It's not yet known what sparked the fire, which broke out shortly after 3 a.m. Sunday on the ground floor of the building on Roe Street in Haledon. But officials say there's nothing to indicate it's suspicious.

The Record reports police officers and firefighters rescued some residents trapped in a house behind the building. The only exit from the house was an alleyway blocked by flames, so they helped the residents jump over a neighbor's fence.

A woman in that house suffered burns and was struck by falling embers while searching for her son. But she was treated at the scene.
