An elderly woman was reported to be unaccounted for and firefighters were unable to fully search the home initially due to the damage.

Flames and smoke could be seen coming from the second floor of one of the two units.

The Mutual Aid Box Alarm System (MABAS) was activated to bring additional fire department resources to the scene.
