A dead 11 y.o. young boy outside a school and a now 95% paralyzed 7 y.o. girl are two examples off the top of my head which happened in Greece within the last five years. The bullets fell on the upper part of their heads. In the latter case, the mother said she heard a sound similar to piercing an egg's shell. In the latter case the murderer was actually found.
