Covina massacre

On Christmas Eve of 2008, a man named Bruce Pardo knocked on the door of his ex-wife dressed as Santa Claus in the suburbs of Los Angeles, California. Inside the house, 25 people had gathered to celebrate the holiday. When the 8-year-old niece of his ex-wife opened the door, he shot her in the face. He then began shooting senselessly at everyone inside the house and purposefully executed some. Then he used his homemade flamethrower to set the house on fire. After this, he drove to his brother’s house and he shot himself. He managed to kill 9 people.
