Mark R. Miscavish, who retired from the state police in 2011 after 15 years, killed Traci A. Miscavish at the County Market in Philipsburg, according to authorities.
Investigators said Mark Miscavish began searching the store for her after arriving there around 10 a.m. He found her in an upstairs office, shot her, and then killed himself. Authorities recovered the weapon, but did not specify how many times it was fired.
Mark Miscavish was arrested Jan. 23 after Traci Miscavish, who had recently left him, returned to their home to retrieve some belongings, officials said. She thought her husband had been abusing prescription drugs, and when she went to take them away, investigators say he wrestled her to the ground, pinned her arms behind her and attempted to bind her with duct tape.
He then reportedly pulled out a gun and threatened to kill her, though a police affidavit says he did not point the gun at her. That's when a passer-by saw him trying to drag her back into the home and stopped to help. He spent a week in jail for assault, terroristic threats and harassment, before being bailed out.
Centre County District Attorney Stacy Parks Miller said Traci Miscavish lived in fear of her 51-year-old estranged husband.
"She said, 'The next time I see him is going to be at the end of a gun,'" Parks Miller told The Associated Press. "We were very concerned when he got out and we're just devastated now."
Traci Miscavish, 49, filed for divorce within the past week. Her sister Gina March, speaking to reporters outside the supermarket after the shooting, said the system had failed both her sister and her brother-in-law.
