Midway through their 1989 summer tour of Pembrokeshire, two experienced walkers, Gwenda and Peter Dixon, were found shot dead on the coastal path from Portglais to St. Justinians. Witnesses remembered hearing shots at about 11 a.m. on Thursday, June 29th.
Robbery seems to have been the motive. Peter Dixons credit card was used four times to withdraw cash after he was murdered. A scruffy-looking motor-cyclist was seen on each of the four occasions. Another theory, less likely, is that the couple, from Oxfordshire, were killed because they had stumbled accidentally on an IRA cache.
