Gregory Hill, 65, was shot and killed while working as a maintenance worker at the Devon Park Apartments on Crooks Road in Royal Oak on the afternoon of Thursday, July 31, 2025. Hill, a General Motors retiree who kept the job because he enjoyed staying busy and helping people, was not part of an earlier verbal dispute in the parking lot but was nearby when the confrontation escalated. Witnesses say a tenant, identified as 32-year-old Nathaniel Joshua-Olsen Rockwell, retrieved a handgun from his vehicle and, after the other person fled, opened fire as Hill was reportedly trying to call 911. First responders from the Royal Oak Fire Department rendered aid, but Hill died at the scene.

Royal Oak police arrested Rockwell at the complex without further incident; he was arraigned on one count of first-degree murder, three counts of felony firearm, and two counts of assault with a dangerous weapon and was denied bond. Residents of the apartment complex created a memorial for Hill. If anyone saw the shooting or has information about what led to the confrontation, please share what is known with investigators.
