tried to escape, they left the door open to their apartment. no blame of course in that panic state. however that allows the smoke from this intense fire to just billow all the way up into the building. we're told the 15th floor was pretty bad as well. completely damaged because the door to that stairwell was also open. and that is something that investigators are going to be looking into, asking these questions of why these doors which are made to close permanently, why there was an issue with those doors, actually they reminded residents to check doors to make sure they close automatically. this is a good time to do that. but again, just so much panic, so much fear for these people as they tried to escape. and the mayor talking about how they're going to give psa throughout the school systems to remind kids and adults and everybody about closing doors in order to save lives. but i want to you hear from the mayor as he talked about just reaching out to the community here, devastated by this fire.
