The Covina massacre was a mass shooting and arson attack that Bruce Jeffrey Pardo, 45, committed on Christmas Eve, 2008, in Covina, California, United States. Pardo, wearing a Santa suit, entered a property belonging to his former in-laws and killed nine people by shooting or by arson from the fire he started. Pardo was later found dead from a self-inflicted gunshot at his brother's residence in the early hours of Christmas Day. Police speculated that Pardo's divorce, which had been finalized only one week before the killings, was a factor in why Pardo had decided to kill his ex-wife and her relatives.
