SAN ANTONIO – A 17-year-old boy is dead after he was shot in the chest early Wednesday while police were responding to reports of someone prowling through a West Side neighborhood.

The shooting happened just after 12:30 a.m. along Melissa Sue near Gilbert Garza Park.

Police said an officer was called to the neighborhood after someone reported a person prowling the block. When the officer arrived, they encountered a group of people who said they had been with the teenager earlier in the night.

According to police, the group said they left the teen behind after learning he was apparently planning to break into vehicles.

While speaking with the group, the officer heard a gunshot nearby and drove down the street to investigate.

Police said the officer found the teen on the ground with a gunshot wound to his chest. Investigators said he was wearing a ski mask and a 30-round Glock magazine was found next to him.

The teen was taken to the hospital in critical condition, where he later succumbed to his injuries.

Investigators are still trying to determine what led to the shooting and whether anyone else was with the teen when he was shot.

Police have not identified a suspect and were searching the surrounding area for anyone who may have been involved.
