Gaggi was infuriated by the murder of Ragucci, and ordered DeMeo to kill Rosenberg before there were any other innocent victims. On May 11, 1979, Rosenberg reported to the Gemini clubhouse for the crew's usual Friday night meeting. Shortly after his arrival, DeMeo quickly fired a single bullet into the unsuspecting Rosenberg's head. The usually ice-cold DeMeo hesitated when the still-living Rosenberg managed to rise off the floor to one knee, but Anthony Senter then moved in and finished him off with four shots to the head.
