Beverly Ann Ozuna-Ulrich was 42 when she was last seen on October 17, 2003, in the Belle Fourche/Spearfish area of South Dakota. NamUs lists her as MP4433 and the Butte County Sheriff’s Office as the investigating agency. She is described as an American Indian/Alaska Native woman, about 5 feet 1 inch and 130 pounds, with black or graying hair, brown eyes, a pierced right eyebrow and a tattoo reading Steven on her upper arm. She may also be known as Beverly Ann Ulrich and may have been wearing a gray T-shirt and blue jean bell-bottoms.

Family members reported she sometimes took unplanned trips but normally stayed in contact, which made her silence alarming when relatives reported her missing about ten days later. She was a mother of eight, a member of the Lakota tribe and the youngest of 16 siblings; at the time she had been separated from Steven Ulrich but still returned to the home to care for her children. Searches in the Belle Fourche area, a 2008 search of a 20-acre site and a 2004 inquiry into remains found along Interstate 90 did not locate her.

Authorities later treated the case as endangered and pursued investigative leads for years; in late 2025 police announced an arrest and charges connected to Beverly’s disappearance, and officials said they would not confirm whether her remains had been found because the investigation was ongoing.
