We have all heard about the boogeyman stories, “He will whisk you away if you are not well-behaved,” or so our parents said to discipline us. We never questioned who “he” was or what he looked like, but we were still terrified of him. As we grew older, we realized it was all just a myth. But what you don’t know is that mysterious things have happened to people all the time, things that could never be explained. Here are ten such chilling, unsolved mysteries that will make you wonder if the boogeyman was indeed real.

1 Catherine Hoggle, diagnosed with a schizoaffective disorder, took off with her two kids, three-year-old Sarah and two-year-old Jacob Hoggle. Her children disappeared one by one over a 12-hour period. Neither child has been seen since.

Troy Turner and Catherine Hoggle have three children. Since Catherine, their mother, was diagnosed with a schizoaffective disorder from a young age, Troy made sure the children were never alone with her. On September 7, 2014, after their eldest son’s soccer match, he dropped off the three children at their grandparents’ home along with Catherine and left for his work. Little did he know that this would be the last time he would see Sarah and Jacob.

Catherine, who was also not allowed to drive, borrowed her dad’s car with the stated purpose of taking Jacob out to get him a pizza. She returned three hours later and told her parents that she dropped Jacob off at a friend’s for a sleepover, and they didn’t question it. She then returned to her home from her parents with her eldest son and Sarah. When Turner returned home that night at midnight, he didn’t check-in with the kids as he usually did, and the next morning, he found that  Sarah, Jacob, and Catherine were missing. When Catherine eventually returned, she told him she dropped the two children at a daycare center.

Turner, soon growing anxious, wanted to bring them back home and asked Catherine about their whereabouts, but she what she said just confuses him. Frustrated with her, he decided to drive to the police station to lodge a complaint. On the way, she asked to be taken to a fast-food restaurant for a refill where she disappeared. She was found several days later and taken into custody for misdemeanor neglect and hindering charges. Because of her mental incompetency, she was put in a psychiatric hospital. She refused to reveal her children’s whereabouts and only stated that they were safe.

Over the years, her charges have been elevated to two felonies, but the court stated that they wouldn’t try people who cannot defend themselves. Her family, however, has indicated that she is faking the depth of her illness to stay out of prison. There has been no clue about the whereabouts of the children or if they are even alive. Her family suspects Catherine purposely executed this whole plan to dispose of them. (1, 2)

2 Unidentified handwritten letters terrorized the people of Circleville, Ohio, by making accusations and threats which caused one man’s death and another man’s incarceration.

In 1976, the residents of Circleville, Ohio, began receiving anonymous handwritten letters that threatened them with some invasive information. The letters were postmarked from Columbus, Ohio, but the author knew about the whereabouts of the townspeople and claimed to be watching them. The letters mainly focused on Mary Gillispie, a school bus driver, accusing her of having an affair with the school superintendent, Gordon Massie. The anonymous writer even warned Mary to end the affair and threatened her by saying he had been observing her house and her children.

Soon after, Mary’s husband, Ron, also received a letter informing him of his wife’s affair and threatening his life if he didn’t put an end to the affair. When he confronted Mary, she denied the allegations. They decided to keep it under wraps, and two weeks passed with no letters. But then, they began receiving letters again stating that if they don’t admit the affair to the school board, the writer would go public with it by broadcasting it on TV, CB radio, posters, and billboards.

In 1977, after a very infuriating phone call, Ron left his house armed with a gun. He was later found dead in his car with his gun fired, but the reason remained a mystery. When the sheriff of the town ruled the death an accident caused by alcoholism, residents began receiving letters accusing the sheriff of a cover-up. The letters continued throughout the rest of the 1970s into the 1980s. They even continued after Paul Freshour, Ron’s brother-in-law, was convicted for writing the letters and attempting to murder Mary with a rigged pistol. Paul Freshour even received one himself. The true identity of the Circleville Letter Writer remains unknown. (1, 2)
