Peter Sutcliffe was the newly-married former grave digger whose brutal reign of terror instilled unshakeable worry in the North of England as police failed to pick up the clues in their pursuit of the notorious murderer known as the Yorkshire Ripper. In all, 13 women were killed and seven more were viciously attacked, although police remain convinced the Yorkshire Ripper’s grim roll call of female victims remains higher. They were teenage girls, shop assistants, prostitutes, clerks. They were mothers, daughters, sisters, wives. And the broad spectrum of victims from various walks of life meant that no woman was safe with Sutcliffe at large. This is the timeline of Sutcliffe's twisted life: the attacks leading to his arrest and imprisonment and the name of every victim who had their lives brutally taken away by the killer:

The assailant’s identity went unknown for years – police were misled by a hoax which took detectives to Sunderland in 1979. A tape was sent to police by a man calling himself Jack the Ripper. He had already sent a series of hand-written letters from Sunderland and police believed they were on to the killer.

Police discounted all suspects without a Wearside accent – Sutcliffe included. By the summer of 1979, Sutcliffe had been interviewed five times. However, the fact his accent and handwriting did not match those of the hoaxer meant Sutcliffe remained a free man, allowing him to keep killing.

His next two killings were Josephine Whitaker, 19, a building society worker from Halifax who had been visiting her grandparents on the night of her death on April 4, 1979. Barbara Leach (pictured), 20, was a student who was murdered while walking in Bradford on September 1, 1979
