The Honolulu Fire Department released some of the 911 calls it received when a massive fire broke out at the Marco Polo building in July.

Caller: (Unit) 2613 is where my son is and he’s yelling for help.

Dispatcher: Okay, is he on the balcony?

Caller: No.

Dispatcher: Tell him go on the balcony, close the door, take a wet towel with him.

The 7-alarm fire killed four people.

Fire officials say it started in the living room of Unit 2602, but they still don’t know what caused it.

The fire is considered to be one of the most destructive in Honolulu’s recent history with damage estimated to exceed $107 million.

Many of the units are still unlivable.
