 Casso told investigators that the plotters decided to kill Gotti and DeCicco with a bomb in order to make the Gambinos think that Zips, or Sicilian mafiosi, were involved.Although Sicilian gangsters are notorious for using bombs, they have long been forbidden in the American Mafia since they put innocent people at risk.Casso also told authorities that Pate was selected because he had no links to the Gambino family and thus would not be recognized while staking out DeCicco.
