Suspect in Idaho shooting dies of self-inflicted gunshot wounds; probe underway

Chad Williams, 24, the suspect in the In-N-Out Burger shooting in Twin Falls, Idaho, died of a self-inflicted gunshot wound.

The shooting on Saturday left three people dead and seven injured; two wounded have been treated and released, three are stable, and two are critical.

An off-duty state trooper and an armed citizen returned fire, which police chief Matthew Hicks says helped drive the suspect away and prevent more casualties.

In-N-Out owner Lynsi Snyder confirmed that one of the deceased was an employee, and expressed mourning and support for the families.

The FBI is asking for photos or video from the shooting as the investigation continues.
