There's another "version". It's said that Mary was a normal girl, but she had a disease which could spread easily, so her father being a doctor, what he did was BURY MARY ALIVE. He drugged her so as they burried her, she wouldn't be frantic. The doctor attatched a string ti her arm which was attached above the ground to a bell so that if ever Mary woke up, the bell would ring. The next day, the father/doctor came to visit the grave and found the bell on the floor. Shocked, he dug through the soil. He was shocked at what he saw! Mary was so bloody cause she probably forced herself out of the coffin. He saw she HAD NO NAILS and saw them stuck on the cover of the coffin, as if she was scratching her way out. She became all bloody cause of that. Hence forth: Bloody Mary. Hahaha.
