Police have only described the suspects as four young, adult black males who are believed to have fled the scene in a light blue or silver Chrysler 200.
The video shows two of the suspects walking up to a vehicle and opening its trunk. The vehicle in the surveillance video does not appear to be the same one that police believe the suspects used to escape.
The victim, 38-year-old Bobby Garcia, was intervening during a crime at a southside gas station when he was shot and killed, police said.
Garcia was one of two innocent bystanders who tried to intervene. A second person chased the suspects after the deadly shooting until he felt he was in danger.
According to Houston police, the store owner was unloading merchandise in front of the store in the 13000 block of Almeda when three suspects with guns pulled up.
Garcia tried to stop the suspects. He was shot twice and died at the hospital.
The store owner was grazed by a bullet.
"I can't believe this happened," Jennifer Garcia, the victim's wife told Eyewitness News. "I got two boys and they don't know yet. They need their daddy."
Garcia owns a tire shop in a strip center adjacent to the store. He had walked over to buy drinks.
About a dozen of his loyal customers gathered at his shop to comfort his family Monday evening. They remembered him as a generous person.
"I just wanted to come show my support," said Fran Russaw.
"I'm thinking about the boys. Their daddy was their world," added Robert Felix.
Investigators say the suspects were in a light blue or gray four-door Chrysler 200.
"They took a good, family guy. Everything went wrong," Garcia's wife added. "Just give yourselves up."
