I am watching my daughter play and cant image someone doing anything like this.
I don't care who you are you do this to a child and pain, suffering, death is what you deserve. Parent, sibling, mom, dad, friend, relieve, stranger. No holds you need to suffer the worst pain possible.
Such things make us all wish for some kind of harsh judgement and justice, that's for sure. There is something particulary upsetting about harming the innocent.
