He was interviewed by police nine separate times over five years while continuing to kill. When he was finally caught, it was for a fake license plate — not for being one of Britain's most notorious serial killers.
Early Life
Peter William Sutcliffe was born June 2, 1946, in Bingley, England, to a working-class family. He left school at 15 and worked a series of jobs, including as a gravedigger and later as a heavy goods vehicle driver, before his crimes began. He married Sonia Szurma in 1974; the couple was unable to have children after Sonia experienced repeated miscarriages.
Early Warning Signs
In 1975, Sutcliffe carried out two non-fatal attacks on women using a hammer and knife, both interrupted by nearby witnesses before he could kill. A third attack that same year, on a teenage girl, left his victim requiring brain surgery.
The Murders Begin
In October 1975, Sutcliffe killed Wilma McCann, a mother of four, in Leeds — the first of at least 13 confirmed murders he would commit over the following five years, primarily targeting sex workers in the Leeds and Bradford areas, though several victims had no connection to sex work. His method was consistent: a blow to the head, followed by stabbing. As the killings continued, the level of violence and mutilation of victims' bodies escalated, and investigators noted the pattern reflected increasing confidence that he wouldn't be caught.
A Massive, Troubled Investigation
The case became one of the largest criminal investigations in British history, involving thousands of interviews and officers. It was significantly hampered by several factors: a hoax series of letters and an audio recording sent to police claiming responsibility under the name "Jack the Ripper," which investigators wrongly treated as credible for years and used to rule out real suspects, including Sutcliffe himself; and a marked banknote traced to Sutcliffe's workplace that investigators failed to connect to him due to the sheer number of employees who could have handled it. Sutcliffe was interviewed by police nine separate times during the investigation and was not considered a high-priority suspect, despite matching witness descriptions and being connected to both leads. The hoax letters were eventually traced through DNA testing in 2005 to John Samuel Humble, who was sentenced to eight years for perverting the course of justice.
The Arrest
On January 2, 1981, police stopped Sutcliffe while he was with a sex worker, initially arresting him for driving with false license plates. Noting his resemblance to the suspect description, they questioned him about the ongoing case. A search of the arrest location the following day turned up a knife, rope, and hammer he had discarded. After two days of questioning, Sutcliffe confessed to the murders, telling police he believed he had been instructed by God to kill sex workers.
Trial and Sentencing
Sutcliffe pleaded not guilty to murder but guilty to manslaughter on grounds of diminished responsibility, a plea the court rejected in favor of a full jury trial. In May 1981, he was convicted on all 13 counts of murder and sentenced to 20 concurrent life sentences, with a judicial recommendation of at least 30 years before parole could be considered.
Aftermath
The investigation's failures drew significant public criticism, particularly regarding police messaging that urged women to stay indoors at night rather than focusing on catching the perpetrator — criticism that fueled organized "Take Back the Night" rallies across the UK. Sutcliffe survived several assaults during his imprisonment, including one in 1997 that left him blind in one eye. In 2010, the High Court ruled he would never be eligible for release. Sutcliffe died in prison in November 2020.
