The gunman walked up to the drive-thru window four times and opened fire, killing an In-N-Out employee, police said. Twin Falls Police Chief Matthew Hicks said at a news conference that investigators still don’t have a motive for the shooting. Steube said the gunman shot at him and missed. The Twin Falls In-N-Out, 130 miles (210 kilometers) southeast of Boise, the state capital, had opened in July as part of the chain’s expansion into Idaho.
