Police are searching for two suspects in the shooting of a security guard during a robbery outside a convenience store in southwest Houston earlier this year.

The shooting happened about 10:30 a.m. July 18 outside the "C" store at 1415 Richmond near the Montrose area, according to the Houston Police Department.

Police said the guard, whose name has not been released, had driven to the store to escort an employee of a firm that maintained an ATM inside the store. The guard sat in his company vehicle while the ATM worker went in the store.

One of the suspects walked into the store and bought something while the other stayed outside the store near the front door. Then they approached the guard. One of the suspects knocked on the driver's side window while the other pulled out a pistol. The gunman opened fire, wounding the guard.

The guard was rushed to Memorial Hermann hospital. His condition was not released, but police said he had a non-life-threatening gunshot wound.

The suspects ran away after the shooting. They may have climbed into a gray or silver small sport-utility-style vehicle and sped away.

Anyone with information about the case is urged to contact the HPD Robbery Division at 713-308-0700 or Crime Stopper at 713-222-TIPS.
