Man Testifies 2 Told Him of ‘Cotton Club’ Murder

A former supervisor of two men accused in the 1983 slaying of New York movie producer Roy Radin testified Tuesday that both men confided in him that they had “done a hit.”

Bill Rider, an ex-security chief for Hustler magazine publisher Larry Flynt who hired the accused hit men as bodyguards, said William Mentzer and Alex Marti mentioned the killing in 1983 while working at Flynt’s Bel-Air mansion. On trial are reputed cocaine dealer Karen De Layne Greenberger, 43, formerly of Sherman Oaks, and three former Flynt bodyguards: Marti, 29, of Sherman Oaks; Mentzer, 42, of Canoga Park; and Robert Ulmer Lowe, 44, of Rockville, Md. Prosecutors charge that Greenberger hired the men to kill Radin, 33, in a dispute over financing the movie “The Cotton Club.” Radin’s body was found in June, 1983, near Gorman.
