On March 10, 2017, 39-year-old Mary Elizabeth Nieman was last seen in the Portland, Oregon, area. A white female with blonde hair and blue eyes, standing between 5'10" and 5'11" tall, her sudden absence was a cause for great concern among those who knew her. It was described as being completely out of character for Mary to leave without warning or to cease contact with her family and friends. The specifics of her activities on the day she went missing are limited, which has added to the difficulty of the investigation into what happened to her. Years passed without any sign of Mary. The silence was profound; there was no activity on her social media accounts and no use of her Social Security number since her disappearance. Before she vanished, Mary was known to visit BottleDrop locations in both Clackamas and Washington counties. These recycling centers were a regular part of her routine, and investigators hoped they might hold clues about her movements around the time she went missing. Despite these details, her case grew cold, leaving her loved ones in a painful state of uncertainty. The official report of Mary's disappearance was not made until February 2023, nearly six years after she was last seen. This delay occurred after an extensive private investigation conducted by her family failed to produce any meaningful leads. The passage of so much time before law enforcement was formally involved has presented significant challenges to the investigation. The Clackamas County Sheriff's Office is the investigating agency, but with few details available, the case remains an unsolved and distressing mystery. Her family continues to wait for answers, hoping that someone will come forward with information that could finally explain Mary Nieman's disappearance.
