There are new details on Wednesday's Healey Street fire in Springfield.
Fire officials said an unattended space heater plugged into an inadequate extension cord caused the fire that displaced a family of three.
The fire started in the living room of the second-floor home around 1:30 a.m. The family wasn't there.
A family of four living downstairs was able to make it out uninjured.
The upstairs area of the house has about $30,000 in damage.
The Red Cross is assisting.
