  Police firmly believe the Wests were responsible for further unsolved murders and disappearances. They believed they committed ten murders between 1971 and 1979, at least seven of which were for sexual purposes. Following the rash of murders between 1973 and 1975, Fred and Rose are not known to have committed any murders until 1978. They committed one further murder in 1979, followed by an eight-year lull until they murdered their daughter in 1987. Police do not know of any further murders they committed before their 1994 arrest, although Fred confessed to murdering up to 30 people, indicating up to 18 other undiscovered victims.
  
  Fred's remarkably relaxed, emotionally sterile attitude towards all aspects of his crimes startled many members of the enquiry team. This prompted Superintendent John Bennett to seek the assistance of a criminal psychologist for an expert opinion on Fred's state of mind. After analysing Fred's behaviour throughout the extensive 1994 interviews, psychologist Paul Britton advised Superintendent Bennett that Fred's blasé manner indicated he had committed so many offences over such a long period that he was now indifferent to the acts of torture, mutilation and murder. Britton added that although an offender of this nature may come to offend less frequently, he would be unlikely to cease killing altogether.
  
  One theory which may explain the sudden lull in the frequency of their murders is the fact that by the mid-1970s, the Wests had begun a practice of befriending teenage girls from nearby care homes, many of whom they sexually abused, with others encouraged to engage in prostitution within their home. The Wests established acquaintances—including several of their lodgers—willing to partake in their shared fetishes, which may have satiated the couple to a degree.
  
  Caroline Owens, Anna Marie West, and several other survivors of sexual assaults at the Wests' hands each testified at Rose's trial that she had been by far the more calculating, aggressive and controlling of the two. Owens stated that, at one stage in her ordeal, Fred said that they had abducted Owens primarily for Rose's gratification. It is possible Rose's increasing family size, plus the fact she and her husband had, by the mid-1970s, begun seeking avenues to exploit girls from care homes in addition to acquiring contacts—willing or unwilling—to submit to their fetishes, may have led Fred and Rose to decide that these avenues of control and domination were sufficient for their satisfaction.
  
  Four young women similar in age and physical characteristics to those Fred was later charged with murdering in Gloucestershire are known to have disappeared during the time Fred lived in Glasgow—one of whom, Margaret McAvoy, Fred had been acquainted with via his employment as an ice cream van driver. He had also rented a garden allotment adjacent to his house and which he frequently visited, although only a small section of this plot was ever cultivated. To one neighbour, Fred remarked that he used the remainder for "something special", about which he refused to elaborate. Much of the supposed cultivation of this allotment occurred in the early hours of the morning. Police were unable to investigate whether any further bodies were buried at this location, as these allotments were built over in the 1970s as a section of the M8 motorway.
