HOUSTON -- Police say the investigation into a fatal shooting involving an officer in northwest Houston is still underway.

According to the Houston Police Department, an officer responded to a noise disturbance call around 7:35 p.m. in the 2600 block of Mayview Drive in Acres Homes. Neighbors there complained about a loud noise coming from a parked car.

The officer says when he arrived, he spoke to a witness and then approached the white Infiniti sedan in question. After a brief conversation with the driver and allegedly smelling marijuana, the officer asked the man to get out of the car.

The 39-year-old man got out but then struggled with the officer. During the struggle, the officer saw the suspect had a pistol in his waistband, police say.

The suspect managed to grab his gun, so the officer opened fire on him, shooting and killing him.

At the scene Monday night, HPD Chief Art Acevedo said he viewed the body cam video and saw nothing wrong with the officer's actions. 

"The suspect made a sudden decision, a poor decision, to resist a lawful authority that is a police officer and to actually try to take that gun out of the holster," said Acevedo. "And the presumption being if someone is trying to take that gun they are trying to shoot you so that officer made the split-second decision to defend himself."

As per standard protocol, the incident is being investigated by the HPD Homicide and Internal Affairs Divisions as well as the Harris County District Attorney's Office.
