A three-alarm fire destroyed a Roslyn home Saturday, leaving a family to pick up the pieces and mourn the loss of a pet.

The house on Jefferson Avenue was boarded up after the fire.

Firefighters say the flames shot up the side of the house when they arrived at the single-family home at 6 p.m.

The flames moved so fast that it was quickly upgraded to a second, then a third-alarm fire.

Fire officials say one person was in the home at the time and was able to get out safely. However, a dog died in the fire and another is listed as missing and feared dead.

About 17 departments responded to the fire which officials say took about 90 minutes to put out.

They say the home is a complete loss.

Firefighters say gusty winds contributed to the high volume of fire and spread it quickly.

"The high winds definitely played a factor. As the chief had stated, they had some high winds blowing right down this hill. Thankfully, it didn't catch any other structures in the vicinity. Our fire departments did a great job of keeping it the house of origin," said Nassau County Fire Marshal's Office Chief Michael Uttaro.
