What happened
Twenty-year-old Sophie Sergie was murdered in a University of Alaska Fairbanks dormitory in 1993, and the case remained unsolved for decades.
The investigation
Investigators preserved biological evidence and later used genetic-genealogy techniques to identify Steven Downs, who had lived in the same dorm at the time.
What the courts or investigators concluded
Downs was convicted in 2022 and sentenced to 75 years in prison. He has continued to pursue appellate challenges.
Why the case remains significant
The case is a major Alaska example of how preserved DNA can reopen a decades-old investigation when new genealogical methods become available.
Case context
