Sad Waste of Life

So the 13 year old girl that killed her family in Madicine Hat was just found guilty of 3 counts of first degree murder. That just freaks me out...what went so terribly wrong in her life that she would do such a horrible crime at such a young age (she was actually 12 at the time of the murders). What sort of sentence will she receive? Her whole life is essentially over. Geez...I have a niece and nephew that age. I can't imagine them having such issues that would cause them to act out in such a manner. Sad, so sad.
