After investigating, police found out that a bystander, unrelated to the victim or the suspect, witnessed the robbery and shot the suspect. The shooter then instructed the robbery victim to retrieve what the suspect had taken before leaving the scene.

"I was outside my apartment smoking a cigarette and I heard two gunshots go off," said Kirby Robertson, a witness.

"Yeah, I think he was justified. I would justify him. We need more people like that out here. More people to protect us out here like that," said Leroy Nortfleet, a resident in the area. 

"Hell yeah, it’s justifiable because he trying to protect the society. He's helping people. He didn’t do nothing wrong," said another resident. 

Other people said the shooting should have never happened.

Authorities are attempting to locate the individual who shot the robbery suspect. 

"When I saw and heard that he took off after he shot him, I didn’t want him to get in no trouble. He was just trying to protect a citizen," said Nortfleet. 

Houston police say the shooter later called and met with HPD detectives to provide a statement. He was released after detectives contacted the Harris County District Attorney’s Office. Officials say the shooting investigation would be presented to a grand jury.

The case details, including charge decisions, are up to the District Attorney’s office and investigators.
