The body of Paul Castellano lies covered with a sheet after he was gunned down on a New York City sidewalk. Castellano, the boss of the Gambino crime family in the late 1970s, was killed by a faction within his own family led by John Gotti, who felt Castellano had disrespected the Mafia by focusing on white-collar crime and by not attending the wake of a senior Gambino figure weeks earlier.
