"I've lost a friend in the worst, most brutal, most inexplicable way possible," she said in an emotional, 10-minute address. Watch below.

Her roommate Meredith Kercher, 21 was found stabbed to death in her bedroom in 2007. In 2009, Knox and Raffaele Sollecito were convicted of sexually assaulting and murdering Kercher. Knox was sentenced to 26 years (she has been jailed for four years), and Sollecito to 25. They have both denied involvement.

A jury may overturn the conviction Monday; Judge Claudio Pratillo Hellmann said it would not return from deliberations before 11 a.m. PT. The verdict will be broadcast live. CBS News reports that there are hundreds of reporters and cameras outside the courtroom.

"I'm paying with my life for things that I didn't do," Knox added in Italian while fighting back tears and occasionally pausing to catch her breath, CBS News reports.

"She had her bedroom next to mine, she was killed in our own apartment. If I had been there that night, I would be dead," Knox said. "But I was not there."

"I did not kill. I did not rape. I did not steal. I wasn't there. I wasn't there at the crime," Knox went on. "I insist I'm innocent and that must be defended. I just want to go home, go back to my life."

48 Hours Mystery's Peter Van Sant says that several members of the jury openly wept, as did journalists who have been covering the case.

Sollecito -- who met Knox just as he was finishing up his graduate degree -- also addressed the courtroom Monday: "I never hurt anyone, never in my life."

The murder weapon recently underwent more DNA testing that ruled Knox's DNA was "proved to be insufficient to convict."
