CRAWFORD COUNTY, Ind. — Divers have recovered the body of a dump truck driver after his truck fell hundreds of feet into a water-filled rock quarry in southern Indiana.

According to the Indiana Department of Natural Resources, a Mulzer Crushed Stone Inc. employee was operating a dump truck at a quarry pit near the 20000 block of Alton Fredonia Road on Tuesday when the truck slipped over the edge and dropped several hundred feet into the water below.

First responders’ search efforts were reportedly hampered due to the unstable and steep terrain of the quarry pit. Mulzer employees ended up assisting conservation officers by helping construct a temporary path that allowed access to the water.

DNR said that sonar images taken from a conservation officer’s boat confirmed the location of the dump truck underwater. The driver, however, did not surface.

Divers and a remote-operated vehicle were used on Wednesday in search of the truck driver.

DNR said the driver’s body was recovered from inside the inverted vehicle by divers shortly before noon. The dump truck was reportedly in water between 20 and 30 feet deep.
