But this is a case where victim and alleged killer are close family so it's completely different than any random killing.
I realise that, but relationships within families can be so strange. Look at Mikaeel Kular, murdered by his mother who loved all her other children dearly; even she couldn't understand why she hated only one of her children:
The court heard that Adekoya, who had a history of depression and had attempted suicide in 2001, had made internet searches including "I find it hard to love my son", "I love all of my children except one", "Why am I so aggressive with my son" and "Get rid of bruises".

That's beyond heartbreaking. It's a far closer relationship than Becky and NM, Mikaeel was a tiny child that everyone who met him seemed to adore, a wonderful, bright, shining little boy who was murdered in circumstances that still can't be understood, which sounds very like Becky.
What I'm trying, clearly badly, to say is: one has to look at all the circumstances around what happened. Ignoring one aspect of it in case it might offend people could prevent us from learning from it and possibly preventing such a thing happening in future.
I'm sorry, I didn't mean to offend anyone and I clearly have. Having been victim of the same crime more than once I am interested in what makes certain people victims, and I'm not going to apologise for it even if it's terribly non-PC of me to wonder how I'm responsible.
