Today's victim, Louis DeMaria, was considered by police to be a small time racketeer. That may have been true but he also may have some how been involved with Vincent Coll or his murder five days before.
DeMaria's had been shot three times and his body dumped on a road, where it was spotted by a bus driver. Oddly, earlier that day the car used for the murder was found just a hundred feet away, wrecked, with bloodstains and a pistol missing three shots. Apparently the killers tossed DeMaria's corpse out of the car and then crashed moments later. No one inspecting the car however, found the dead man.
Interestingly DeMaria's body was found amidst a number of newspaper clippings pertaining to the Coll murder. Police were unable to place the dead man in either Coll's or Dutch Schultz's gangs so were unable to say with any certainty whether his death was a result of the murder. Perhaps he was some how involved either as a spotter or as the mystery man who entered the London Chemist drug store with the "Mad Dog" only to walk out moments later when Coll's killer entered. If in fact DeMaria was involved with Coll then there are three motives for his murder.
One, he was a Coll guy who simply liked to carry around news clippings of his boss and was a natural target as all Coll guys were.
Two, if DeMaria was the mystery man then the remaining members of the Coll mob figured out that he was the double crosser who set up their leader and meted out their own justice.
Three, since DeMaria took to carrying around souvenirs of the murder chances are he was talking about it to anyone who would listen as well, perhaps bragging in his neighborhood to show that he was more than the petty racketeer the police considered him. If the killers of Coll did you use him in some capacity they probably decided that his loose tongue was liability and rubbed him out.
