Coniston massacre
The board sat for 18 days in January 1929 to consider three incidents (Brooks, Morton and Tilmouth) that resulted in the deaths of Aboriginal people, and in one more day, finished its report, finding that 31 Aboriginal people had been killed and that in each case the death was justified.
Covina massacre
The Covina massacre occurred on December 24, 2008, in Covina, a city in the suburbs of Los Angeles, California, United States. Nine people were killed, either by gunshot wounds or in an arson fire inside a house on 1129 East Knollcrest Drive, where a Christmas Eve party was being held. The perpetrator, 45-year-old Bruce Jeffrey Pardo who had entered the house wearing a Santa suit, died from a self-inflicted gunshot to the head at his brother's residence in the early hours of the morning after the attack. Authorities cited marital problems as a possible motive for the violence; reports indicated that Pardo's divorce had been finalized on December 18, one week before the massacre. Three people, including Pardo's ex-wife and his former in-laws, were initially declared missing pending identification of their bodies.
