LANCASTER – The Lancaster County District Attorney’s Office has filed charges of criminal attempted homicide, aggravated assault, aggravated assault against a law enforcement officer, and other charges against a Lancaster man involved in an officer-involved shooting incident in Lancaster. 40-year-old William O’Neill of the 100 block of Hershey Avenue stands charged with the crimes. He remains in critical, but stable condition at a local hospital under guard. On Wednesday, November 29 at 4:40 a.m., Lancaster Police were dispatched to O’Neill’s residence for a request to remove a man causing a disturbance. Officers arrived and heard a gunshot before encountering O’Neill brandishing an AR-15 rifle in the side yard area of the residence. O’Neill raised the rifle and shot in the direction of the first-arriving officers. The officers yelled multiple commands to drop the rifle, which he refused. Three officers fired their weapons, hitting O’Neill and causing him to fall to the ground. Lancaster County District Attorney Heather Adams will review the incident and make a formal determination at a later date regarding police use of force.
