PITTSBURGH — (WPXI) – Allegheny County Sheriff’s deputies were involved in an active shootout with a suspect at North Mathilda Street and Jordan Way in the city’s Garfield neighborhood on Wednesday. Allegheny County Sheriff Kevin Kraus told our news partners at Channel 11 that the suspect, William Hardison Sr., was pronounced dead at 5:08 p.m., nearly seven hours after the shootout started. This happened just blocks away from UPMC Children’s Hospital. Many roads were closed and people were advised to avoid the area. Multiple sources say over 100 shots were fired in the shootout. Sources said Hardison believed he was a sovereign citizen, meaning he thought he was exempt from the law. He had a criminal history dating back to at least 2000.
