Sometime last year, a young 8 month pregnant mother, who was living in a bedsit, drowned her three eldest children, all, I believe, under school age, before throwing herself from a multi story car park. I believe her to have had long term mental problems, because of which, unable to cope, her boyfriend had gone back to live with his mother. It has just been said in an interview that "No professional body could have predicted this would happen"!!! OK, maybe not, but surely the situation rang warning bells with SOMEONE.
