Rafle

One of the players plays the witness (the game is played in several rounds, each will be witness in turn).
The witness chooses from his package an individual who will be the murderer and who has several characteristics (age, face, eyes, hair, etc.)
Each turn, a police player draws a card from a common package that will allow him to ask a question or pass his turn.
By deduction, the luckiest player will discover the murderer by elimination. After each question he will have eliminate options such as "the murderer has brown eyes" or "the murderer is 45 years old", when he's sure of who is the murderer he makes a suggestion, if it's right, he wins.
