Jam Master Jay's business partner says he grabbed a gun and sought whoever had killed the rap star
Rap legend Jam Master Jay lay, mortally wounded, on his studio floor. Dashing in from an adjoining room, Randy Allen took in the bloody scene, grabbed a gun and charged outside to seek whoever had done it, he testified Tuesday at a federal murder trial over the October 2002 shooting of the Run-DMC star in the New York borough of Queens. Allen was the last to testify among five prosecution witnesses who say they were in various parts of the studio when the turntable titan, born Jason Mizell, was killed.
