Bossier Parish Deputy Sheriff Harlan Dredge responded to a call on Sligo Road of a man calling for help at about 3AM.
When he arrived at the scene, he heard the cries and realized they were coming from the bayou that runs beside the road.
Thomas Hart lost control of his car in the rain and ran into the bayou and was trapped in 18 ft of water. Dredge jumped into the bayou and pulled the man to safety.
A spokesman for Willis Knighton Pierremont said that Hart's core body temperature was down to 75 degrees when he arrived there.
Good job, Deputy Dredge!
