A gang of 11 men set out on a meticulous 18-month quest to rob the Brinks headquarters in Boston, the home-base of the legendary private security firm.Even as the authorities spent years trying to figure out who was behind the "great Brinks robbery," the 11 were falling out among themselves. Eventually, someone associated with the mob allegedly hired a hit man to kill Joseph "Specs" O'Keefe, a gangmember who had been grousing that he had been cheated of his proper share of the robbery.By 1957, most of the gang had been sentenced to life in prison, except for O'Keefe who got four years.
