Yu gave Jon the phone number of the Pacifica home and asked him to call on the following Saturday (September 3). That Friday night (September 2), members of the Joe Boys gathered in Pacifica, retrieved the weapons and put them on display. Yu received a phone call at 1:00 a.m. on Saturday morning, and after a brief, private conversation, ordered the weapons to be put back into the closet. By this time, the group plotting the shooting consisted of Tom Yu, his brothers (Chester and Dana), Melvin Yu (no relation), Peter Ng, Peter Cheung, Curtis Tam, Kam Lee, and Don Wong.
