The Switzerland County Sheriff's Department started an investigation Saturday after finding a 91-year-old man's body in a vehicle submerged in a pond.

Richard A. Brown, of Aurora, had been reported missing Friday evening, Sheriff Roy Leap said in a news release. Police said Brown frequently visited a Switzerland County farm to fish.

Upon searching the pond on the farm, authorities found Brown's vehicle and Brown inside the car. Authorities do not suspect foul play, but will conduct an investigation to make a final determination.

The Indiana Department of Natural Resources and the Dearborn County Water Rescue Unit assisted at the scene.
