Police in the center part of the state are trying to determine the identities of two sets of human remains – one found recently, another eight months ago.

One Saturday, hunters discovered bones scattered about in the woods just off of Ridge Road in Cooke Township, Cumberland County. Investigators said the bones may have been there for at least two years. The remains were likely scattered by animals, PennLive reports.

Police in Northumberland County are still trying to determine the identity of the human remains found in April along the North Branch of the Susquehanna River near Riverside by a property owner, according to PennLive.

Forensic experts concluded the bones were that of an African-American male who had died about three months to year before the remains were found, according to the story.
