THE "DR. NO" MURDERS AND THE HUNT FOR SAMUEL LEGG III

Between 1981 and 1997, a serial killer stalked truck stops and highways across the Midwest, murdering at least ten women-most of them sex workers operating in the dangerous economy surrounding interstate commerce. Known as "Dr. No" from a CB radio handle, the killer eluded capture for decades despite intensive investigation, operating with near-impunity as he selected victims from America's most marginalized populations.

In 2019, familial DNA searching finally identified the predator: Samuel Legg III, a long-haul truck driver whose neurosyphilis had rendered him permanently incompetent to stand trial. DNA evidence definitively linked him to three murders, though the full scope of his crimes may never be known.

The Shadow at the Truck Stop tells the complete story of the "Dr. No" investigation-from the first victims found along Ohio interstates to the cutting-edge genetic genealogy that cracked the case four decades later. It examines how jurisdictional fragmentation, technological limitations, and societal devaluation of sex workers allowed a serial killer to operate freely for years. Most powerfully, it reveals how the sex workers themselves identified the danger and warned each other years before law enforcement could act-knowledge that was epistemically valid but socially powerless.

This is a story about violence and survival, science and justice, memory and marginalization, and what accountability means when the killer's mind is destroyed before he can face trial.
