Deaths of Griff and Patti Thomas 'do not add up'
"It was the first time I'd seen a dead body. I could smell a bit of burning, and I looked around the corner and I could see this body in a cushion of burned material - and there was Griff."
Nigel Rossiter was only a week into his new job as a postman when he discovered the bodies of Griff Thomas and his sister Patti Thomas 50 years ago.
The mysterious deaths sent a shock through the village of Llangolman, and police are now reviewing evidence to see whether they uncover the truth of what happened.
