This is news; it's inevitable someone will start a thread on the topic (in the news forum).
And it's a fairly resonant topic for Mumsnet, what with most of us being mothers.
I'm not in the UK, and this didn't make our news. I had to google just now to find out who this woman was, and who Daniel was. It made for pretty shocking reading.
I am going to be honest, and say I am not at all sorry she is dead. And I don't think there is anything wrong with starting this thread in news. It is news, like it or not.
