In the summer of 1977, 17-year-old Elizabeth Ann Elder, known as Lisa Roberts after adoption, ran away from her home in Roseburg, Oregon. Her father reported her missing on July 25, 1977. Lisa telephoned her parents from Everett, Washington a few weeks later asking for money; the family sent funds to a local bank but the money was never claimed and that call was the last contact they had with her.

On August 9, 1977, while hitchhiking near Silver Lake in Everett, Lisa was picked up by 20-year-old David Roth. Her remains were found on August 14 by blackberry pickers; decomposition and injuries left her unrecognizable and she became known to investigators as Precious Jane Doe.

Roth was later arrested after a friend reported he had confessed, and in 1979 he was convicted and sentenced to 26 years. He died in 2015. In 2020, DNA and genetic genealogy applied to a preserved hair sample identified Precious Jane Doe as Elizabeth Lisa Roberts, allowing her remains to be returned to her family. Does anyone have memories of Lisa from Roseburg or Everett in 1977 that could add context to her last weeks?
