(ROME) -- A convicted child murderer testified in an Italian courtroom Saturday that American college student Amanda Knox was not involved in the 2007 murder of her roommate.
Mario Alessi, who is serving 30 years behind bars for the kidnapping and murder an Italian toddler, said he was told by drifter Rudy Guede that Knox and her ex-boyfriend Raffaele Sollecito were not involved in the murder of Knox's roommate, 21-year-old Meredith Kercher, who was found dead on November 2, 2007 at the home she shared with Knox in the city of Perugia.
Guede has denied the allegations by Alessi, who testified in Knox's appeals hearing Saturday.
In December, 2010 Knox was sentenced to 26 years behind bars for the killing of roommate Meredith Kercher. Sollecito was also found guilty of murdering Kercher, and is serving a 25-year prison sentence.
Both Knox and Sollecito have appealed their convictions.
Guede is serving a 16-year sentence for his role in the killing.
