The Missouri Highway Patrol identified the officer killed in the line of duty as officer Gary Michael, 37.
Authorities in Missouri are searching for a man they believe killed a police officer Sunday night.
On Monday, authorities said his death lamented that even the most unassuming of scenarios, such as a traffic stop, puts police officers in danger.
Michael returned fire, but it's not clear if he hit the suspect, who fled on foot after the crash, the sergeant said. He approached McCarthy on Sunday night at 10.45pm at an intersection on Missouri 13 in Clinton, Missouri, for a registration violation.
'The Situation Is Bad': Tillerson Laments Sour Ties With Russia
Tillerson's comments sound at odds with those of Vice President Mike Pence, who said the president is "unified" with Congress. The pair met a day after Trump fired FBI Director James Comey over the Russian Federation investigation.
The Missouri Highway Patrol is looking for Ian McCarthy, 39, who they say is the registered owner of the vehicle involved in the stop.
Sergeant Martin said Mr. McCarthy's vehicle was found abandoned a short distance from the scene of the shooting after it hit an embankment. In July 2015, he was charged with illegal firearm possession, although the court records do not show if he received a sentence for that charge.
Video from an Everyday Convenience Store shows Mr. McCarthy driving his vehicle into the store parking lot shortly before Officer Michael was killed, the sergeant wrote. Although fatally wounded, Michael was able to return fire. "It's a tragedy for Clinton Police Department, but it's a tragedy for this community", Lowe told the station. "He was there protecting and serving, and that's what we are called to do, and he did it, and he did with heroic fashion", Missouri State Highway Patrol Sgt. Bill Lowe said.
No other details have been released at this time.
