Munhall, Pa.—October 27, 2025— Shortly after midnight, the Munhall Volunteer Fire Company #4 responded to the 100 block of Harrison Street for a house fire. First-arriving units found a vacant duplex heavily involved.

Engine 203 established a secondary water supply and positioned in the rear via an adjacent street, gaining access through backyards and fencing. Crews from 203 Engine and 171 Engine advanced two lines for defensive operations to prevent further spread.

Firefighters remained on scene for several hours extinguishing hot spots and overhauling debris. The Allegheny County Fire Marshal’s Office is investigating the cause.
