Newly released surveillance video traces the deadly route a gunman took through an In-N-Out Burger in Twin Falls, Idaho, and the surrounding area during last week’s shooting, which left three people dead and seven others injured.
Twin Falls Police Chief Matthew Hicks released a detailed timeline and blurred footage of the Aug. 1 attack, laying out how the violence unfolded and how an off-duty Idaho State Police trooper, a former law enforcement officer and an armed bystander moved to confront the shooter as customers and employees scrambled to escape.
Police have previously identified the gunman as 24-year-old Chad Williams and said investigators believe he acted alone. Authorities have not yet established a motive for the attack.

During Friday’s briefing, Hicks said police would avoid using Williams’ name out of respect for the victims and to keep attention on their lives and stories.
According to police, dispatchers received the first 911 call reporting an active shooter at the In-N-Out restaurant at 2:29 p.m.
The video opens with the gunman driving into the restaurant’s drive-thru, where investigators said he shot and killed In-N-Out employee Ashley Garibay. He then moved forward, stepped out of his vehicle and fatally shot customer Christopher Claunch with a handgun while still in the drive-thru area.
Former Twin Falls police officer and Idaho State Police trooper Austin James Scott, known as AJ, ran toward the gunfire and confronted the shooter, police said. Scott drew his handgun, but after suffering severe blood loss, he was pulled into a vehicle by others who began providing aid.

Police clarified Friday that Scott was not the off-duty Idaho State Police trooper who also responded to the attack, addressing misinformation that had circulated online.
The gunman then retrieved a rifle from his Honda Civic as an off-duty Idaho State Police trooper inside the restaurant helped evacuate employees and customers while searching for the shooter.
Video released by police shows the trooper and gunman exchanging fire. A bystander who tried to assist the trooper and provide aid to a victim inside the restaurant was also shot, police said.
The gunman then moved toward Blue Lakes Boulevard, where police said he shot three people who were stopped at a red light.

An armed bystander opened fire on the gunman, who ran toward a nearby Tesla charging station, according to police.
Previous News Outlet reporting identified the armed citizen as Jordan Salinas, 35, of Kimberly, Idaho. Police have said the actions of the armed citizen and off-duty trooper helped drive the gunman away from the restaurant and prevent further casualties.
At the charging station, police said the gunman shot a person inside one Tesla before shooting Dale Schultz, who died, and wounding Schultz’s passenger in a second Tesla.
The gunman continued toward the Twin Falls Visitors Center and a nearby trail as officers closed in, police said. People evacuated the visitors center, while three others sheltered inside as he entered the building.

Police said an employee later confronted the gunman on the trail, giving others time to escape.
Officers pursued him toward the canyon, where an officer found him near the edge behind a shopping center. Police said the gunman died from a self-inflicted gunshot wound and his body fell into the canyon.
Officers then returned to help victims as firefighters, paramedics and other emergency personnel provided aid.
Police said the actions of bystanders, employees and first responders helped save lives during the attack.
Investigators are still working to determine what prompted the shooting.
