Hartford, Ct 3rd alarm 7/27/15

On 7/27/15 just before 2300 hours Hartford, Ct. responded to 619 Park St for a building fire. Members had a heavy smoke condition and very difficult access to the building to locate the seat of the fire. The fire traveled the walls in the rear and the roof quickly weakened which made the fire an exterior operation. I arrived over 4 hours into the fire. Two members and 1 civilian were injured.
