Tennessee authorities on Thursday executed a man convicted of killing his ex-girlfriend by setting her ablaze in her car in 1991. Lee Hall, 54, died by electric chair at the Riverbend Security Institution. He was pronounced dead at 7:36 p.m. The Supreme Court had denied his request for a stay. For his last meal, Hall ordered a Philly cheesesteak, onion rings, a slice of cheesecake and a Pepsi.
