The wounded security guard was then transported to a hospital, where he later died.
Officials say witnesses saw an unknown black male running eastbound from the location and towards I-45. A vehicle, possible Ford Expedition, was also seen fleeing from the area.
According to an official with Houston police's homicide division, the injured security guard was not a law enforcement officer but rather a commissioned security officer.
It is unknown why the suspect shot the security guard.
