More than 100,000 messages with a mistress are now at the center of former "American Idol" contestant Caleb Flynn's murder trial. Prosecutors say Flynn repeatedly wrote about wanting his wife, Ashley, gone before she was shot twice in the back of the head while lying in bed. They allege he then staged the scene to look like an intruder had broken into their Ohio home. But his defense draws a clear distinction: "A man can fail as a husband without being a murderer." Flynn has pleaded not guilty, with his attorneys arguing the state lacks direct or forensic evidence that proves he pulled the trigger. ▻
