Fire officials say they encountered heavy fire on the second floor. A roof also collapsed. Firefighters from nearby towns helped to put out the fire but not before it spread to a nearby home. Plainfield’s deputy chief says wind was a factor in the fire spreading next door.

Multiple fires have popped up within the last 24 hours in New Jersey, including two wildfires.

A relative of one of the people displaced says they believe the fire started with a spark on the electrical transmission line. The cause of the fire remains under investigation.
