A Maine man has been convicted in the 1993 killing of a 20-year-old woman at the University of Alaska-Fairbanks. A jury found Steven Downs, 47, of Auburn, guilty of murder and sexual assault in the death of Sophie Sergie. A break in the case occurred in 2018 when genetic genealogist CeCe Moore, of Virginia-based Parabon Nanolabs, connected crime scene DNA to the profile of Downs’ aunt who lived in Vermont.
