Take a look in the kitchen

You slowly open the kitchen doors. The first thing you see is blood, blood everywhere on the back wall. The backdoor is still moving, as if someone just left. You and your friend slowly walk further on where you expect the body to be. ,,A shot right in the head." ,says your friend, ,,Lets see where the bullet landed." Are you some sort of a detectiv or did I miss someting?" ,reply you. ,,No I just love to watch crime series. And thats what they always do first, if you find the bullet you find the weapon and if you find the weapon, you find the killer!'', ,, or the killer finds you!", says the receptionist with a gun in his hand. You quickly throw yourself on the floor, you grab a knife and crawl towards the killer. But he sees you and starts shooting at you, but fortunately he misses. You hear your friend crying, bullets flying trough the air. You grab all your courage and run towards the killer and stab the knife into he his chest. You pull it back out and stab him again and again and again. He starts spitting blood and topples down.

A few houres later the hotel is full with police officers. They find 23 dead bodies and one family wich the recepetionist trapped in the top floor.
