Six bodies were found Thursday in the ashes of a home where a gunman in a Santa Claus costume opened fire during a Christmas Eve party before setting the house ablaze, police said. Three others, including the couple who own the home and the alleged gunman's ex-wife, remain missing, Covina police Chief Kim Raney said. Officers found the body of suspect Bruce Jeffrey Pardo, 45, at his brother's home early Thursday in the Sylmar area of Los Angeles. Pardo had died from a single gunshot wound to the head, Los Angeles police Sgt. Martin Guerrero said. "He was going through some type of marital problems, and we believe that this residence is a relative's residence," Lt. Pat Buchanan said.
