GFD was dispatched to a reported still alarm in the 2600 block of Connecticut at about 8:45 pm on 4-26-09, while en route I was able to see the header and glow at Central and 80-94. Truck 4 And Engine 4 being first on scene advised of a fully involved house with extension to a second house. Multiple lines were advanced and the deck gun was used to knock the fire down. Crews worked the scene for over an hour and fire investigators were requested.
