Muhammad, upset that he was disrespected by a (black) security guard at a motel, shot and killed him. He then decided to “take out as many white men” as he could. He shot Zackary, who was a passenger in a PG&E utility truck, before shooting Mark as he exited a Catholic Charities USA building. He then chased David into the Catholic Charities USA parking lot, before shooting him twice. He shouted “Allahu Akbar!” as he was arrested.
