This is a very popular urban legend here in the Philippines. This was made even more popular when the book, True Philippine Ghost Stories, published the story. Now whether you believe the story or not, is up to you. I will try to retell the story here as much as I can.
Mary Cherry Chua was a young high school student in a prestigious all-girls school here in Manila. She was very well-known in her school because she was not only pretty, she was also very smart and kind. She also came from a rich family. In short, she was Miss Popular in her school. In the stories, she was described as a young girl with long black hair, creamy white skin, chinky black eyes, and was always smiling.
One day, Mary Cherry had to stay late in school because of an activity. It was near dusk already when she said goodbye to her classmates. Later that night, the frantic parents of Mary Cherry called her classmates one by one asking if they had seen their daughter, since the girl has not arrived home yet and this was very unusual since Mary Cherry diligently goes home after school. However, not one of Mary Cherry's classmates were able to say where she was.
The following morning, Mary Cherry's body was found behind a shrubbery in the school's spacious yard. She was strangled to death with her own necktie, her skirt all the way up to her chest and her panty was found below her ankles: clear indication that she was raped. Her mouth was still open, evidently she struggled for breath as her assailant choked her. Her grieving, outraged parents of course cried justice for their daughter. It was a huge scandal at that time. The school had to do damage control because what happened would not only put a black mark on the name of the school, if they wanted to keep their students (which I mentioned were all girls), they have to catch the culprit and they have to do it fast.
It was the school's good luck that the rapist went forward on his own accord. It turned out to be the school janitor who was recently fired because of being caught sleeping on the job. He decided to rape a student because he knew that it will reflect negatively on the school and he just chose Mary Cherry because she was the one of the most popular girls there. He felt really guilty after doing his crime and since his conscience continued to plagued him, he decided to surrender. The janitor was put into prison and to serve as a token to Mary Cherry's memory, the school administration erected a stone bench on the exact spot where her body was found with the words "In Memory of Mary Cherry Chua" engraved on it.
However, the story doesn't end there. According to the students of that school, those who dared to sit on that bench will be possessed by Mary Cherry Chua. She will be made to feel how Mary Cherry felt during her last minutes in the world. Some of those who happens to pass that stone bench during dusk sometimes sees a figure of a young girl, crying nearby, perhaps crying because her bright future was taken away from her.
