ME: Father, sons asphyxiated in manure

GALENA, Md. (WMAR) - Autopsies of the father and his two sons found in a farming accident have revealed that the cause of their deaths was accidental.

Doctors at the Office of the Chief Medical Examiner told Maryland State Police investigators the autopsies revealed all three victims died of asphyxia.

The bodies of Glen Nolt, 48, and his two sons, Kelvin, 18 and Cleason, 14, all of Peach Bottom, PA, were recovered yesterday from a manure pit on a dairy farm in Kennedyville, where they had been working.

Cleason Nolt had an additional cause of death listed as multiple injuries. Investigators believe his injuries were inflicted by the large propeller on the end of an auger that circulates the liquid manure in the pit.
