Suzanne Blamires, Shelley Armitage and Susan Rushworth were three women who had all worked as prostitutes on the streets of Bradford.
While police have so far found no trace of Ms Rushworth, who disappeared in June 2009, body parts belonging to the other two women have been recovered from the River Aire in Bradford.
Stephen Griffiths, from Bradford, has pleaded guilty at Leeds Crown Court to the murders.
Suzanne Blamires, 36, went missing four days before her body parts were found in the River Aire in Shipley.
She lived in Allerton, in Barkston Walk, just a few streets from Ms Armitage's home, and was reported missing by her boyfriend.
Her mother Nicky Blamires said she had been a "bright, articulate girl" who was training to be a nurse.
"Unfortunately my daughter went down the wrong path and she did not have the life she was meant to have," she said.
"She was a much-loved daughter, sister and niece and what has happened to her will haunt me to the day I die."
She added: "At the end of the day nobody deserves this.
"All these girls were human beings and people's daughters."
At her funeral, Ms Blamires' coffin was carried out to the song Angels by Robbie Williams.
On one of the wreaths on top of the hearse her mother had written: "You were always my shining star".
"Paula" who works as a prostitute in Bradford and knew Ms Blamires, described her as a "lovely, quiet girl", who had taken to drinking to try to block out what she was doing.
"Drugs made her start doing what she did," she added.
An inquest into her death heard Ms Blamires died from severe head injuries caused by a crossbow bolt.
She also had knife wounds, Bradford Coroner's Court was told
The inquest into her death has been adjourned until a later date.
Susan Rushworth, a 43-year-old grandmother, went missing just as she was starting to turn her life around, her family say.
Ms Rushworth, known as Sue or Susie, was fighting heroin addiction when she disappeared in June last year.
Her daughter Kirsty Rushworth, 20, told the BBC her mother had stopped working on the streets six weeks before going missing.
She had started seeing her grandchildren again and had been getting help to try to wean herself off heroin.
"Her face was just blossoming really. She looked so healthy," she said.
"When she stopped taking drugs, she was just like a normal mum. More of a sister than a mum. She didn't deserve to go like she did."
Ms Rushworth had two other children.
The last sighting of her was near her flat at Oak Villas, in the Manningham area of Bradford, on 22 June, 2009. She has never been found.
Shelley Armitage, 31, who disappeared earlier this year, was "a much-loved daughter and sister", detectives say.
Described as "feisty" by friends, Ms Armitage, who had drug and alcohol problems, was filmed on CCTV on the evening of 26 April. She was last seen on Rebecca Street in Bradford city centre.
Police said her disappearance was all the more unusual as she had recently bought a puppy which she adored and hated to be parted from for long.
A local market stall holder, who works near Bradford's red-light district, said she would often speak to Ms Armitage and described her as "just a normal girl".
Born and raised a Roman Catholic, Ms Armitage would sometimes go to her local church to pray, and was known to visit volunteers at its nearby community centre.
Just before Christmas she had filled in an application form for a rehabilitation programme to try to beat her drug addiction.
West Yorkshire Police started a poster appeal to try to trace Ms Armitage, who lived in Bentcliffe Walk, in the Allerton area, several weeks before Griffiths was arrested.
An inquest heard that the cause of death could not be established.
The Bradford coroner heard how detectives established that Ms Armitage was dead from a small piece of human tissue.
The inquest into Ms Armitage's death has also been adjourned, to be heard at a later date.
