A fantasist, Walker was able to pretend to be anything or anyone at any time, but the evidence against him was strong. A global positioning system later pinpointed Walker’s yacht to the area at the time when Ronald died. One of Ronald’s fingerprints was also found on a plastic bag on the boat and Sheena testified against her father, excusing her behaviour by claiming she had been hypnotised by him.
Walker admitted during his murder trial that he stole from clients in Canada, but has never confessed to killing Ronald. At Exeter Crown Court in June 1998, the jury took just two hours to convict Walker of Ronald’s murder and embezzlement. Mr. Justice Butterfield said Walker had committed “a callous, premeditated killing”.
