Serial killer Sutcliffe's five-year reign of terror claimed the lives of thirteen women.
Who were the Yorkshire Ripper's victims?
Sutcliffe's first victim was Wilma McCann, a 28-year-old woman from Chapeltown in Leeds.
The mother-of-four was killed in the Prince Phillip Playing Fields, near to her home on Scott Hall Road, on October 30 1975.
She was just 28-years-old.
Her son, Richard McCann, who still lives in Leeds has since called on West Yorkshire Police to apologise for the language used to describe some of the victims.
Mr McCann, a motivational speaker, said: "45 years ago, my mum went out drinking. If only I had known what was to come, I maybe would have held her a little bit closer for a little bit longer and told her how much I loved her.
"Because the following morning the pair of us, me and (sister) Sonia, walked to the street looking for my mum and of course we all know what happened next.
"My mum was more than just a 'good time girl' or a 'woman of loose morals', as she was described by the police."
He added: "I want the force once and for all to give some closure and apologise for the way it described some women.
"The things that were said in particular by George Oldfield [former Assistant Chief Constable for West Yorkshire Police] were about some of the victims having 'doubtful morals' and the comments about Jayne MacDonald being an 'innocent victim'. Weren't they all innocent?
"These words, to me, suggested that some lives taken were worth more than others."
Emily Jackson, the mum killed with a hammer
Sutcliffe's second victim was Emily Jackson, 42, from Churwell, near Morley.
Emily, a mother-of-three, lost her 14-year-old son Derek in a freak accident in 1969.
After this, she began working as a sex worker when husband Sydney’s roofing business fell into major financial difficulties.
She and Sutcliffe drove along Roundhay Road before Sutcliffe struck her with a hammer.
She was killed on derelict land near Roundhay Road on January 20 1976.
She was just 42-years-old.
Her eldest son Neil Jackson was 17 when he had to go and identify his mother's body.
He has since written a book about the impact her murder had on his family.
Sutcliffe's third victim was 28-year-old Irene Richardson, from Chapeltown, Leeds.
Irene, who worked as a cleaner, was killed by Sutcliffe in Soldiers Field in Roundhay Park on February 6 1977.

Chief Superintendent Ridgway of the Greater Manchester Police took charge of the investigation and recognised immediately the possibility of a link with the crimes in West Yorkshire.

Josephine, a 19-year-old building society worker, had been visiting her grandparents Tom and Mary Priestly on the night of her death.
Her grandma had been at a church party and returned home late.

'Working late to make up time before a holiday'
Sutcliffe's 12th victim was Marguerite Walls, a civil servant from Farsley village in Leeds.

She turned up Alma Road to walk the 100 yards to her residence when Sutcliffe began to follow her.
He attacked and killed her.
Her body was found on wasteland near the Arndale Centre.
'Years of missed opportunities by police'
Sutcliffe avoided detection for years due to a series of missed opportunities by the police.
He eventually confessed in 1981 after he was caught in Sheffield.
Despite his 24-hour-long confession to the killings, Sutcliffe denied the murders when he appeared in court.
In May 1981, he was jailed for 20 life terms at the Old Bailey, with the judge recommending a minimum sentence of 30 years.
More than two decades later, a secret report disclosed that Sutcliffe probably committed more crimes than the 13 murders and seven attempted murders for which he was convicted.
He died aged 74 in hospital after testing positive for Covid-19 on Friday, November 13.
A Prison Service spokesman said: “HMP Frankland prisoner Peter Coonan (born Sutcliffe) died in hospital on November 13. The Prisons and Probation Ombudsman has been informed.”
