Dairy Farmer Found Dead in Manure Pit
A dairy owner died when his tractor sank into a manure pit, Fresno County authorities said Thursday. The deceased was riding his tractor between two open pits Tuesday when the wheels apparently slipped into about 5 feet of sludge. By the time help arrived, he had been in the manure too long to have survived, Sheriff’s Lt. Mark Padilla said. His body was recovered Wednesday morning.
