RIDGEFIELD, N.J. (CBSNewYork/AP) — Authorities say a northern New Jersey woman and her teenage son were killed when a fast-moving fire destroyed their home.

Jerlayn Scibetta, 55, and her son Daniel Scibetta, 14,  died in fire that Bergen County prosecutor John Molinelli said did not appear suspicious.

The Scibetta’s husband, an older son and that son’s girlfriend were able to escape from the Ridgefield home after the fire broke out around 5 a.m. Saturday. A town official told The Record that the husband was being treated at a hospital for undisclosed injuries, but did not disclose whether the older son and his girlfriend were injured.

It was not immediately clear what sparked the blaze, which destroyed the residence. Firefighters from Ridgefield and several nearby towns battled the blaze, which burned for several hours.

A neighbor and firefighters tried to rescue the occupants, but authorities say the flames spread too fast.
