An autopsy is scheduled to be performed Tuesday morning after a fatal car crash in Columbia County.

The Columbia County Sheriff's Office says 45-year-old Robert Jennings was traveling north on State Route 9J when he drove off the road and into a pole Sunday night around 6.

Deputies say his car then slid down an embankment and rolled over twice.

Jennings was thrown out of the car and pronounced dead at the scene.

The cause of the accident remains under investigation.
