NASHVILLE, Tenn. (AP) - Authorities have identified a medic and a patient who died when an ambulance crashed on a Tennessee highway.

Nashville police say the Tennesseans were killed when they were thrown from the vehicle when it hit a rock wall Friday night on Interstate 40. Police believe the preliminary cause of the crash was excessive speed on a wet roadway.

News outlets report the patient in the ambulance who died was 36-year-old Nyema Jackson of Jackson. The medic was identified as 36-year-old Zachary Pruitt of Humboldt.

Authorities say the ambulance driver, Deborah Schichtel, sustained non-life threatening injuries. She told police the ambulance hydroplaned before it hit the wall.

At the time of the crash, the ambulance was transferring Jackson to a hospital but lost control on a curve and left the highway.
