A 60-year-old Tennessee man took an online feud too far when he allegedly killed a local couple because they'd deleted his adult daughter from their Facebook account.

According to the Johnson County Sheriff's Department, Marvin Potter was charged with two counts of first-degree murder after Billy Payne Jr., 36, and his girlfriend Billie Jean Hayworth, 23, were found shot to death in their Mountain City, Tenn. home on January 31.
