An elderly Topeka man has died after his riding lawnmower slid down an embankment, overturned in a pond and pinned him beneath it.

WIBW identified the man as 84-year-old Wilbur Johnson, who was a caretaker of the property he was mowing when the accident happened. Fire crews used a winch to free the man, who was already dead.

The Shawnee County Sheriff’s office says emergency crews were called to the scene just before 6:30 p.m. Friday. Area homeowners found Johnson after seeing him mowing along the edge of the pond earlier in the day.
