In the early morning hours of August 13, 2014, 26-year-old Ulysse Prinso was standing outside on Cortelyou Road in Brooklyn’s Flatbush when a man stepped into the street and fired multiple shots in his direction. One bullet struck Prinso in the side of his head, causing severe internal injuries. He was taken to Kings County Hospital and died there on September 3, 2014.

High-definition surveillance video captured the shooting and showed the gunman walking away from the scene after firing. Authorities identified the shooter as 24-year-old Avon Simmons of Flatbush and tied him to the G-Stone Crips. Investigators believed the shooting was retaliatory after Simmons’s brother had been shot. Simmons was arrested, pleaded guilty to second-degree murder and second-degree criminal possession of a weapon on February 9, 2016, and was sentenced on March 10, 2016, to 20 years to life in prison for the fatal shooting.

If anyone knew Prinso, the circumstances on Cortelyou Road that morning, or has additional information about the events leading up to the shooting, please share what is known.
