On a cold October night in 2016, an Audi crashed into a metal fence on a Walton street after a short police chase prompting two men inside to flee on foot.
However PC Helsby, one of the officers pursuing the car, had unwittingly stumbled on a far more sinister incident than a case of dangerous driving. As the constable and his colleague approached the stricken vehicle where it crashed, on Cairo Street, they realised someone was trapped in the boot.
Inside, the officers found 44-year-old drug-dealer Kenneth Murphy "in a terrible state". He had been struck with a crowbar and beaten to the point one eye was swollen shut, he was drenched in blood from a deep laceration to his forehead and was "absolutely petrified and pleading for help".
