Trooper Brian Smith was Questioned before Going on Shooting Spree

SOUTHLAKE

Just hours before he went on a shooting spree that left two people dead last month, a former Utah state trooper was questioned by Southlake police and learned he’d soon be arrested on burglary and robbery charges, according to police documents released Thursday.

Brian Gamble Smith, 37, shot himself early Dec. 23 in Garland during a standoff with police that followed three shootings on Interstate 635 in Dallas and a shooting and pharmacy robbery in Garland. He died the next day.

The documents released Thursday detail Southlake police officers’ investigation into a Dec. 17 mugging and a Dec. 22 vehicle burglary. Detectives connected Smith to crimes after a witness to the vehicle burglary wrote down his license plate number.

Southlake Detective Richard Anderson interviewed Gamble about the burglary about 12:45 p.m. Dec. 22, about two hours after it was reported, according to the documents.

Gamble was cooperative and "very calm" at first, denying any involvement, Anderson wrote in his arrest warrant affidavit. After about half an hour of questioning, Smith grew "irritated" and said he wanted to end the interview, Anderson wrote. Anderson agreed but told Smith he was going to obtain a warrant for Smith’s arrest later that day.

Anderson then walked Smith to the police department lobby and asked him to wait so Anderson could give him a business card. When Anderson returned, he told Smith he had surveillance video showing Smith committing the burglary, according to the affidavit. Anderson also said the video showed a woman in the car and asked if she was Smith’s wife. Smith said the woman wasn’t his wife but declined to identify her and asked to stop the interview.

Anderson then walked Smith to the parking lot, the affidavit states.

About 5:30 that night, a man identified himself as Brian Smith and said he needed to refill a prescription, then produced a handgun and stole OxyContin from behind the counter of a Kroger pharmacy in Garland. By 6 p.m., four shootings had been reported in the area and two men were dead.

Smith left the Utah state troopers after an investigation that found he was abusing prescription drugs and alcohol. The investigation was prompted by a January 2008 incident in which he threatened to commit suicide.
