Grand jury shows interrogation video of man on trial for fatally shooting his roommate

SAN ANTONIO – A man accused of killing his roommate told police it was an accident.

On Wednesday, jurors heard Quovante Walls describe the 2022 shooting during his police interview.

Walls is accused of murdering Mario Miller in her northwestern apartment complex.

Miller was found near the front door with a gunshot wound to the head.

Walls later told police that they had argued about money and that Miller was the one who threatened him with a gun.

“We had just gotten out of a fight,” Walls said. “I know I took the gun from him. It was an accident,” Walls said after panicking and leaving the scene.

Walls was later caught leaving the complex near Bandera Road.

While the video is playing, the detective leaves the room and when he returns, he tells Walls that he just saw surveillance video of the shooting.

In it, he said Miller could be seen walking toward the door with bags in his hand when he was apparently shot in the back of the head.

Walls said that was not his intention.

“I know for a fact that I pointed the gun at him and clearly shot him, but not intentionally,” Walls said.

Testimony in the case will continue on Thursday.

If convicted, Walls faces a life sentence in prison.
