BTK: The World's Most Elusive Serial Killer

This is the story of one of the most extraordinary events in criminal history. Wichita, a small mid-American city, harbours a dark past. In the 70's, its tranquillity was shattered by a spate of brutal killings. It found that it harboured a serial killer, known as BTK, due to the method in which he bound, tortured and killed his victims. After his 7th victim, BTK disappeared and Wichita desperately fought to return to normality. Incredibly the killer resurfaced after a 25-year silence and has plunged the city into a state of panic once again.
