(Fox News) An Iowa father and son are dead after tangling with a deadly aspect of hog farming: their manure pit. Typically situated below a barn, the manure's noxious fumes don't escape easily, and the hydrogen sulfide— along with methane, ammonia, and carbon dioxide— can be a deadly mix.
Unfortunately this proved to be the case for the second Midwest father-son duo this month when Iowa farmers Gene and Austin Opheim were repairing a pump and equipment fell into the manure pit.
Austin, 32, went into the pit to retrieve it but was quickly overcome by the fumes, and his father, Gene, 58, went in to save him, reports the Des Moines Register.
