Robert Trigg case: Parents speak of their 'mental torture'

An inquiry has found Sussex Police 'missed chances' to catch a man who killed two girlfriends five years apart. Robert Trigg was jailed last July for the murder of Susan Nicholson and manslaughter of Caroline Devlin. After spending six years and thousands of pounds to get the police to re-open their investigation, Susan's parents spoke of their "mental torture". Report by Chulanin.
