A man was seen pulling out weapons from a car before a shooting that began at an In-N-Out Burger in Idaho on Saturday afternoon (1 August).
Three people were killed, and at least seven people were injured in the incident, Twin Falls Police Chief Matthew Hicks told a press conference.
The shooter died from a self-inflicted gunshot wound, police said on Sunday.
An off-duty state trooper and a member of the public actively engaged the suspect by returning gunfire, police said.
Authorities believe that the 24-year-old suspect, identified as Chad Williams, acted alone. The suspect’s movements and motivations leading up to the shooting in a shopping area are yet to be determined, Hicks added.
