A Three Rivers Ambulance Authority Supervisor truck hit someone early this morning.  The accident happening on Breckinridge street near downtown just past 12:30.  When police got to the scene, they found the TRAA medic helping the guy out and police believe they have been able to figure out what had happened.  The man had been involved in an argument with a woman at which time he got out of the car and jumped on the hood.  When he got off the car, the woman drove away. Police believe, as the man was walking down the street, he may have jumped in front of the TRAA vehicle. He’s in critical condition right now.
