Florence County Coroner Keith Von Lutcken says an autopsy on the body of Victoria Carter Redden, 51, of Lake City shows that she more than likely died from a medical condition, but he's still waiting on more tests to confirm it.
Lutcken believes Redden's medical condition contributed to her crashing her car into Forest Lake on Knollwood Road last Sunday afternoon.
Firefighters and two Good Samaritans rescued Redden from a completely submerged car.
Officials said it took crews 14 minutes to get her out of the car, which was in about 15 to 20 feet of water. She was the only person inside of the car.
Drivers in the area at the time said Redden was not speeding before the crash.
