SUMMERVILLE — An argument over trespassing apparently sparked a shootout Tuesday that left a landowner dead and a member of a bear hunting party hospitalized with a gunshot wound, police said.

Investigators were trying to sort out the details of the incident near Summerville, but charges are expected, said Trooper Bruce Morris. He said at least four shots were fired.

"From what side to who, who shot first — they're going through that process to try to determine it," Morris said.

Morris said Frank N. Shaffer, 63, of Red Lion was killed after he apparently confronted a group of four or five bear hunters about trespassing or walking across the land he owns with family members.

Paul H. Plyler, 23, of Summerville was shot once and taken by a private vehicle to a hospital in nearby Brookville. Morris said Plyler was transferred to a Pittsburgh hospital but his injuries were not considered life-threatening.

Jefferson County Coroner Bernard P. Snyder said an autopsy was planned for today.
