(Milford, MA) Investigators say a two-alarm house fire in Massachusetts was sparked by a computer.
The laptop was sitting on a cardboard box in the house when it began to overheat.
The box caught fire and the old construction of the home helped the flames spread.
A teen was able to get everyone out of the house safely.
Two other homes had to be evacuated as a precaution.
Experts say computers should be turned off when they are not in use.
