Psychopathic Welsh burglar who was convicted in 2011 of the double shotgun murders of a couple on the Pembrokeshire coast in 1989 and another during a botched burglary nearby in 1985. Police believed he killed at least one other woman in 1989, and investigated the possibility he could also have been responsible for another double shotgun murder in Bridgend in 1993.
