Date of Death: Nov. 6, 1975
Manner: Leonard was found shot to death inside Thomas King's car, reportedly to divert attention from the disappearance of King.
Boston Globe reporters Kevin Cullen and Shelley Murphy allege in their book that Bulger, who at the time was a new FBI informant, told John Connolly that King killed Leonard. After reportedly changing his story two more times, the reporters claim Bulger told Connolly he heard King had been "taken out."
