Robert Richardson was 22 when he was found shot on May Street in New Haven on April 7, 2016. Emergency crews arrived after a report of a man down at about 1:13 a.m.; Richardson suffered a single gunshot wound to the back of his head and was pronounced dead at Yale-New Haven Hospital at 1:50 a.m. He became the city’s third homicide victim that year.

Detectives from major crimes and forensic divisions processed the scene and spoke with local residents. Neighbors said they were awakened by gunfire, and police were told an SUV left the area with its headlights off around the time of the shooting, but no description of a shooter was reported. The investigation produced few leads and no arrests in the weeks and months that followed.

The case remains open and unsolved; Richardson’s family and friends continue to seek answers. If anyone has information about what happened that night or remembers seeing an SUV in the area, contact investigators.
