DNA experts highlight problems with Knox case

PERUGIA, Italy — The investigators who collected the genetic evidence used to convict American student Amanda Knox of murder in Italy made a series of glaring errors, including using a dirty glove and not wearing caps, two independent forensic experts said Monday.
The experts had been appointed by an Italian appeals court to review the DNA evidence used in Knox's trial, including some found on a kitchen knife believed to be the murder weapon and some found on the clasp of the victim's bra.
But the independent experts told the appeals court that the collection of evidence fell below international standards and may have resulted in contamination. They used slides to refer to international protocols for the collection and sampling of evidence, including one from the U.S. Department of Justice and others from various U.S. states.
One of the two experts, Stefano Conti, cited several cases of forensic police entering the crime scene or coming into contacts with objects there not wearing protective equipment such as masks or hair caps. He said that while evidence should be wrapped in paper or kept in a paper bags, police often used plastic bags, heightening the risk of contamination.
"There are various circumstances do not adhere to protocols and procedures," the forensic expert told the court.
In footage and framegrabs shown to the court, two police officers collected the bra clasp, and the glove worn by one of the two appeared to be dirty on two fingers. Conti noted the bra clasp was collected 46 days after the Nov. 1, 2007 fatal stabbing of the 21-year-old Kercher.
"Over those 46 days several objects were moved, and in at the same time several people will have come in and out," he noted, again stressing the risk of contamination.
The other expert, Carla Vecchiotti, explained to the court that the genetic profile on the knife's blade that was attributed to Kercher is dubious and cannot be attributed with certainty. She said the original testing did not follow recommendations of the international scientific community for dealing with DNA testing.
Vecchiotti said the review concurred with the original testing in saying that the genetic profile on the knife's black plastic handle could be attributed to Knox. The knife was found at Sollecito's apartment.
The independent experts, both from La Sapienza University in Rome, will be questioned and cross-examined in the next hearing, scheduled for Saturday. That will be the last hearing before the summer break.
This morning in court in Perugia:

I guess Saturday is cross-examination, and then Aug/Sep will be reviewing and coming to the verdict. How I WISH this would just be over.![]()
apparently the blood and the hair on the window sill were exhibits R and S in RF's room. I looked at the hair. Looks to straight to be RG's for the life of me, I can't see the blood on spot S.

IIRC it did test positive with TMB. Yes it did come to think of it but subsequent tests said it was not
The experts finally brought up the fact the mattress was moved which of course would be filled with MK's DNA!!!
"Another element of non-compliance with international protocols, according to experts, the move would be no finding of many objects in the scene of the crime among the various inspections carried out by Science. The leading experts such as moving the hook - after finding 46 days - and the same mattress which was covered with Meredith Kercher. Mattress that was moved without any reason in another room of the house"

DNA evidence on the suggested murder weapon and a bra strap was not a positive match with any of the suspects, according to independent DNA experts. Furthermore, the experts suggest that investigators broke numerous protocols when gathering the evidence putting it in paper bags instead of plastic, and wiping down evidence as they gathered it, doing the opposite of the protocol the experts described. This is a major victory for Knox, who was jailed on that seemingly-faulty evidence.
