Joe Martinez, 19, was killed in the early hours of September 14, 2025, on the top level of the Rivercenter Parking Garage in downtown San Antonio. Officers arrived just before 1:30 a.m.; he was found fatally wounded and pronounced dead at the scene. The Bexar County Medical Examiner ruled the death a homicide from a gunshot wound to the abdomen.

Accounts describe a confrontation between two groups that had converged on the rooftop. An altercation began when the second group arrived, a gun was produced, and a chaotic struggle followed; in that struggle the weapon discharged. An 18-year-old was taken to hospital in critical condition, and a 16-year-old was grazed and treated on scene. A firearm was recovered and detectives detained multiple people, but no arrests had been announced and many witnesses were unwilling to say who held the gun when it fired.

The concrete rooftop above East Commerce Street, the recovered gun, and the medical examiner’s ruling are fixed facts; who pulled the trigger remains unresolved. If anyone saw the groups on the garage rooftop that night or has information that could help, please come forward.
