Summary based on the NamUs case record (MP56930) and 13 other sources
Charlotte Ann Erdman, a 15-year-old girl from Watertown, Wisconsin, was last seen on July 18, 1974. Charlotte ran away from home that day and was believed to have been picked up by a 41-year-old long-haul truck driver based in Illinois. About two weeks after her disappearance, her family received a letter from her, postmarked in Illinois. In the letter, Charlotte assured her family that she was safe, not involved in any illegal activities, and that she would keep in touch. However, this was the last communication they ever received from her, and she has not been heard from since.

Despite the initial contact, Charlotte was not officially reported missing until May 29, 2019, leading to a significant gap in the investigation. Over the years, there have been very few clues regarding her whereabouts, and her case remains unsolved. Law enforcement continues to list her as an endangered runaway, though there is little information available about her fate after leaving home.

Charlotte was described as being between 5'7" and 5'9" tall, weighing between 125 and 165 pounds, with brown hair and blue eyes. Authorities have kept her case open, and DNA is available for potential future comparisons.
