Hicks said an off-duty state trooper and an armed citizen — whose identities weren’t immediately disclosed — both fired back and diverted the gunman from the restaurant. “We believe their actions helped drive the suspect away from the scene, preventing further casualties,” the chief said. “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.” Hicks said detectives are working to determine Williams’ motives, and said the suspect’s family was cooperating fully with law enforcement.
