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 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, a number of newspaper articles pertaing to the Coll murder were found around DeMaria's body. Police were unable to place the dead man in either Coll's or Dutch Schultz's gangs so weren't able 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 possible 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 use him in some capacity they probably decided that his loose tongue was liability and rubbed him out.
Then again it could have been something else entirely.
