The Missouri Highway Patrol has identified the Clinton Police Officer killed in the line of duty last night as 30-year-old Officer Christopher Ryan Morton.
Morton served as a full-time officer for the Clinton Police Department for two years beginning in 2015. Before that he was a specialist for the Army National Guard. He was deployed twice overseas, serving in Afghanistan as a bridge crew member and a radio communications manager.
Morton is the second officer killed in the small town in the last seven months. Clinton officer Gary Michael was killed during a traffic stop in August 2017.
“When I first heard about it, got that call, I didn’t believe it. The likelihood of that happening twice in such a short time span, is very tragic,” said Sgt. Collin Stosberg with the Missouri Highway Patrol.
Morton was reserve officer for much of 2017, but returned to full-time duty after Michael’s death.

In a press briefing, Sgt. Bill Lowe, of the Missouri State Highway Patrol, provided an update: "At approximately 9:20 this evening, the Clinton County 911 center received a 911 call from a residence. There were two women screaming in the background ... they (the call center) notified Clinton police department and they had officers respond to that residence."
When the three officers arrived, says Lowe, the suspect opened fire from inside the residence. "They (the officers) ended up going inside the residence in an attempt to apprehend the suspect. At that point in time, the suspect shot and killed one of the Clinton police officers and wounded two other officers," he says.
The suspect was still in the residence. According to Lowe, the Troop A SWAT team came up with a plan. "At approximately ten after midnight," he says, "the Troop A SWAT Team entered the residence and found the suspect deceased." It's unclear how the suspect died.
The names of the officers and the suspect have not yet been released. The two wounded officers, says Lowe, are being treated at area hospitals. According to KCTV5, one officer reportedly has moderate injuries and the other has minor injuries.
