The three men killed were Prospect Lefferts Garden resident Marvin St. Louis, 19, Harlem resident Amadou Diallo, 27, and Flatlands resident Jamel Childs, 35, according to police. Officials did not immediately say if they suspected any of the people who were shot had opened fire at the venue.

The NYPD says 19-year-old Marvin St. Louis, 27-year-old Amadou Diallo, and 35-year-old Jamel Childs, were all shot and killed inside Taste of the City Lounge on Franklin Avenue. Detectives say Childs and Martin St. Lewis have been identified as the shooters.

Investigators believe up to four shooters were involved, and police fear the violence could spark retaliations. The attack marks the city’s second mass shooting in just weeks. FOX 5 NY's Kendall Green has the latest.
