The gunman walked up to the drive-thru window four times and opened fire, killing an In-N-Out employee, police said. Hicks also praised the work of an off-duty state trooper, who shot at Williams from inside the restaurant, and former police officer A.J. He acted “heroically and unbelievably” to try to slow down the shooter, the police chief said, declining to release the off-duty officer’s name. 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.
