NEW BETHLEHEM, Pa. (AP) — Officials say a western Pennsylvania hunter died when an all-terrain vehicle rolled on top of him as he tried to retrieve a deer he’d killed.

Police say another hunter discovered 53-year-old Mark Stawinski in Mahoning Township, Armstrong County on Saturday.

Investigators say Stawinski, of Buffalo Township, Butler County lost control of the ATV while descending a hill. The Armstrong County coroner’s office says Stawinski suffocated under the weight of the ATV.
