The manager of an AutoZone on the city's West Side was critically wounded Monday night during a robbery at the store, police said.

The victim suffered a gunshot wound to the shoulder and was taken to University Hospital.

Police said the manager and a second employee were closing up the store at 7547 Marbach Road around 10:15 p.m. when the robber shot the manager and forced the second employee to empty the register and open a safe in the back.

The gunman stuffed the cash into a backpack and tried to shoot the second employee, but his gun jammed, police said.

"This is obviously a violent individual, and I think that it's part of our profession to take violent criminals like this off the street," said Officer Carlos Ortiz, a police spokesman.

The first officer to arrive on the scene performed CPR until emergency medical technicians took over.

"Kudos to that officer for doing exactly what is called upon when we arrive to scenes like this," Ortiz said.

An AutoZone district manager told KSAT 12 News that the store manager, a man in his 30s, is alive and stable.

The employees said the gunman is 6 feet 2 inches tall, was wearing all black and had a black bandana covering his face.

His hair was in dreadlocks.

Police don't know if he worked alone.

"If anybody has information as far as a vehicle, whereabouts, they're urged to call [the] San Antonio Police Department," Ortiz said.

The store operated under normal hours Tuesday.
