The unsolved murders of seven women from London, two of whom were from Woodford and Leyton, are belived to have been victims of the Yorkshire Ripper.

Retired police constable Chris Clark researched the unsolved murder of Gloria Booth, a woman  found strangled to death in south Ruislip in 1971, and suggests all seven unsolved killings were sexually motivated and can be linked to Peter Sutcliffe.

Pregnant mother-of-two Lynda Farrow, 30, was killed at her home in Whitehall Road, Woodford Green, on January 19 1975. Ms Farrow had been stabbed repeatedly and her head severed.

The photo fit for the suspect of the unsolved murder of Ms Farrow was a close fit to that of Peter Sutcliffe, says Mr Clark.

In an interview for BBC London news, Mr Clark said: “When you look at the image, it is Peter Sutcliffe minus then beard and moustache.”

Eve Stratford, 22, a German-born glamour model, was found dead on March 18 1975 in her flat in Lyndhurst Drive, Leyton. Miss Stratford was stabbed to death and found bound, gagged and partially clothed. 

A former Ripper investigation detective says there are striking similarities in the murders.

Andrew Laptew told BBC news said: “Some of the other similarities were very striking. The clothing of the victims had been removed, and also the bodies had been moved from the initial site of the attack.”

It is understood Sutcliffe was visiting his future wife in London and lived in Wembley in the early 1970s, when the unsolved murders took place.

The serial killer is serving life for killing 13 women and attempting to kill seven others in the 1970s.

In 2012, Scotland Yard launched Operation Yetna, a review into hundreds of unsolved murders in London dating back to the 1960s.

A statement released by Scotland Yard in 2012 read: “We are satisfied that the investigation into the murder of Lynda Farrow has been carried out in a thorough and professional manner.

“Extensive additional forensic work and analysis was conducted on this case.

"All unsolved cases are subject to regular review by the Murder Review Group and should any significant new lines of enquiry come to light they will be fully explored and investigated.”
