Nearby: Mother of Imperial Bar Gunman Arrested on Firearms Charges

Gloria Mazzocco was taken into custody at her residence today. 

Her son, angered by a text message while at the Fort Pitt Inn, exited the bar and re-entered with a gun—opening fire and , police said.

The incident occurred just before 1 a.m. Sunday. Patrons at the bar attempted to subdue David before North Fayette Police took him into custody. 

David was prohibited from possessing firearms—county police now claim his mother Gloria provided him with the weapon used in the shooting. 

Gloria Mazzocco is charged with conspiracy to commit firearms violation, violations of the uniform firearms act, and loaning, lending or giving a firearm to a person not to possess. 

She is lodged in the Allegheny County Jail awaiting arraignment. Her son is charged with homicide, attempted homicide, aggravated assault, reckless endangerment and weapons violations. 

David Mazzocco had no connection to any of the victims involved, police said.
