When Tina Bowen and her sister, Karen, began hearing knocking in the walls of their home in Pepperell, Massachusetts, the girls believed it was their recently deceased mother trying to reach out to them from beyond the grave. In time, however, the knocking became more intrusive and aggressive, and it was soon accompanied by objects being moved around the house and frightening messages left on the walls. After months of torment, the Bowens discovered that it wasn’t a ghost haunting their home, but sixteen-year-old Daniel LaPlante, a boy Tina had briefly dated and who’d become obsessed with her.
Daniel LaPlante was arrested and charged with various crimes, for which he was convicted and served a sentence in a juvenile detention center. Unfortunately, the court’s decision to try LaPlante as an adult meant that he was granted bail and after just one year in detention, he was bailed out and allowed to live with his mother pending trial. It turned out that brief period of freedom was all the time LaPlante needed to find a new object of his obsession and by the time the police learned of his violent intentions, it was already too late.
