Three Decade Hunt
After the BTK killer surfaced again, police received numerous tips and gathered thousands of cotton swabs of DNA related to the investigation. Detectives linked two additional murders to the serial killer; one of the victims lived down the street from Rader's house (pictured). A trail of clues led police to Rader and ended a 31-year manhunt.
