On the morning of March 28, 2017, 19-year-old DaJour Riley was shot inside a vehicle at the intersection of Garfield Avenue and Union Street in Jersey City. The daytime shooting took place about 11:45 a.m.; Riley sustained multiple gunshot wounds and was privately transported to Jersey City Medical Center. He was pronounced dead at approximately 2:30 p.m. that day.

The Hudson County Prosecutor’s Office, assisted by the Jersey City Police Department, identified two suspects and charged them in connection with Riley’s death. Vernell Mohammed, 19, and Dashawn Mixson, 20, both Jersey City residents, were charged with murder, conspiracy to commit murder, and two weapons offenses. Mohammed was arrested days after the shooting; Mixson, who had been sought as armed and dangerous, subsequently turned himself in and was arrested without incident.
