Man in Santa suit kills 8, self

Stinging from an acrimonious divorce, a man plotting revenge against his ex-wife dressed up like Santa, went to his former in-laws' Christmas Eve party and slaughtered at least eight people before killing himself hours later.

Bruce Pardo's ex-wife and her parents were believed to be among the dead. Investigators planned to return to the scene on Friday and sift through the ashes of the home, which Pardo set ablaze using a bizarre homemade device that sprayed flammable liquid.

Pardo, 45, had no criminal record and no history of violence, according to police, but he was angry following last week's settlement of his divorce after a marriage that lasted barely a year.
