ORLANDO, Fla. (AP) - Authorities are investigating after they say a gunshot victim trying to drive himself to the emergency room flagged down an ambulance on the highway.
Orlando Police said the male victim got the attention of the ambulance on busy Interstate-4 on Sunday. Emergency officials took the victim the rest of the way to the hospital.
The unidentified victim is currently in surgery and is listed in critical condition.
It's unclear why he was shot. No other details were released.
