According to Chester Yu, Ng had instructed Tam to fire a shot in the ceiling first so that "when the people panic and get down on the floor, we will decide who to shoot." Instead, without warning, the three randomly opened fire on the patrons inside the crowded restaurant, killing five people, including two tourists, and wounding 11 others, none of whom were gang members. In Tam's confession, he stated he had been forced to join the shooting and deliberately did not target any patrons; after he "heard Melvin start shooting, then Peter. I fired my first shot at the sofa. The second I aimed where nobody was." Testimony at Melvin Yu's trial showed he was the first to open fire, using the rifle.
