This episode chronicles the decades-long investigation into the 1982 murder of Regina Reynolds, a nineteen-year-old student who vanished while hitchhiking in New York. Although detectives discovered business cards belonging to a local carpenter named Donald Sigby near the victim’s body, a lack of physical evidence prevented an initial arrest. The case remained unsolved for over twenty years until cold case investigators utilized modern DNA technology to re-examine biological samples preserved from the original crime scene. By covertly trailing Sigby to a restaurant, authorities secured his genetic profile from a discarded drinking straw, which directly linked him to the killing. This breakthrough led to a guilty verdict in 2005, finally securing a life sentence for the elderly murderer nearly a quarter-century after his crime.
