Expert: suffocation main cause of Briton's death

A British student killed in Italy in 2007 died from suffocation caused by her murderers, showing a clear intent to kill, as well as from the stab wounds inflicted to her neck, a forensic expert told a court Friday. As the expert took the stand, the family of victim Meredith Kercher arrived in this central Italian town to testify at the trial of an American student and her ex-boyfriend who are charged with murder and sexual violence. Kercher, a 21-year-old student from Leeds University in England, was found stabbed to death on Nov. 2, 2007 in the house she rented in Perugia, where she was an exchange student. Her roommate, Amanda Knox, also 21, and 25-year-old Raffaele Sollecito of Italy are standing trial. They deny wrongdoing.
