“The gangsters of the Hartley Mob, who made their rendezvous in the dives around Broadway and Houston street, were attracting much attention by using a hearse and carriages to transport their plunder through the streets. The vehicles proceeded like a funeral, with the stolen goods concealed behind the black drapings of the hearse and on the floors of the carriages, in which rode the gangsters heavily armed and dressed in funereal garments. The Hartley Mob chieftains also employed the hearse to haul their battlers. Once some twenty members of the gang set out to avenge an insult which had been offered to them by one of the Five Points gangs, and the latter gathered in force in Mulberry street to repel them. But the Five Pointers divided their ranks to permit a hearse and funeral carriages to pass, and were surprised and overwhelmed when the Hartley Mob thugs suddenly swarmed out of the vehicles and attacked them.”
