Execution on Anglesey

·1 hr 17 min·5 clips

A retired lecturer was lured outside by a sabotaged satellite dish and shot with a crossbow.

The drive starts quietly. On April 17, Wall takes his Land Rover Discovery to Jerry and Marie's cottage on Anglesey, and the vehicle's built-in GPS and telematics show him pulling into the driveway around 11 p.m. and staying there for about 23 minutes without going to the house. Then he moves on. A short drive takes him to Porth Davark beach, a secluded cove nearby, where he parks for over an hour before heading home after midnight. The timeline reads that stop as reconnaissance, because the prosecution argued he was checking the area and working out where to wait or park. The route gets tighter from there. The narration keeps coming back to the fact that he was driving his own vehicle, with the black box recording movements that later made the route easy to trace. Good Friday brings the return. Leading into the early hours of April 19, Wall is back at Porth Davark by 11:10 p.m., and the telemetry records the boot opening at 11:11 p.m., likely to retrieve the crossbow and a set of bolts, before it closes again 39 seconds later. The car tells on him. Each detail becomes another piece of the case, from the driveway wait to the beach stop to the boot opening, and the story uses those markers to show how carefully the plan had been laid. Jerry's situation sits in the background. The episode notes that on the same night Jerry told Richard Win Lewis there was no money left, adding a bleak domestic note without drifting away from the evidence. Anglesey stays beautiful. That contrast matters, because the show keeps returning to the idea that an idyllic place can sit beside something violent and shocking. The hosts respond to the stupidity of using the Land Rover as a witness, to the brutality of the crime, and to the fact that the trail leads back to Wall. The ending stays sober, closing by holding Jerry's family, friends, and loved ones in mind.

As heard by us

A grim case made sharper by the vehicle data that quietly gives it away.

The episode reconstructs a crossbow killing through vehicle telemetry and GPS, using a Land Rover Discovery to place Wall at the cottage driveway, then at Porth Davark beach, and later back at the vehicle boot at 11:11 p.m.
