Testifying for the defense, he said the neck wound was made with a knife with a 3-inch long blade, while prosecutors maintain a 6 1/2-inch knife found at Sollecito's home could be the murder weapon. He also said there is no evidence that Kercher was assaulted by more than one person. On Friday, a police official testified that no break-in had been staged at the crime scene, casting doubt on another prosecution argument. Prosecutors say Knox and co-defendant Sollecito killed Kercher and then broke one of the apartment's windows from the inside to stage a burglary. A stone was found in one of the bedrooms, with shattered glass on the floor. Read These Next White House rolls with Trump's 'daddy' nickname. New Fox star, 23, misses first day after car troubles.
