This is an unsolved murder with Peter Sutcliffe as a likely culprit due to his insane efforts to emulate the Ripper at this particular time and in that particular area.
This is the only newspaper report I have but it is very likely Peter Sutcliffe did this murder. The timing and MO are strong linking factors and the similarity with the murder of Margo Walls. All these crimes committed in 1980 that could have been avoided had the police chosen to confide in the person (the author) who gave them the vital information, the real Ripper’s identity. Sadly they proved that they really dont care if a few civilians become victims. Its all in the course of doing their duty.
