This story takes place in the city of Tijuana, Mexico.
The tragedy happened on December 22, 1951. There was a big Christmas party for children living in poverty and they were to receive gifts, food and everything that a Christmas party implies. This was taking place at a multi-purpose room located in a 3-story building; the first floor was used as a small movie theater and the third floor was the multi-purpose room, I don't know what the second floor was for.
At about 22:00, the operator of the movie theater was informed that there was smoke coming out of the multi-purpose room, and he hurried to get the people out of the theater. They could get out safely, but unfortunately the children, some local personalities and other adults, didn't.
The four emergency exits were shut, so there was only one door available to escape the fire. It was started by a malfunction of the Christmas tree, and the fire spread rapidly.
That night, about one hundred people died and probably there were as many injured attendants. There were not enough ambulances so taxi drivers helped by taking people to hospitals. Also, firefighters from National City, San Diego and Chula Vista, CA helped putting out the fire.
I had to give you the whole background before getting to the ghostly stuff. That place is still there, and some brave inhabitants dare to call it home. It looks dreadful from the outside, and once you walk in there is some kind of pressure on the chest that, unless you are familiar with the paranormal, makes it hard to remain calm.
You can still see the damage of the fire, for some reason it was never repaired. At first sight, you know that there is something extraordinary going on in that building. I visited the place and talked to some of the people who are currently living there, all of them agreed to have seen or heard strange "things" at different times of the day.
A lady who has been living at The Coliseum ("El Coliseo" is the name of the building) for the last 15 years, affirms that she has seen a bunch of children rushing to one of the rooms (the building also works as a hotel) and then disappear inside. Also, she states that sometimes at night you can hear screaming in the room where the fire started.
I tried to capture some ghosts or any evidence of what happens there but I was unlucky, however, the feeling of sadness and dread are enough evidence for me.
