Neither Glassport police nor county police have publicly commented on the shooting yet.

Police sources told Channel 4 Action News that Piccini was coming from work around 9:30 p.m. when she went to the station to confront her husband about something. Two officers were on duty and out on patrol, so the station was locked and she couldn't get inside.

Piccini shot a tire on her husband's personal vehicle, according to the sources. One of the officers came back to the station, and Piccini's husband eventually showed up too, and Piccini shot herself in front of both officers in the parking lot, sources said.

Yellow tape blocked off a large area around the police station on Monongahela Avenue after the shooting. Officers from several police departments were seen there.
