I remember a few years ago I was watching the Bill and in it, a baby is screaming constantly so his brother who is about 3 or 4 picks him up and throws him which causes the baby to die. The brother done it to stop him from crying. In this day, what would actually happen if this situation occurred? What would happen to the brother when he killed a baby at such a young age? Would he face prison or juvie when he's older or would they let it go?
