The Missouri State Highway Patrol confirmed Officer Gary Michael with the Clinton Police Department was killed during a traffic stop Sunday night near the Henry County Sheriff's Dept.
Police said that after shooting Michael, the suspect fled in his auto, then crashed a few blocks away. The suspect drove about three blocks before crashing his vehicle and fleeing on foot.
The Clinton Police Department has no body camera policy, but police were working Monday morning to determine if there was dashcam video from Michael's auto or surveillance video from nearby businesses, Lowe said. Authorities did not know whether he was wounded.More news: U.S. to Exempt Journalists, Aid Workers from North Korea Travel Ban
Authorities identified the suspect as 39-year-old Ian McCarthy from Clinton.
Michael returned fire, but it's not clear if he hit the suspect, who fled on foot after the crash, the sergeant said.
Police were at first reluctant to name pin the shooting on him, describing him only as a "person of interest". "(Michael) was heroic right to the end.More news: The Daily Telegraph accidentally report the death of Prince Philip
The suspect fled the scene and abandoned the vehicle.
He had been with the department for less than a year when he was shot and killed. He says the 37-year-old Michael returned fire but that the suspect got back into the vehicle and drove off before crashing two blocks away.
A manhunt was underway in Missouri Monday for a person of interest in the fatal shooting of a police officer. Authorities believe he is on foot and still in the Clinton area, 75 miles (120 kilometers) southeast of Kansas City.More news: Knifeman arrested at Eiffel Tower `wanted to kill soldier`
