Murderer is a teen party game that has been around for a really long time.
Cut how ever many strips of paper that are comming to your party. On on write an X, on another write Detective, and on all the rest write witness.
Put each piece of paper in the bowl, and have the girls draw a paper. Whoever has the Detective sheet leaves the room. Then the murderer turns off the lights and gives someone a hug. Whomever she hugs lays on the ground and the Murderer leaves the room.The detective will then come in and ask the "living" questions about who did it, and then the detective must guess!
