(KAIR)--A Leavenworth man suffered serious injuries after he was struck by a vehicle on Interstate-29 about one mile south of St. Joseph. .

That's according to a report from the Missouri State Highway Patrol, which says a pickup truck driven by 40-year-old Joshua Lane crashed after traveling off the west side of I-29 Wednesday morning, with the northbound truck then continuing on in the median.

That's when the Patrol says 57-year-old occupant John Cheatham jumped out of the truck, into the passing lane of the interstate, where he was struck by another vehicle, which fled northbound without stopping.

Cheatham was transported to Mosaic Life Care, in Saint Joseph, for treatment.

Lane, also of Leavenworth, was not injured, although the truck struck a barrier after Cheatham jumped out.

The wreck happened shortly before 9:00 Wednesday morning.
