In April 2012, Dawn and George Kibble visited the flat of Dawn's sister Julie Davison, concerned for her wellbeing after repeated phone calls went unanswered. On arrival, they found Julie's lifeless body on the blood-stained floor of her kitchen. She'd been attacked, stabbed multiple times, and left for dead.

Julie's home had been burgled with the killer making off with her laptop, jewellery, cash, and items of her clothing. The Police immediately began to investigate the crime and found a cigarette butt close to the scene that became crucial in the case's progression.

The investigation saw Police zero in on a suspect, James Allen, who was captured on CCTV wearing Julie's coat and trainers. That afternoon he sold a necklace identical to one missing from Julie's home and was seen carrying a laptop computer in a bag identical to one missing from Julie's flat.

Three days earlier, he had killed 81-year-old Colin Dunford in Middlesbrough, again following a robbery at the victim's home.

A week on from the murder of Colin Dunford, Allen was arrested by an off-duty police officer in Leeds. In November 2012, Allen was found guilty of both murders and was given a life sentence with no parole for 37 years.
