Chris Hazencomb, of Camarillo, California, spent his 44th birthday with his mother. Four days later he was killed in the attack on the Route 91 Harvest country music festival in Las Vegas. Maryanne Hazencomb had her son taken off life support Monday. He was at the concert with a longtime friend from Las Vegas, his mother said. “He evidently saved her from getting hit so she could raise her two boys with her husband,” Hazencomb said.
