ELIMSPORT, Pa. - Two adults and three children were found dead Saturday inside a small cabin in north-central Pennsylvania, authorities say.

State Police Capt. David Young told the Williamsport Sun-Gazette the bodies were discovered by the owner of the 10-by-16-foot cabin just before noon in rural Washington Township in Lycoming County.

Young said the preliminary investigation showed no signs of foul play and the cause of the deaths was not considered suspicious. But state police are looking at all possibilities, including carbon monoxide poisoning, he said. A propane heater was found inside the cabin.

The two adults were identified as Jacqueline R. Stackhouse, 23, of New Columbia, and Nathan L. Reece, 30, of Muncy. Authorities did not release the names of the children - a 9-year-old girl, a 4-year-old girl, and Stackhouse's 3-year-old son. Aside from the mother and son, police did not know how the victims were related.

Authorities say the property owner, whose name was not released, hosted a get-together Friday night and slept in his truck outside the cabin before awaking Saturday and later finding the bodies.

County Coroner Charles Kiessling pronounced all five dead at the scene.
