LEE'S SUMMIT, Mo. — Lee's Summit police are still searching for whoever stabbed a young war veteran to death where Highway 291 merges with I-470.
Investigators believe people saw aggressive driving that played out before 23-year-old Cody Harter was stabbed and killed Saturday night.
"You would’ve had to drive around these two men fighting. You would have seen them in the middle of the road and driven around this maroon pickup," said Sgt. Chris Depue.
Police said it was a grey, silver or light-colored car that was following Harter's maroon truck that had a lawn mower in the back.
But as road rage is the reason officials suspect the offender to have stopped, he could have pulled up next to or in front of Harter's truck.
Police are focused in on the time 7:10 to 7:45 p.m.
On Saturday, he drove to Pleasant Hill and was on his way back home to St. Joseph. Officers want to talk to anyone who was driving west on Highway 50 near Todd George Road, then up north onto 291.
They believe witness statements and additional camera or cell phone footage may help them get a good suspect description out there.
Harter served two tours in Iraq and was a member of the Missouri National Guard.
The Harter family thanking Good Samaritans who stopped, trying to help. That includes one nurse who tried to give him CPR.
"Whoever did this, you left him to die alone. He did not. He was with people. Please if you know anything don’t just let him be a number. Come forward," said Kerrie Harter, Cody's mom.
Detectives are reviewing footage from businesses right now.
