A shooting at an In-N-Out Burger in southern Idaho on Saturday afternoon resulted in multiple deaths and injuries, according to police.

The shooter was among those killed, Twin Falls Police Chief Matthew Hicks said at a news conference. Authorities were still working to identify the shooter and determine a motive. "We believe the threat to the community is over," Hicks said, noting that officials were still notifying next of kin and had not yet confirmed exact casualty figures. He described the scene as "very chaotic."

Before the conference, Twin Falls County Commissioner Brent Reinke said Sheriff Jack Johnson reported five people had been hurt.

Witness Lane Koehn, 34, said he was stopped at a nearby traffic light when he saw a person with an AR-style rifle emerge from the drive-thru. A man with a pistol then opened fire on the shooter. Koehn witnessed an In-N-Out employee dragging a uniformed coworker, bleeding from a chest wound, across the parking lot. The employee, Koehn, and the man with the pistol remained until paramedics arrived. "She was pretty bad off, but I don't know. I hope she made it," Koehn said. Police later instructed him to evacuate as shooting continued. Koehn noted the shooter fired at least three or four rounds, and it was unclear if anyone was specifically targeted.

Video from across the street showed a person dressed in black approaching a white car with a long rifle, opening the driver-side door and trunk before reaching inside. The videographer left quickly, fearing the person might retrieve additional weapons.

Resident Haley Dodaro, 43, was in the drive-thru line with her mother when she saw people running and workers fleeing the restaurant. A traffic director informed her of an active shooter. "People were running out crying and screaming. It was very scary," Dodaro said.

The incident occurred near a busy shopping area with hundreds of people present, Hicks said. Police were interviewing witnesses and requested information from the public. Reinke said he learned of the incident just before 4 p.m., and multiple agencies responded. Authorities closed roads and advised people to avoid the area.

St. Luke's Magic Valley medical center said it was "working closely with law enforcement and emergency responders as they manage the situation."
