Paul Grabham was found guilty of Kirsty's murder in February 2010. During the trial the court heard that they had a 'stormy' marriage. Both worked as prostitutes and were often heard arguing by neighbours.
On 28th March 2009 they were on a night out in Swansea. They had taken cocaine and were drinking. Friends heard them rowing in the nightclub. Paul left and when Kirsty arrived home at about 4am the arguments started again. He then strangled his wife and kicked her.
Paul Grabham put Kirsty's body in a suitcase and drove along the M4. Near Bridgend he dropped the suitcase over a motorway bridge into undergrowth, hoping it would lie undiscovered. But a lorry driver found the body just a week later.
