Children are very rarely harmed by strangers, when they are harmed they are overwhelming harmed by people they known - parents, family, friends, neighbors, etc. When a young child is murdered, the killer is usually a parent or stepparent, not a stranger. Not only that but you are comparing apples (mortality) to pineapples (crimes in general).
