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.
