The new forensic testing of the knife ordered by Judge Alessandro Nencini at the start of Amanda Knoxs appeals trial in Florence is going ahead at the Caribinieri RIS laboratories in Rome. But how crucial will the results be to appeal outcome? If the DNA being tested matches the profile of either the victim Meredith Kercher or the other man already in jail for the murder, Rudy Guede, it is a very ominous sign for the defense. If more of Merediths DNA is found on the blade, it further confirms the prosecutions assertion that the kitchen knife found in Sollecitos flat was indeed the murder weapon. If Rudy Guedes DNA is found on the blade, it confirms his story that he was stabbed in the palm by a knife-wielding attacker as he came out of the bathroom to see what all the fracas was about. Guede testified that the attacker said in Italian Black man found, black man guilty, before running out the door. He claims he found Meredith dying in her room and tried to save her, but, unable to stop the bleeding, eventually panicked and fled. Since Guede had never visited Sollecitos flat, the prosecution would like argue that his DNA on the blade meant that either Knox or Sollecito brought the weapon back there after the murder and confrontation with Guede.
If, on the other hand, the DNA results are inconclusive, the forensic evidence could be interpreted as weakened and there is more likelihood of acquittal, partial acquittal or conviction on lesser charges, such as omicidio colposo (manslaughter), options that remain open to the court.
