A Pennsylvania man killed himself after going on a shooting spree Thursday night that started at a bar, police say.

The State College Police Department received a 911 call about 10:14 p.m., reporting “persons shot” inside P.J. Harrigan’s Bar & Grill, about two miles from the main campus of Pennsylvania State University.

Police arrived to find Dean Beachy, 62, dead from a gunshot wound to the head. His 19-year-old son, Steven, died Friday afternoon at a hospital from a gunshot wound to the torso.

A third victim, 21-year-old Nicole Abrino, was shot in the chest and transferred to a hospital in Pittsburgh, where she remained Friday. Her condition was unknown.

According to police, Jordan Witmer, 21, and Abrino were sitting at the bar together when Witmer walked over to the side of the bar where the Beachys sat.

That’s when they say he took out a handgun and opened fire. Police have yet to determine what prompted the shooting.

Witmer then fled the scene and crashed his vehicle at the intersection of Waupelani Drive and Tussey Lane at 10:46 p.m. Police were notified and began to canvass the area.

At 11:09 p.m. police were dispatched to a burglary in progress with gunshots fired.

Once on the scene, authorities found the homeowner, 83-year-old George McCormick, dead from a gunshot wound to the head. They also discovered Witmer, deceased in the living room with what appeared to be a self-inflicted gunshot wound to the head.
