Detective Fallon and Detective John Finnegan were shot and killed during a robbery call.
Detective Fallon and Finnigan were on patrol duty when they learned of a robbery at a tobacco shop at 1167 48th Street, Brooklyn. As they entered the shop, they were met by gunfire from the guns of three suspects who were in the middle of robbing the store. Both Detective Fallon and Detective Finnegan were killed instantly.
The suspects fled, but were all later apprehended. One suspect was acquitted. The other two suspects were convicted of first degree murder and sentenced to death. Their death sentences were commuted to life in prison by Governor Rockefeller in 1966. One suspect died in prison and the second was the state's longest held prisoner until his death in 2009.
Detective Fallon had served with the New York City Police Department for 25 years. Both detectives were assigned to the 70th Detective Squad
