Slate 20 Nov 2007
How To Clean a Bloody Knife: Does DNA come off with soap and water?
By Juliet Lapidos NYTimes Staff Writer

Investigators in Perugia, Italy, have found new evidence linking a 20-year-old American exchange student, Amanda Knox, to the brutal stabbing death of her roommate, British student Meredith Kercher. According to the latest reports, Knox and her Italian boyfriend, Raphael Sollecito, cleaned the alleged murder weapon””an 8-inch black-handled kitchen knife””with bleach. Nevertheless, police discovered Kercher’s DNA on the tip and Knox’s DNA by the handle. Is it possible to clean DNA off a knife?

Yes, if you know what you’re doing. Knox and Sollecito were on the right track: Bleach contains sodium hypochlorite, an extremely corrosive chemical that can break the hydrogen bonds between DNA base pairs and thus degrade or “denature” a DNA sample. In fact, bleach is so effective that crime labs use a 10 percent solution (one part commercial bleach to nine parts water) to clean workspaces (PDF) so that old samples don’t contaminate fresh evidence. Likewise, when examining ancient skeletal remains (PDF), researchers first douse the remains in diluted bleach to eliminate modern DNA from the surface of bones or teeth.

So, why did Knox and Sollecito’s bleaching gambit fail? It’s difficult to swab a knife thoroughly. Dried blood can stick to the nooks and crannies in a wood handle, to the serrated edge of a blade, or become lodged in the slit between the blade and the hilt. With help from a Q-tip, it’s possible to eliminate most stains, but what’s not visible to the naked eye might still be visible to a microscope, and sophisticated crime labs need only about 10 cells to build a DNA profile.

Bleach is perhaps the most effective DNA-remover (though evidently no methodology is failsafe), but it’s not the only option. Deoxyribonuclease enzymes, available at biological supply houses, and certain harsh chemicals, like hydrochloric acid, also degrade DNA strands. It’s even possible to wipe a knife clean of DNA-laden hair follicles, saliva, and white blood cells with generic soap and warm water. The drawback to this last method is that the tell-tale cells don’t just disappear once off the knife. They linger on sponges, in drains, and even in sink traps, where wily investigators search for trace evidence.

There appears to be a great deal more DNA evidence than merely what is on the knife, of course, and early in the trial the known luminol-evidence universe also expanded.

The court was told that AK-sized and RS-sized footprints appeared under luminol on the floor of Filomena’s room.

Nicki’s two Powerpoints on the DNA can be seen here and here and Kermit’s Powerpoint (pre the new evidence) on the luminol can be seen here.
