COOK, Minn. (WCCO/AP) — Sheriff’s officials say a man has died after the tractor he was driving fell into a pond in northeastern Minnesota.

The St. Louis County Sheriff’s Office identified the man as 50-year-old Sheldon Sandberg of Cook, Minnesota. According to the sheriff’s office, the man had been mowing grass with the tractor next to the man-made pond when he got too close to the edge, causing the skid steer tractor to fall into the pond and trapping Sandberg underwater.

Family members attempted to rescue the driver, but couldn’t locate him.

A rescue crew later found the man at the bottom of the pond in about 8 feet of water.
