The murder case was indeed where the stone was dropped off a bridge onto the A463 near Blaenau. The occupant of the car was not a 'blackleg', as you so colourfully put it, but was a guy driving a car. I don't think his job, name or background were ever mentioned in the press or on TV. The charge was slackened because the kids who dropped the rock were just dropping a rock, and hadn't set out to kill anybody.
