Modern DNA genealogy technology, which matches crime scene DNA against public ancestry databases to find distant relatives, can solve cold cases that traditional forensic methods cannot. In the 1993 murder of Sophie Sergie in Fairbanks, Alaska, investigators were unable to identify the killer despite interviewing over 500 people and collecting DNA evidence. The case went cold for 15 years until 2018, when forensic genealogists matched the DNA from the crime scene to a woman in Maine who was a distant relative of Steven Harris Downs, a former college student who had been interviewed as a suspect in 1993 but was not charged. This breakthrough led to his arrest and conviction for first-degree murder and sexual assault, demonstrating how DNA technology has revolutionized criminal investigations by enabling the identification of perpetrators who have no prior criminal record and whose DNA was never previously in national databases.
