Suspect in Idaho restaurant shooting died of self-inflicted gunshot wound, police say

Twin Falls police chief believes Chad Williams, 24, was alone in Saturday attack that killed three people

Authorities say the man accused of opening fire at a fast-food restaurant in Idaho is dead from a self-inflicted gunshot wound, as investigators say quick action by an off-duty law enforcement officer and an armed bystander helped prevent even more bloodshed.

Speaking on Sunday, Matthew Hicks, the Twin Falls police chief, said investigators are confident 24-year-old Chad Williams carried out Saturday's attack alone.
