There was a fire that was cause by someone that had been smoking and threw it in the trash can or someone threw a lit match in the trash can.
WHO HAS THE KEYS
WHO HAS THE KEYS?!
The thing in the trash can caught fire and there was flammable things in the room and the fire was able to spread easily.
WHAT ABOUT THE WORKERS?!
The fire spread in a matter of seconds and the next thing that the workers knew was the fire was on fire with no warning.
IT DOESN'T REACH
Some workers were able to get out of the building safely and escape. Some weren't so lucky, the owners had locked the door so that the workers wouldn't steal anything or take lunch breaks.
The owner and his family had ran by going to another building through the roofs. They left the workers to die so him and his family were safe.
The firefighters were unable to let them out the building because the ladder only reached the 6th floor as they workers were at the 8th and 9th floors. They were unable to shoot water into the buildings at the fire because there were people jumping out so they were in the way.
