HARRISON, Ark. (AP) — Authorities are investigating after human remains were discovered in a ditch in Boone County.

Sheriff Mike Moore says the remains were discovered Sunday. The sheriff says his office is working with the Newton County Sheriff's Office and Arkansas State Police to identify the remains and determine a cause of death.

Moore says the remains appear to belong to a white male. An initial investigation shows that the man had died a few days before his body was discovered.

The sheriff says investigators don't yet know whether foul play is involved. Anyone with information is asked to contact the Boone County Sheriff's Office.
