On May 24, TMZ spoke with Santino Casio, the inmate charged with viciously attacking Tory Lanez at the California Correctional Institution in Tehachapi, Calif., earlier this month. Casio gave the celebrity news site his side of the story in his first interview since stabbing the Canadian rapper. Casio claims he and Tory were cool for a year after the entertainer arrived at the prison. However, recently, things became contentious. The day before the stabbing, Casio confronted Tory.

"I heard some rumors that he was trying to put money on my head," Casio says in the audio below. "He felt uncomfortable living next to me. He said I was a threat. So, I confronted him...He said I put money on his head. We had a little discussion or whatever."

Casio claims Tory said "all kinds of crazy sh*t."
