Judge accepts reduced plea for murderer diagnosed with schizophrenia High Court Judge Justice Iain Morley has accepted a plea of manslaughter by “reason of diminished responsibility” for Wilson Adams, after hearing psychiatric testimony from consultant psychiatrist Dr Griffin Benjamin. Adams was charged with murder in January 1997 after killing 61-year-old Gabrielle Stocker in cold blood while she relaxed on the sand at Runaway Beach. According to court documents, he bashed the woman’s head in with a rock and then slashed her throat because the voices in his head told him to do it. Adam’s attorney Wendel Robinson requested a reduced charge last year, when the consultant decided that the now 56-year-old-man was fit to plea, after spending more than two decades at the Clarevue Psychiatric Hospital.
