STATE COLLEGE — A gunman at a hotel bar near Penn State’s main campus killed two men and wounding a woman, then broke into a stranger’s house and fatally shot the 83-year-old homeowner, before killing himself, authorities said.

The initial shooting happened about 10 p.m. Thursday at P.J. Harrigan’s Bar & Grill in State College, about 2 miles from Penn State’s campus. State College Police Chief John Gardner said Friday afternoon they are still trying to determine why Jordan Witmer, 21, of Bellefonte, opened fire inside the bar, shooting two men he apparently didn’t know, and Nicole Abrino, with whom he had an unspecified connection.

Dean Beachy, 62, of Millersburg, Ohio, died at the scene, and Beachy’s 19-year-old son Steven Beachy died at a hospital Friday. Abrino was shot in the chest and remains hospitalized.

Witmer then fled the bar, crashed his vehicle and broke into a home , Gardner said. Inside, he fatally shot homeowner George McCormick, 83, and then himself.
