The Los Angeles County coroner's office has identified six of the nine people killed when a man dressed as Santa Claus attacked his ex-wife's family on Christmas Eve.

Bruce Pardo, distraught over his divorce, shot up the home in Covina where his ex-wife and her family had gathered and then sprayed the house with flammable gas, authorities said. He was burned when the gas ignited and later fatally shot himself.

Coroner's Lt. Larry Dietz said Saturday that the office identified the bodies of the ex-wife's parents: Joseph Ortega, 80, of Covina, who died from multiple gunshot wounds, and Alicia Ortega, 70, who was shot in the abdomen.
