Flames ripped through a multifamily home in Islip Terrace just after midnight Saturday, leaving 19 residents from eight apartments displaced.

The massive blaze that started in a first-floor bedroom inside the Carleton Avenue home took about 50 firefighters almost two hours to quell.

Three residents and a firefighter were treated for minor injuries.

Fire officials say there were “indications” that residents tried to put it out themselves, but helped the fire grow larger.

Neighbors who spoke with News 12 said that the home was overcrowded, an allegation that the fire marshal and the Town of Islip are investigating.

Fire crews believe an unattended candle may have been the cause of the fire.
