(Portland, OR) -- DNA genealogy tracing has helped solve a 54-year-old Portland cold case. In 1970, a Boy Scout troop leader found remains on Sauvie Island in a grave. DNA was matched to databases, but nothing was returned. In 2018, DNA genealogy tracing was started, but the remains were still unidentified. In January 2023, DNA was uploaded into the open-source genealogy database and that led to a distant relative. More testing was done and investigators determined the remains were Sandra Young, a Portland teenager and student from Grant High School who went missing more than five decades ago. The case has been turned over the Portland Police for investigation.
