In October of 1972, Fred and Rosemary hired a young woman named Caroline Owens to work for them as a nanny for their children. They kept making sexual advances on her, but she declined every time. One night in December, after they both unsuccesfully tried to seduce her, she tried to leave only to be held captive overnight. When Fred threatened to let some of his friends "have" her and that he would then kill her, she complied. The next day, she was released. Though she pressed charges, Fred was able to convince the court that the acts she was forced into had been consensual, so he and Rosemary were instead only fined £50 for indecent assault. Over the next six years, they killed at least eight young women who made their way to 25 Cromwell Street as lodgers or employees together. The first was Lynda Gough, a seamstress the Wests knew personally. Next was Carol Ann Cooper, who disappeared while walking home from a movie theater. In December, Lucy Katherine Partington disappeared from a bus stop while on her way home after Christmas. She was murdered by Fred and Rosemary, who abducted her, held her captive for a week over New Year, raped and tortured her and then killed her. On January 3, Fred was treated for laceration, which is believed to have been inflicted when he dismembered Partington. From 1974 to 1979, five more women, Therese Siegenthaler, Shirley Hubbard, Juanita Marion Mott, Shirley Anne Robinson and Alison Chambers, met the same fate. It's unknown if the Wests killed more over the following years. If they did, which is not improbable, the bodies weren't buried on their property. Some girls are known to have been abducted, raped and then let go.

While committing murders, Fred also sexually abused Anne Marie West, his daughter from his relationship with Rena Costello. She eventually became pregnant, but the pregnancy had to be terminated because it occured in her fallopian tube. When she left home, he started abusing Heather West, who was conceived by Rosemary and possibly her own father, and one of his own daughters, Mae West. Fred disposed of the victims by burying them under the garage of the house or in the garden. To cover up the frequent burials, he pretended to be doing regular home improvement. In order to afford the supplies needed, he frequently stole and fenced the loot. Even though he was often brought to the police's attention for this reason, his killings went unnoticed. The couple came close to being exposed in 1986, when Heather told her friends about the abuse she suffered. In June of the next year, Fred and Rosemary strangled her to death to silence her. She was then dismembered and buried in the garden. The Wests were finally exposed in May of 1992, when Fred videotaped himself raping one of his daughters. When she told her friends, one of them reported the Wests to the police. The investigating officer, Hazel Savage, had heard of Fred while he was in a relationship with Rena Costello. When another girl raped by Fred came forward, the police obtained a search warrant. In August, they searched the house for evidence of child abuse. Fred was arrested for rape and sodomy of a minor and Rose was arrested as an accomplice. While they were being processed, their younger children were placed in the care of the government.

While Fred was in custody, Rosemary became depressed and even attempted suicide once, but was saved by one of her sons. Unfortunately, the rape case fell apart when the victims backed out. Meanwhile, Savage became increasingly suspicious of the Wests' past, the disappearance of Heather and the results of the interviews of the West children, especially that they had been threatened by Fred that they would be buried under the patio like Heather. She was able to obtain another search warrant to have the property dug up. The task was simplified when Fred confessed to Heather's murder in custody. When human bones started cropping up, Fred confessed to having committed the murders alone in order to protect Rosemary. However, he would not admit to raping any of his victims, saying they had wanted to have sex with him. Soon enough, the bodies of Anne McFall and Charmaine West turned up as well. Seeking to protect herself, Rose cut off all contact with her husband. On December 13, 1994, he was charged with a total 12 murders. On New Year's Day, he hanged himself in his cell at Winson Green Prison with a knotted bedsheet. His body was cremated and his funeral unattended except for five of his children. Rose was also put on trial in the end, first for rape but then for murder as well. She never confessed to any murders and the evidence against her was largely circumstantial. An important witness was Janet Leach, Fred's appropriate adult, who revealed that Fred had told her that Rose had been involved in the murders and even killed Charmaine West and Shirley Robinson on her own. On November 22, 1995, Rose was found guilty of 10 murders and sentenced to life. She will be never released. Though she maintains her innocence, she announced in 2001 that she will not try to appeal her conviction. In 1996, 25 Cromwell Street was completely demolished and the site turned into a pathway.
