Police shot and killed a man after a nearly 10-hour standoff in Beaver County that started as a domestic dispute and ended after an exchange of gunfire with police.

Police surrounded a home on Wildwood Road in Ohioville, near the Ohio border, where authorities were called about 9:30 p.m. because a man, identified as Ryan Shorak, 37, was arguing with his wife after he had been drinking, authorities said.

Mr. Shorak chased his wife from the residence, and she took shelter in a car before calling police.

“The husband was beating on the car with a gun while she was calling 911,” county District Attorney David Lozier said.

Officers safely escorted the woman from the scene. She was not injured.

Mr. Shorak fired at authorities around 11:15 p.m., and four officers returned gunfire. Mr. Lozier said that the officers who returned fire were Ohioville and Midland police officers as well as a sheriff’s deputy. No officers were injured, but a patrol car was struck by bullets.

The state police SWAT team was called soon after the exchange of gunfire and took over from local authorities when it arrived on scene.

SWAT officers tried negotiating with Mr. Shorak over the next several hours, but he did not comply, according to the DA.

“He threatened [officers] for a number of hours. They tried to negotiate with him,” Mr. Lozier said, but Mr. Shorak was never amenable.

Mr. Lozier said that Mr. Shorak told negotiators he had several weapons, including an AK-47, AR-15 and a .50-caliber handgun. Mr. Shorak was a registered gun owner, so authorities knew he had firearms, according to Mr. Lozier.

“There were rifles and shotguns by most windows,” Mr. Lozier said. “He had obviously been preparing the house for a shootout.”

Officers entered the residence about 6:50 a.m. and fatally shot Mr. Shorak. The DA said that Mr. Shorak had a handgun in his hand when he was killed.

County coroner David Gabauer was called to the scene around 7:45 a.m.

Before Mr. Shorak was killed, police had obtained an arrest warrant for him on 28 charges, including four counts of attempted homicide, four counts of a law enforcement officer and numerous other offenses.
