Student in Kercher trial 'had scratch on neck'

An American student accused in the stabbing death of her British roommate had a scratch on her neck hours after the killing, a witness testified today at the murder trial in Italy.

Laura Mezzetti, an Italian woman who shared an apartment with victim Meredith Kercher and defendant Amanda Knox, told the court she saw the scratch on November 2, 2007, at the police station where they were waiting to be questioned.
