On May 5, 1981, Massino loyalists shot and killed Trinchera, Giaccone, and Indelicato in a Brooklyn night club. On the pretext of working out a peace agreement, Massino had invited them to meet with him at the 20/20 Night Club in Clinton Hill, Brooklyn. However, Massino's real plan was to assassinate the capos. The ambush was set in the club store room, with Salvatore Vitale and three other gunmen wearing ski masks hiding in a closet. One of the gunmen was mobster Vito Rizzuto, who came from Montreal, Quebec, Canada with another Canadian mobster to help Massino. Massino told the men to avoid shooting so that bullets wouldn't spray around the room. Massino also brought drop cloths and ropes for disposing of the bodies afterwards.
