Devon Powell was 23 when he was found unconscious and unresponsive near 86 Arlington Place in Mariners Harbor, Staten Island, on July 6, 2014. Emergency medical technicians pronounced him dead at the scene after he sustained a fatal gunshot wound to the head. His death was ruled a homicide by gun violence.

Police linked Powell’s killing to a violent crime spree that same morning. Investigators identified 25-year-old Tyrell Brown as a suspect in Powell’s murder and in the fatal shooting of another man, 40-year-old Kuwan Collins, less than an hour later. Brown allegedly robbed Powell at gunpoint, taking his State Benefits Card, an insurance card, and cash before shooting him.

Brown fled, carjacked a vehicle and led police on a multi-day manhunt that included a chase across the Verrazano-Narrows Bridge and ended with his capture on Staten Island after he attempted to steal a manual transmission car he could not drive. A jury later convicted Brown of the murders and he received a life sentence. Does anyone have information about Devon’s life or the circumstances around Arlington Place that could help fill gaps in the timeline?
