This is a very sad story. :(

Just curious - where does it say that the murderer was mentally ill? I did a quick read up of news articles on Google News, as well as the linked to NYTimes article, and couldn't see any mention of this.

Stating he was mentally ill when there is no evidence for this seems to me to be quite problematic as it leads people to think that this horrendous crime is almost an unfortunate accident. Sadly there are so many of these violent crimes against women all over the world by (mostly) men who aren't mentally ill at all, just vicious. You hear of more and more such stories every day and it's quite depressing. One might almost say there's a pattern, given the many examples...
