your ticket to a better night s sleep richard buckland confessed to killing dawn ashworth, but insisted he had nothing to do with the murder of lynda mann three years earlier. police were convinced he was lying and set out to find the truth here at the university of lester, ironically less than ten miles away from where both teenagers were murdered. dr. alec jeffries, a gentleman net cyst, had within researching hereditary diseases when he accidentally discovered an
