Case 034
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.
Kai
“Either Kendall or Logan is guilty.”
Kendall
“Either Frankie or Logan is guilty.”
Frankie
“Kendall is innocent.”
Sam
“Logan is guilty.”
Logan
“Frankie is guilty.”
Who is guilty?
Solution: Logan
If Logan is guilty, Logan's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
