Authorities are investigating after a motorist was shot while heading south on Interstate 35 in northeast Kansas.

The Miami County Sheriff’s Office said Sunday that it’s hunting for the shooter. The shooting occurred shortly before 8 p.m. Saturday. Emergency crews transported one patient to Overland Park Regional Medical Center with a lower-leg wound.

Because authorities feared a shooter was taking potshots and targeting motorists from a nearby cornfield, the highway was shut down for several miles. Authorities also conducted a manhunt.
