DNA Evidence on Alleged Murder Weapon Links Knox to Crime

In court testimony in Perugia Friday  forensic scientist Patrizia Stefinoni spoke regarding   forensic samples of evidence seized during the crime scene investigation in 2007.  One of those  reveals Amanda Knox's DNA on the handle of the  knife which matches the murder weapon description.  Ms.  Kercher's DNA is also found on the blade.  In early June,  the defense will refute each piece of evidence,  providing their own experts' testimony.
