A former Ohio music pastor who once appeared on “American Idol” has been convicted of murder in the killing of his wife while he was having an affair. A Miami County jury found Caleb Flynn guilty on Tuesday. Prosecutors alleged Flynn staged a home invasion in February after shooting his wife, Ashley. He claimed she was killed by a burglar. He appeared on “American Idol” in 2013, telling TV viewers about how his wife had encouraged him to chase his dreams on the singing competition. Flynn could get up to life in prison without the chance of parole when he’s sentenced on Monday.
