Police continue searching for a motive in the shooting at an Idaho In-N-Out Burger restaurant over the weekend that left three people dead and seven others injured. The armed suspect was identified by the Twin Falls Police Department as Chad Williams, 24. Idaho Attorney General Raul Labrador thanked Salinas and the off-duty police officer for their bravery in challenging the gunman. Twin Falls is hosting a candlelight vigil at 9 p.m. Tuesday in honor of the deceased and wounded victims. The In-N-Out restaurant caught in the middle of the shooting had just opened on July 24 as part of the California-based burger chain’s expansion into Idaho.
