Bill Cox, 55, has pleaded not guilty to killing his daughter's boyfriend in the middle of the street, but the tapes don't lie. In the 911 call Bill made minutes after getting into a fight and shooting Ryan Abner, 21, in the head, he told police: "I shot him and made sure he's dead. He's dead." He claims Ryan "beat on" his teenage daughter, but the distraught daughter (who has a child with Ryan) can he heard in the background of the chilling 911 tape denying she was a victim of abuse. Bill told her: "I'm gonna to go to prison over this, but it's worth it."
