The 1999 execution of two Colts Neck stockbrokers, Mayir Lehmann and Alan Chalem, is now believed to have been a part of an elaborate stock scheme between the two and the Brooklyn-based Russian mafia.

The New York Daily News reported Lehmann and Chalem were allegedly murdered in a Colts Neck home by "henchman" so the mob could avoid paying the two a $5 million share from a stock scheme.

The article reports that the two were shot in the foyer of Chalem's home. Lehmann was a resident of Long Island, where he lived with his wife and five children.

The FBI is now working on a new theory that both men were targets of the killing, allegedly carried out by hired hitmen according to the Daily News.
