Mary Elizabeth Nieman was 39 when she was last seen in the Portland, Oregon, area on March 10, 2017. She is a white female, blonde hair, blue eyes, and listed between 5 feet 10 inches and 5 feet 11 inches tall. Her disappearance was described as completely out of character; family and friends said she would not leave without warning or stop contacting them.

There are few specifics about Mary’s activities the day she vanished. Investigators noted she regularly visited BottleDrop recycling locations in both Clackamas and Washington counties and hoped those stops might help establish her movements. There was no activity on her social media accounts or use of her Social Security number after March 10, 2017. The Clackamas County Sheriff’s Office is investigating; an official report was not filed until February 2023 after a lengthy private inquiry by her family.

If anyone saw Mary around March 10, 2017, or remembers her at BottleDrop locations in Clackamas or Washington counties, please share what you know.
