This episode details the 1976 cold case of Janet Stallcup, a 19-year-old nursing student who was kidnapped, raped, and murdered in Garden Grove, California. For over four decades, her death remained a mystery alongside a similar assault on a neighbor and the 1975 killing of Guadalupe McClelland. The narrative illustrates how modern Investigative Genetic Genealogy (IGG) allowed detectives to overcome the limitations of older DNA databases by building extensive family trees from distant relatives. Through this forensic breakthrough, authorities identified Terry Dean Hawkins as the predator responsible for these heinous crimes. Although Hawkins died in jail in 1977, the discovery provided long-awaited closure for the victims' families and the sole survivor. The sources emphasize that the resolution was made possible by the meticulous preservation of evidence by police over many decades.
