NOW TESTIFYING: Alleigha Botner, the woman prosecutors say had an affair with former “American Idol” contestant Caleb Flynn, has taken the stand in his Ohio murder trial. Prosecutors have pointed to the alleged affair and more than 100,000 lines of digital records tied to Flynn as they build their case that he killed his wife, Ashley Flynn, and staged the scene to look like a break-in. Botner was the main worship leader at the family’s church and performed alongside Flynn on the worship team, previous testimony revealed. Ashley’s sister testified Tuesday that learning about the alleged affair left her more shocked than she had ever been.
