On Monday, Fox News posted an article about the Saturday shooting at an In-N-Out Burger in Twin Falls, Idaho.

The article reports:

Police are still working to determine why a 24-year-old gunman opened fire at a crowded In-N-Out Burger in Twin Falls, Idaho, killing three people and wounding seven others before taking his own life after taking fire from a bystander and an off-duty Idaho state trooper.

Twin Falls Police Chief Matthew Hicks said Sunday that investigators were confident Chad Williams acted alone in Saturday’s attack, but detectives had not yet established a motive or fully traced his movements before the shooting.

“We believe their actions helped drive the suspect away from the scene, preventing further casualties,” Hicks said of an armed citizen and officer who returned fire. “We want to take a moment and commend the actions of the off-duty officer and the citizen, and their heroic action to stop this incident.”

…Authorities said seven people were injured. Two remained in critical condition Sunday, three were listed as stable and two had been treated and released from a hospital.

Officials said both fired at Williams during what authorities described as a chaotic and fast-moving attack, diverting his attention from the restaurant as customers and employees fled.

When an evil person with evil intentions begins shooting innocent people, it may take minutes for the police or other authorities to arrive. An armed civilian population is the quickest way to stop the shooter.
