The last episode of the ITV drama The Pembrokeshire Murders aired last night.

Based on the re-investigation of two unsolved murders in the county and the subsequent arrest of local man, John William Cooper, the series stars Pontypool-born Luke Evans and Keith Allen.

Here we take a look back through the Western Telegraph archives from the moment Cooper was charged, through a crown court trial that included evidence from beyond the grave to the relief of the families of his victims, Peter and Gwenda Dixon and Richard and Helen Thomas.
