Case 070
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.
Reese
“Either Jordan or Alex is guilty.”
Jordan
“Reese is guilty.”
Kai
“Either Reese or Jordan is guilty.”
Kendall
“Reese and Kai are both innocent.”
Alex
“Neither Kai nor Kendall is guilty.”
Who is guilty?
Solution: Jordan
If Jordan is guilty, Jordan's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
