WHITEWATER, Wis. (AP) – Investigators have concluded the death of a University of Wisconsin-Whitewater student who fell in a limestone quarry this summer was accidental.  The body of 21-year-old Benjamin Fuder was found July 29 in the Whitewater Limestone Quarry in the Town of Whitewater. Fuder had been reported missing the night before after being last seen in downtown Whitewater.  The Walworth County coroner’s office ruled that Fuder fell from the rim to the floor of the quarry and that his death was an accident. He died of a head injury.  The sheriff’s office said Wednesday that it found no evidence of any criminal behavior and that it agrees with the coroner’s office.
