On Dec 16, 1985 Gambino boss "Big Paul" Castellano was gunned down by John Gotti's crew. This paved the way for Gotti to take over as Boss of the Gambino Family. Castellano's execution was ingeniously planned, with each of the gunmen wearing identical hats and coats, while Big Paul and his driver, Tommy Bilotti, pulled up to Sparks Steakhouse in Manhattan.
