I am highly irritated by the language of this article. The guy got killed, which was wrong, sure, but a 13 year old girl should not be described as a 21-year old's girlfriend. naked pictures of a 13 year old girl is CHILD PORNOGRAPHY! This was not a relationship, this was grooming a child. The Walthamstow Guardian article linked described him as her "lover", which was even worse!
If I was this girl's mum, I would have been tempted to do the same, but would have called the police instead.
