Aug. 1 (UPI) — At least three people were killed and two injured in a shooting at an In-N-Out Burger in Idaho on Saturday, police said.

Authorities in Twin Falls responded to reports of shots fired about 2:30 p.m. in an area that included multiple major retailers and a movie theater, NBC News reported.

Videos posted on social media showed a man wearing a black shirt and carrying a large rifle in the area, Boise State Public Radio reported.

The man reportedly shot the front windshield of a parked car and later walked into the In-N-Out drive-through.

Police Chief Matthew Hicks said it was a “very chaotic scene” and confirmed the shooter was dead.

“We have literally hundreds of people that were in some way, shape or form in the area of this restaurant at the time that are being interviewed right now,” he told reporters, BSPR reported.

In a statement, Twin Falls police said roads and a nearby bridge were closed to all residents and visitors while officers responded to the incident.

“We are working to try to ascertain his identity and the motivations behind [the shooting] and we’ll be able to figure that out in the next coming days,” Hicks told reporters.

The police chief added, “Today has been a very hard day here in Twin Falls,” NBC News reported.
