you've been invited at one of you're friends' party,to your Surprise,there is a LOT of people,and a lot of food!

After some hours,you go to the bathroom,since you really need to go,and once you entered... A person,layed on the ground,their neck seemed to be cut... And they're... DEAD!!

you report this to your friend,which called the Police...

Someone really did this? What Monster would do this... Well,you'll need to figure out yourself! Goodluck!
