Case 344
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.
Morgan
“Logan and Cameron are both innocent.”
Logan
“Morgan and Sam are both innocent.”
Sam
“Cameron is innocent.”
Blake
“Logan is guilty.”
Cameron
“Sam is innocent.”
Who is guilty?
Solution: Blake
If Blake is guilty, Blake's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
