Case 022
The Missing Painting
A framed artwork disappeared from a private hallway.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Dakota
“Either Peyton or Kai is guilty.”
Peyton
“Neither Kai nor Avery is guilty.”
Kai
“Avery and Riley are both innocent.”
Avery
“Riley is innocent.”
Riley
“Neither Peyton nor Avery is guilty.”
Who is guilty?
Solution: Dakota
If Dakota is guilty, Dakota's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
