Luckily I sleep with Murder Machine under my pillow and have it handy. On pages 346-348 it discusses the last 48 hours of Roy's life. There are more than one possible scenarios in which Roy was killed. The one described in Murder Machine as the likely one was where Roy wass summoned by Nino Gaggi to one of Patty Testa's car shops where he meets with Nino, Anthony Senter and Joseph Testa. He removes the leather jacket he was wearing sits down and Nino Gaggi shoots him seven times in the head, then Testa and Senter put two more shots behind each ear to show their loyalty. Philip Carlo described another version according to Anthony "Gaspipe" Casso, who allegedly received the contract from Frank DeCicco after Gotti's Crew chickened out according to a FBI wiretap on Peter Gott. Casso turned Senter and Testa on Roy and brought them under the Lucchese’s where ther were eventually Made.
The chandelier was already in the trunk of Roy's car as he had removed it from his house days before to have it repaired. They just draped it over him after loading his body in the trunk of his Caddilac.
