Peter Sutcliffe killed thirteen women and left seven others for dead. He committed his first known assault in Keighley on the night of 5 July 1975. He attacked a 36 year old woman who was walking alone, striking her unconscious with a ball-pein hammer and slashing her stomach with a knife. Disturbed by a neighbor, he left without killing her.
On 30 October Wilma McCann was not as “lucky” as Sutcliffe’s first victims, and he was able to carry out his attack without interruption: her battered body was found yards from her home within hours, yielding semen samples which became the starting point of the mountain of evidence that would eventually be compiled, during the search for the ripper.
6 years and at least 12 victims later, on 2 January 1981, Sutcliffe,was arrested whilst in a car with a prostitute, Olivia Reivers, when police ran a check on the car’s licence plates and found them to be false.
The hearing for Sutcliffe’s appeal against the ruling began on 30 November 2010 at the Court of Appeal. It was rejected on 14 January 2011. On 9 March 2011, the Court of Appeal rejected Sutcliffe’s application for leave to appeal to the Supreme Court.
