Surveillance video with voiceover audio from authorities shows Williams pulling up to the In-N-Out drive through in a white Honda Civic. When he stops at the payment window, he rolls down his window and shoots employee Ashley Garibay, 23, who later died of her injuries.

He then pulls up slightly in the drive through, parks and exits his car, then shoots and kills Christopher Claunch as he’s sitting in his vehicle, according to the video.

The video then shows a man, who authorities identify as former police officer Austin James, running towards Williams before getting shot. James survived the shooting, but is shown retreating back to his car while losing blood.

Williams then returns to the payment window and observes other employees rendering aid to Garibay before firing into the window, according to the video. His handgun jams, prompting him to return to his vehicle and retrieve a rifle, according to the video.

Inside the restaurant, an off-duty Idaho State Police Trooper assists evacuating patrons and employees while searching for the gunman, according to the video. Authorities said they were not releasing the off-duty trooper’s name at this time.

The surveillance footage shows about half a dozen uniformed In-N-Out employees crawling on the ground, and over each other, to escape.

Williams then fires at fleeing patrons in the parking lot and returns to the drive-through window, where he exchanges gunfire with the off-duty trooper who’s still in the restaurant. The gunman briefly retreats, then returns to the window and fires inside again, injuring a good samaritan who was trying to help the trooper and render aid to Garibay.

A woman seen in the video fleeing from the restaurant encounters the gunman, then seeks shelter behind his car, where she finds the discarded handgun. She picks it up and then discards it when she realizes it’s jammed, according to the footage.

The gunman then walks from the In-N-Out to the street and fires at cars stopped at a red light, striking three victims, the video shows.

He then can be seen firing at Tesla vehicles parked at a nearby charging station, shooting three people as they sat in the vehicles. One of the three who were shot, Dale Schultz, 66, died from his injuries, the video states.

Williams then walks into the nearby Twin Falls Visitor’s Center, according to the footage. He then leaves the visitor center store and encounters two employees of nearby businesses on a walking trail behind the visitor center.

One of the employees engages with the gunman, talking with him and allowing others coming down the trail time to escape, according to the video. As they separate, Williams fires at the employee, the video shows.

Body camera video from police officers responding to the scene and running towards the gunman is then shown.

“Hey! Show me your hands!” an officer shouts as he points his rifle towards the gunman.

The voiceover then states that Williams fatally shot himself and fell into a canyon.

On Friday, police said that they still have not identified a motive, and that there is no reason to believe there was another shooter.

“To our victims and their loved ones, this community grieves with you,” said Twin Falls Police Chief Matthew Hicks. “We will never forget what happened here. We will never forget those that were hurt.”

The In-N-Out location opened on July 24, according to a news release from the California-based chain.

Lynsi Snyder, the president of In-N-Out Burger, addressed the shooting and the death of Garibay.

“She was taking care of our most important asset — our customers, and her life was taken by a disgusting human who doesn’t value the lives of others or his own,” Snyder said.

“He shot both on our property and off and ended his life shortly after he took the precious lives of our associate and customers, innocent people who never saw it coming,” she added.
