Gunman kills three, injures seven at Twin Falls In-N-Out Burger just days after restaurant's grand opening

A shooting at a newly opened In-N-Out Burger in Twin Falls, Idaho, left three people dead and seven injured Saturday afternoon, and the company's president says the attack claimed the life of a young employee who was serving customers when the gunman opened fire.

The gunman walked into a busy shopping plaza around 2:00 p.m. on August 1, 2026, carrying a long rifle and firing both on and away from the In-N-Out property. He killed three people and wounded seven others, some critically, before taking his own life near the restaurant. Twin Falls city spokesperson Josh Palmer confirmed the death toll and said hundreds of people were in the plaza at the time of the attack.

Twin Falls Police Chief Matthew Hicks addressed reporters at a news conference hours later. He did not name the suspected gunman or any of the victims, saying authorities were still working to notify families. Investigators had not determined a motive. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting local police with the case.

Fox News Digital reported that witness video showed a person dressed in black carrying a long rifle toward a white vehicle, opening both the driver's door and the trunk. It remained unclear whether the gunman retrieved additional weapons from the vehicle or what role the vehicle played in the attack.

Hicks told reporters the immediate danger had passed.

"We believe the threat to the community is over. It was a very chaotic scene."

Palmer said it was not immediately clear whether the shooter was included in the city's reported death toll of three, leaving open the possibility that total fatalities could reach four.

In-N-Out's president mourns a worker killed on the job

In-N-Out Burger President Lynsi Snyder posted a statement to Facebook Saturday evening confirming that one of the dead was a female employee. Snyder did not name the worker but described her as someone who was taking care of customers when the gunman struck.

"We lost one of our beautiful Associates tonight. 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 the gunman fired both on and away from In-N-Out property before ending his own life. Her statement made plain the personal weight of the loss.

"My heart is broken, my chest is heavy, my eyes burn from the tears I've shed."

She added that the company would stand with the victims' families and with every worker and customer who lived through the attack.

"I am no stranger to loss, but this is so incredibly tough, and my heart also goes out to all of the Associates and Customers who were there during this traumatic event."

Snyder urged the In-N-Out community to "turn to God, not in anger, but seeking comfort and strength for those who are hurting." She pledged the company would "do everything we can to learn from this situation."

Eight days from grand opening to tragedy

The Twin Falls In-N-Out Burger had opened just eight days earlier, on July 24, 2026, as part of the chain's expansion into Idaho. The restaurant sat in what Palmer described as a busy shopping plaza, a location that on a Saturday afternoon drew hundreds of people into the area. That foot traffic turned a routine weekend outing into a mass-casualty event.

Multiple victims were transported to St. Luke's Magic Valley Medical Center. A hospital spokesperson said the facility was working with law enforcement and emergency personnel as they responded to the shooting. The hospital did not release details about the victims' conditions beyond what city officials had already confirmed, that some of the seven injured were in critical shape.

Twin Falls is a city of roughly 56,000 people, about 130 miles southeast of Boise. A mass shooting at a fast-food restaurant in a midsize Idaho community is the kind of event that shatters any town's sense of safety, and it arrived at a location that had been open barely a week.

Investigators still searching for a motive

As of Saturday evening, authorities had released almost no information about the gunman. His name, age, and background remained undisclosed. Chief Hicks said investigators were working to identify the suspected shooter and determine what drove the attack. The FBI and ATF involvement suggests federal resources are being brought to bear, though officials did not specify the exact roles those agencies would play.

The names and ages of the three people killed and the seven injured also had not been made public. Authorities said they were still notifying relatives. That left the community, and the country, with a body count, a grieving company president, and very few answers.

An employee showed up to work at a restaurant that had been open for eight days. She served customers on a Saturday afternoon. She did not come home. The people of Twin Falls deserve answers, and they deserve them soon.
