ORIGINAL REPORT | The southbound lanes of U.S. 71 Highway at Blue River Road in Kansas City, Missouri, were closed for about five hours Wednesday due to a deadly road rage shooting.
A police spokesperson said officers were called around 11:17 a.m. Wednesday on a shooting on the off-ramp from U.S. 71 Highway to Blue River Road.
A male and a female were inside a vehicle at the time of the shooting. After the shooting, the female got out of the car and tried to flag motorists down for help. A nurse stopped, but the man inside the vehicle had already died from his injuries.
Police say two males, possibly adults or teens, fled the area after the shooting. While no witnesses saw another vehicle, police assume the males fled in a vehicle.
It is not currently known where the start of the altercation began, or where exactly the shooting occurred.

KCPD does not have any subjects of interest or a suspect vehicle identified at this time.
The southbound lanes of the highway were closed through Wednesday afternoon. Those lanes were reopened just before 4:45 p.m.
