BEAVER — A man entered the Timberline Inn restaurant about 5 p.m. Saturday and shot another man twice in the head, according to police.

The shooter was the disgruntled ex-husband of the woman his victim had been having dinner with, Beaver County Sheriff Cameron M. Noel said in a press release.

Timothy McEnaney, of Missouri, was taken to a local hospital. He died Sunday.

Police arrested Mark Erickson of Beaver County a few hours after the shooting. They found him in a remote area of the county, Noel said.

Erickson is being held in the Beaver County Jail for investigation of aggravated murder.
