House of Tia Toña

In the forest of Chapultepec in the capital (DF) there is an old dilapidated house that is said to be inhabited by a woman who flies into a rage when curious onlookers come to visit.  Visitors to the house have said that when she is enraged, you can hear strange noises in and around the house; you will often see a shadow pass through the windows and the feeling of being watched by someone who sends chills down your spine and goosebumps over your flesh. 
The name of the woman was “Tia Toña”, and she was a very wealthy widow who lived many, many years ago in her house by herself. She was a very kind person and to ease her loneliness, she started taking in homeless children off the street. She gave them money, food, clothes and shelter. But in spite of her charitable acts, the kids were unruly and ungrateful. They made her life impossible and one day, they banded together and decided to kill her in order to take the house and her money.
The kids carried out the murder and threw the body down in the attic. However, they were unable to live in peace because the woman’s angered spirit returned and chased them out of the house – eventually leading each to a terrible death.  From then on, the woman’s angry spirit haunted the house and continues to do so now. Kids are especially warned to stay away from the house.

There is another version of this story that I found in this Mexican newspaper:  http://www.vanguardia.com.mx7leyendasdeterrorquehanpuestoatemblaraldf-668416.html
It is all the same except for the fact that the woman is the one who kills the kids (because they misbehaved so much) only to then be driven to guilt by her actions. She locks herself in the house and has been there ever since. Flory told this story to me during a coffee date, there were no particular gestures that she used to relay it; however, she did say that when she visited the capital for the first time with her parents, her mother repeated this story to her in an effort to scare her away from wandering away from them (it worked, especially in said park).
