That a 9 year old - who can't yet even have any real concept of life and death - would take their own life is genuinely heartbreaking.

I would say though that there is clearly a longer story here... he did not kill himself after "four days" of bullying. That part of the story is utter nonsense and really underemphasises the prolonged mental anguish that leads to suicide. Also the phrasing of "she reassured him she still loved him" seems a little odd, to me. I wonder if his family really did react as well as is being reported, to be frank.
