In the 1970s, the brutal murders of sex workers in economically depressed areas of the UK spark little public interest - until a teen is also killed.

Police release phone calls and handwriting samples from a suspect. Women protest law enforcements continued inability to catch the Ripper.

As the killer continues to prey upon women, police hope that the tire tracks and a victims 5-pound note may finally lead to a suspect.

More than five years after the first attack, police finally make an arrest, setting off a media frenzy and accusations of a botched investigation.
