A worthwhile story? How the hell is it 'worthwhile'? Will publicising it benefit the public? Will it prevent people from making very unforunate but very rare mistakes like this again? No.
Has it enriched my life? No. Do I need to know that this happened? No. Will it help the parents' grieving proccess? No. Will it bring their daughter back? No.
Will it make ordinary, sensitive people feel even worse about a mistake that they're probably already very, very sorry about feel even more wretched than they already do? Yes.
So no Martyn, it's not worthwhile at all. It's bordering on the malicious on the part of the parents and the press should know better than to have their strings pulled by a couple of bitter people who want other people to feel as bad as they do.
