The 24-year-old suspect in a fatal weekend shooting at an In-N-Out Burger restaurant in southern Idaho died of a self-inflicted gunshot wound, police said Sunday.
Investigators are confident that the gunman, identified as Chad Williams, acted alone during the shooting Saturday in Twin Falls, Police Chief Matthew Hicks said at a news conference.
In all, three people died and seven others were injured at the recently opened restaurant in the southern Idaho city of about 56,000 people. Authorities said Sunday that two of the injured were treated at a hospital and released, three were listed as stable, and two were in critical condition.
