Details of Disappearance
Herr disappeared sometime in June 1976; she was living in a group home in Gresham, Oregon at the time. She was believed to have been a chronic runaway and no missing persons report was filed at the time.
In 1986, two Forest Service workers found a partial human skull, some additional bone fragments and one tooth near Government Camp off U.S. 26 on Mount Hood in Clackamas County, Oregon. The skull was not identified at the time and authorities did not learn of Herr's disappearance until 2019, when the Oregon State Medical Examiner's Office got a grant to begin DNA analysis on more than 100 sets of unidentified human remains, including the Mount Hood skull.
DNA analysis on the skull, plus genealogical research, revealed Herr as a possible identity for the skull. Police located her surviving sisters and were able to confirm the identity. Authorities have asked that anyone who knew Herr or had any information on her disappearance contact them, as they are still trying to determine the cause and manner of her death.
