TWIN FALLS, Idaho — A bystander’s quick thinking potentially saved lives during a shooting at an In-N-Out Burger last Saturday. Witness Lane Koehn, 34, was stopped at a light near the fast-food restaurant when he noticed a person with an AR-style rifle emerging from the drive-thru. Bullets hit a car in front of him, and he saw the shooter moving towards his vehicle.

Koehn, speaking to NBC News, stated, “I could tell he was trying to figure out where to go, and somebody in the drive-thru line with a handgun was shooting at him.” The shooter appeared “panicked,” moving erratically. Koehn believes the armed bystander diverted the gunman’s attention, allowing others to flee.

The shooter was solely focused on him, and [it] allowed us to get out. The car directly ahead of me was getting shot — it gave them time to leave, Koehn said.

Koehn mentioned the incident he witnessed lasted approximately 10 to 15 minutes. Authorities have not disclosed identities of the bystander or the shooter. Twin Falls Police Chief Matthew Hicks reported three fatalities and at least five injuries from the shooting.

The gunman is deceased, though it’s unclear if included in the provided death toll. Investigators pursue insight into the shooter’s motive.

Koehn described chaos before police arrived. He managed to park near the In-N-Out where he saw an employee aiding a co-worker with a chest gunshot wound.

She was just screaming and screaming her name, telling her, ‘Wake up.’ … She was in and out of it, Koehn recalled.

A retired EMT nearby offered help until an ambulance swiftly evacuated the victim. Reports indicate the victim received aid promptly.

Lynsi Snyder, In-N-Out Burger president, confirmed a worker was among those killed. Uncertainty remains if Koehn encountered the same employee receiving aid. “She was caring for our most important asset—our customers—and her life was taken by someone who doesn’t value life,” Snyder commented.

Following the shooting, the Twin Falls Police Department reassured the community of ongoing law enforcement services. Collaborative assistance is being provided by the Twin Falls County Sheriff’s Office, local police departments, and Idaho State Police. The FBI has also set up a digital tip line inviting public submissions of any media from the incident to aid in investigations.
