Three people, including an employee, were killed in a shooting at an In-N-Out Burger restaurant in southern Idaho. This was reported by Qazaqyia.kz citing Associated Press.

In-N-Out owner Lynsi Snyder said in a statement released early Sunday on social media: "My heart is broken, my chest is heavy, my eyes burn from the tears I've shed. We lost one of our beautiful Associates tonight. In-N-Out will be mourning with the families and praying for them as they tread through a very painful season."

The FBI on Sunday encouraged the public to submit images and videos related to the shooting Saturday in Twin Falls that left seven other people wounded, some critically.

The In-N-Out had opened just about a week earlier, on July 24, as part of the California-based company's recent expansion to Idaho.

Snyder did not identify the worker. Officials were still trying to notify relatives of victims and so were not yet releasing the names, ages or other details about the people hurt in the shooting, Twin Falls spokesperson Josh Palmer said Saturday.

Police who responded to the shooting found the body of the suspected gunman in an area near the restaurant, Palmer said. He did not know if the suspect was included in the fatality count. Some of the people injured were in critical condition, Palmer said.

Twin Falls Police Chief Matthew Hicks said in a news conference earlier Saturday that police were still trying to determine the shooter's identity and motive. "We believe the threat to the community is over," Hicks said. "It was a very chaotic scene."

Another police briefing was planned for Sunday afternoon. Palmer said investigators were interviewing witnesses to the shooting. The restaurant is in a busy shopping plaza.
