Houston police say that an armed man’s attempt to stop a carjacking went terribly wrong on Saturday night when he shot the vehicle’s owner in the head, then fled the scene.

According to KHOU Channel 11 News, the shooting took place around 11:15 p.m. at a Valero gas station in north Houston.

Police officials say that two men jumped the owner of a Chevrolet pickup truck and absconded with his vehicle.

As the men struggled with the car-owner, a passerby produced a gun and fired multiple shots, missing the thieves but striking the victim in the head.

The shooter quickly gathered up his shell casings from the pavement and fled the scene.

The injured man was rushed to a nearby hospital where he is currently in stable condition.

Police recovered the stolen truck about two miles from where the shooting took place. No suspects have been apprehended in the theft or the shooting.
