Case 245
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.
Cameron
“Either Riley or Lane is guilty.”
Riley
“Lane and Sam are both innocent.”
Lane
“Cameron is guilty.”
Sam
“Lane and Hayden are both innocent.”
Hayden
“Either Cameron or Riley is guilty.”
Who is guilty?
Solution: Cameron
If Cameron is guilty, Cameron's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
