PhilMick, I've just read the article again and it really was an awful tragedy. I didn't live that far from the scene of the accident and can't understand why I can't remember it happening. There are older members on here that may have a better recollection of it than me,
Looking through the articles again, Warwick was taking his girlfriend back to Conwy when it happened so presumably she lived there. In the Obituary notice there was a reference to a Mr &Mrs Jones (Conway) and Dilys, I just wonder if Dilys was the girlfriend.
In the report of the trial which we haven't seen yet, I would imagine his girlfriend, if she was well enough would appear as a witness and would therefore be named in the press. That's just a guess, no more than that.
