State Police said Thursday it's not clear how the three victims became submerged in the manure pit in Kennedyville. They were tentatively identified as 48-year-old Glen Nolt, of Peach Bottom, Pa., and his sons, 18-year-old Kelvin Nolt and 14-year-old Cleason Nolt.
Police say when the three did not come home to milk their dairy cows Wednesday evening, family members became concerned and drove to the farm.
Liquid manure was pumped out of the pit overnight during the search, and the bodies were recovered early Thursday morning.
Police say they have found no evidence of foul play.
