A FARM labourer who killed a Witney couple has had a bid to appeal against his convictions dismissed today.

John Cooper was given a whole life jail term with no hope of parole last year for two double murders and a string of robberies in Wales in the 1980s.

He shot Witney holidaymakers Peter and Gwenda Dixon, 51 and 52, as they walked along the Pembrokeshire Coastal Path in June, 1989.

Four years earlier he had shot farmer Richard Thomas, 58, and his sister Helen, 56, after they caught him breaking into their home in west Wales.

Modern forensics techniques saw him brought to justice in 2011.
