Eve Stratford, Lynne Weedon and Lynda Farrow// Serial Killer?

In the spring of 1975, a 21 year old model and playboy promotional bunny was viciously murdered in her London flat. Six months later a 16-year-old school girl was raped and murdered after a night out with friends. Four years would go by before another young woman was brutally attacked and murdered in her own home, in 1979. In 2006 DNA would definitively link two of these murders. Was a serial killer responsible for all three?
