Dr Stefanoni's testimony:
"Under a sometimes-heated cross interrogation by the defense lawyers for both Knox and Sollecito, Stefanoni defended her methods and denied the crime scene had been contaminated.
Sollecito would have had to rub the bra hook forcefully for DNA from his skin cells to be on it, she said. Dead skin cells floating around the room do not contain DNA and would not stick, she said."

Andrea Vogt:
"Over the course of six crime scene inspections, 228 pieces of evidence and 460 traces of genetic material were found. Stefanoni, who sat on the witness stand for 10 hours, presented slides and graphs describing the complicated science behind DNA analysis and defending her team's protocol.
Friday's key evidence focused on mixed genetic traces of Knox and Kercher found throughout the house. That's something, Knox's defense lawyers said, that was normal given that they lived together.
But mixed blood samples were found as well. Specifically, mixed blood of Knox and Kercher was found on the drain of the bidet, on a box of Q-tips sitting on the sink and the sink ledge.
A drop of Knox's blood was identified on the sink faucet. Kercher's blood was also found on the toilet lid and the bathroom light switch, on the part that would have been touched to turn on the lights. Elsewhere in the house, luminol-enhanced footprints were analyzed and found to be mixed genetic material of Knox and Kercher.
Tests on a spot of luminol-enhanced blood in roommate Filomena Romanelli's room (where the window had been broken with a large rock) revealed mixed DNA of Kercher and Knox."

On the knife:
"The Italian news agency ANSA quoted Stefanoni as testifying that traces of
Knox's genetic code were found in a small scratch on the knife's handle, and that the point in which the genetic material was found indicates that the knife "was used to pierce and not to cut."
After Stefanoni testified, Knox's lawyer told reporters outside the courtroom that the and that the defense was considering asking the court to order DNA testing by an outside expert."
