Case 247
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.
Alex
“Either Parker or Finley is guilty.”
Parker
“Neither Drew nor Finley is guilty.”
Dakota
“Parker is innocent.”
Drew
“Dakota is innocent.”
Finley
“Alex is guilty.”
Who is guilty?
Solution: Alex
If Alex is guilty, Alex's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
