In one of the most significant CSI developments of the 20th Century, British investigators caught and convicted a murderer using DNA screening for the first time. Colin Pitchfork raped and murdered 15-year old Leicestershire schoolgirls Lynda Mann in 1983 and Dawn Ashworth in 1986. Find out how similar DNA techniques helped close a notorious Kansas cold case 20 years later, as the sadistic ‘Bind, Torture, Kill’ murderer Dennis Rader was finally brought to justice.
