Two inmates stepped forward to testify that AMANDA KNOX was not involved in the murder case she was convicted for.

In 2009, Knox, 23, was sentenced to 26 years in Italy after being convicted of sexually assaulting and murdering British student Meredith Kercher.

The two witnesses who tried to clear Knox's name,  may not be the most credible witnesses as they're both Italian convicts  — Mario Alessi, serving 30 years for murder and Luciano Aviello, a Mafioso.

The cons claim that Rudy Guede, who was sentenced to 16 years for his involvement in Kercher's murder, said that Knox had nothing to do with the murder. Instead it was committed by Guede and an unidentified accomplice.

Through his attorneys, Guede has denied the version of events that Alessi relayed.

Aviello took the stand and testified that it was his own brother who had committed the heinous crime against Kercher with an Albanian man.

During testimony Aviello gave conflicting versions, but said his brother confessed the murder to him.

Marco Castelluccio, a mafia member who is a protected witness, testified that Guede also told him that Knox had nothing to do with the murder.

Guede is expected to testify on June 27 as Knox appeals her conviction.
