Italian police defend their Amanda Knox murder probe

September 5, 2011 12:00:00 AM PDT
An appeals trial is under way for Amanda Knox, the American convicted of killing her British roommate in Italy. Lawyers are questioning independent experts who cast doubt on the evidence used in the first trial.

An Italian police official who conducted the original investigation defended her standards in court on Monday.

Patrizia Stefanoni took the stand as Knox's appeals trial resumed after the summer recess.

A verdict in the appeals trial is expected by the end of the month.

Knox has been behind bars since 2007. She and her co-defendant and one-time boyfriend, Raffaele Sollecito, were convicted of sexually assaulting and killing Meredith Kercher in the apartment that Knox and the 21-year-old Briton shared while studying in Perugia.

Knox was sentenced to 26 years in prison; Sollecito to 25. Both deny wrongdoing and have appealed the Dec. 29 verdict.
