Case 149
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.
Noah
“Elliot is guilty.”
Reese
“Either Dakota or Elliot is guilty.”
Dakota
“Neither Noah nor Sam is guilty.”
Sam
“Either Reese or Elliot is guilty.”
Elliot
“Either Reese or Sam is guilty.”
Who is guilty?
Solution: Elliot
If Elliot is guilty, Elliot's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
