This week, Misty explains how investigative genetic genealogy helped solve the 1991 murder of Danielle Clause in Ventura, California. Using preserved crime scene DNA, GEDmatch, and advanced genealogy techniques, the team identified Larry Devon Welch more than three decades after the crime. Misty breaks down the science behind centimorgans, kinship testing, phenotyping, and how everyday DNA uploads can help solve violent cold cases.
