You find a bullet in your grandpa's head. Must be from a sniper you think. You go on to check your grandmother. You find the same type of bullet that was found in your granpa in her chest. From watching SVU you can tell that grandma had dies 2 minutes before your grandfather. Same person, same gun you mumble. Another elderly woman calls the cops thinking that you are cleaning up the scene. No one listens to you explain. You are dead.
