Mario Alessi, a prisoner serving a life sentence for murdering a child, testified last week that Geude told Alessi that Knox and her former boyfriend Raffaele Sollecito, who was given 25 years for the crime, were innocent. Three other witnesses were called Saturday to corroborate the testimony. One witness claimed his brother had killed Kercher. The appeal trial seemed to be tilting in Knox’s favor.

But Guede, who was sentenced to 16 years for his role in the crime, took the stand for the prosecution Monday and denied Alessi’s claims. After he left the courtroom, Knox said, “He knows we weren’t there. ... I’m shocked and anguished by these statements.”

The case attracted a huge amount of media attention, with the trial being made into a Lifetime movie, “Murder on Trial in Italy,” starring Hayden Panettiere. Knox became a tabloid sensation, called both “Foxy Knoxy” and “the angel-faced killer with ice-cold eyes” by the media.
