No foul play found in Kansas man's death at quarry

LAWRENCE | The Jefferson County Sheriff's Office says investigators found no evidence of foul play in a Topeka man's death at an eastern Kansas quarry.

Sheriff Jeff Herrig says his office has finished its investigation into the death Saturday of 52-year-old William Oaks at the Hamm's Quarry near Lawrence.

The Mine Safety and Health Administration said in a preliminary report that Oaks was cleaning hardened material on a conveyor belt's tail pulley when the conveyor belt started working. Oaks was entangled in the tail pulley. He died from internal injuries.

The Lawrence Journal-World reports that Oaks was a truck driver for the company for more than five years.
