A riddle

Can you figure this out while I am away? IM me the answers when you think you have it figured out: One bright day in the middle of the night, two dead boys began to fight. Back to Back they faced each other, pulled out knives and shot each other. A deaf policeman heard the noise and came and shot those 2 dead boys. If you do not believe my story is true, ask the blindman. He saw it too. Can you figure this out?
