Multiple homes were destroyed when fire erupted at an apartment building in Nanuet.

Fannetta Glass-Miles and her husband Terry say all their belongings are gone.

"The smoke came in through the walls, the vents, everywhere," says Glass-Miles.

They were home Tuesday afternoon at their apartment off of Avalon Gardens Drive in Nanuet when smoke started billowing into their apartment and then, there was fire.

"The was a boom and flames erupted up the sides of the building," says Glass-Miles.

Moments before that, emergency officials say some kind of work was being done outside the building. At one point, contractors out there smelled gas and called 911, according to emergency officials. Shortly after that is when the fire began.

Emergency crews tell News 12, the flames spread quickly.

No one was seriously hurt. However, one dog still hasn't been found.

"The investigation is ongoing and there will be some findings from that eventually," says Town of Clarkstown Supervisor, George Hoehmann.

The damage is bad. Town leaders say the building will likely need to be torn down.

The Red Cross is offering help for families who lost everything in the fire.

So far, 10 people have registered for emergency assistance.
