Significantly, they said no evidence supported the original police conclusion that Kercher's blood was found on a knife which they identified as the murder weapon and which had been handled by Knox.
The experts, Carla Vecchiotti and Stefano Conti, confirmed police conclusions that Knox's DNA was found on the handle of the knife but said material on the blade was from starch.
The experts also said there was no DNA evidence on a clip from Kercher's bra which police said was traceable to Sollecito, 27. The report was obtained by journalists at the court.
