Bonanno associate and mob killer Harold "Kayo" Konigsberg from Bayonne, NJ died last month in a Florida nursing home just two years after getting released from a 50-year prison stint as reported by Jonathan Lin for The Jersey Journal.
Konigsberg was convicted for the 1961 murder of Teamsters official Anthony "Three Fingers" Castellito on orders from union rival Anthony "Tony Pro" Provenzano, and is suspected in many other hits from the day. The mob killer apparently admitted that he was involved with dumping the slain body of Genovese capo Anthony "Tony Bender" Strollo in a mob burial ground at a chicken farm north of Lakewood, NJ as reported in an Aug. 9, 1968 article for Life magazine.
However, in all fairness, Konigsberg did have some redeeming qualities. After all, once thrown into prison he spent the summer of 1965 dishing dirt on his mob cronies to the G-men according to an Aug. 16, 1965 FBI report which summarizes the extensive debriefing. Apparently Konigsberg hated the Mafia for squeezing him out of his financial interests -- as it had done to most Jewish mobsters by the 1960s -- and the FBI report states:
KONIGSBERG dislikes the "Mafia" in general, but principally because they took over all his financial holdings. * * * KONIGSBERG stated that he never took the oath in the "La Cosa Nostra," therefore he does not feel he owes anybody in "La Cosa Nostra" anything and would be glad to testify concerning them.
Anyone who rats on the Mafia can't be all bad.
