I would also like to make a point regarding the Facebook searches, and just ask people to remember that there's other reasons for these searches rather than just 1: Serial killer, 2: Obsessed/struggling to cope worker.
This sounds like an incredibly tough job to do, and I can't imagine being responsible for a baby that dies and then moving on to looking after a different baby the next day. It must be hard.
It's understandable to me that someone might make them searches as a way of coping with grief, and may not be done for entirely unhealthy/stalker/malevolent reasons.
Now that's not to say that makes this person not guilty, but just an important point to make I think.
