Tomas Campos-Cortes, 41, was shot in the parking lot of The Renwick Apartments, 6768 Renwick Drive in southwest Houston, on February 3, 2014. He and another man, David Campos-Zacarias, had been drinking by their truck when an unknown person or persons approached and shot them. David died at the scene; Tomas was taken to Ben Taub General Hospital and later died of his wounds. Authorities suspected the attack may have been a robbery and described a person of interest as a Hispanic male about 5 feet 10 inches tall, wearing a white t-shirt and a baseball cap.

Who in the area that night might have seen the truck, the men, or the person in the white t-shirt and baseball cap?
