This year, on 1 October, Marion Rilka was brutally stabbed in the hallway of her home in Hove, East Sussex. Detectives have very little evidence and can find no motive for her murder, but a woman living nearby remembers a strange, menacing man she turned away from her door less than an hour before Marion was killed. Detective Chief Inspector Tim O'Connor from Sussex police, is in the studio with the latest news of the investigation.
