A very good point indeedHow old would CCTV guy be now? If he WAS the killer the police may have missed their chance at catching him, sadly. Assuming he is still alive he’d be what, around 70? And if he’s dead, the DNA they have won’t lead anywhere. I think this case WAS solvable but fear the passage of time has made it much much harder, if not impossible. I really hope I’m proven wrong one day, this case has bothered me since I first saw it on Crimewatch in the 90’s.
This case was absolutely solvable, but I get the impression that there was more going on here than we will ever know.
There are only really 3 or 4 viable persons of interest in the case, and if it was none of them, then it's anyone's guess.
