Summary based on the NamUs case record (MP13086) and 6 other sources
In the uncertain timeframe around 1977, a young woman named Roxanne Marie Sims vanished from Portland, Oregon. At the age of 19, with her whole life seemingly ahead of her, she disappeared, leaving behind a mystery that has endured for decades. The details surrounding the exact date and circumstances of her disappearance are scarce, a painful ambiguity for those who have sought answers. What is known is that one day she was a part of the vibrant life of the city, and then she was gone. Standing at five feet six inches and weighing approximately 125 pounds, Roxanne was a young woman with light brown, straight, shoulder-length hair. She was known to sometimes wear a large, light brown 'Afro' style wig, a distinctive fashion choice of the era.

Roxanne's personal style also included a short, multi-patched faux fur jacket and brown, wooden high-heel platform shoes, items that paint a picture of a fashionable young woman of her time. A small, possibly horseshoe-shaped scar may have been present to the side of her right eye, a small detail in a case with very few of them. Despite the passage of years, the investigation into her disappearance remains open, a testament to the enduring hope of discovering what happened to her. The Portland Police Bureau has maintained her case file, and she is registered with the National Missing and Unidentified Persons System.

The lack of concrete information has made the search for Roxanne incredibly challenging. Decades have passed without any significant leads, leaving her family and the community with unanswered questions. The vagueness of the timeline and the absence of witnesses have created a void where facts should be. This scarcity of information is a hallmark of her case, making it a particularly difficult puzzle to solve. The overview of this case is one of profound and lingering uncertainty. A young woman disappeared without a trace, and the years have offered little in the way of explanation. The hope remains that with the passage of time, someone, somewhere will come forward with the information needed to finally bring clarity and peace to the enduring question of what happened to Roxanne Marie Sims.
