Annabelle, The Cursed Doll
Over time the doll began to leave messages. The messages were left in pencil on parchment paper. The women had never owned parchment paper so its origin was as mysterious as the messages themselves. The notes usually said "help us" or "help lou". The women began rigging the apartment to check for intruders. They thought that maybe someone was tricking them, but there was no evidence of break ins. One night they came home to find blood on the doll's hand.
Finally, the women contacted a medium to talk to the doll. The doll said that she was a little girl who had died on the property who was lonely. After this, the women contacted paranormal experts Ed and Lorraine Warren. The Warrens believed the story about the little girl was trickery to gain sympathy and that Annabelle was really possessed by a demon. This belief was confirmed when Angie's boyfriend was attacked physically by some unseen spirit in the apartment. The attack left a series of deep marks on Lou's chest.
After this, a priest was called in to do an exorcism. The exorcism seemed to work and the Warren's offered to take Annabelle home with them. On the way home, Annabelle caused the car to veer off the road almost killing the Warrens. The Warrens dosed the doll in Holly Water and the activity stopped for a time. Soon after, Annabelle began to be active in the Warrens' home and they had to move her to their Occult Museum in Monroe, Connecticut. They keep a website that documents their experiences with Annabelle at http://www.edandlorrainwarren.com/. The doll has remained active since its placement in the museum and is even thought to be responsible for some deaths since that time.
