Case 086
The Empty Safe
A small office safe was found empty in the morning.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Drew
“Morgan is innocent.”
Kendall
“Hayden is guilty.”
Jordan
“Drew and Morgan are both innocent.”
Morgan
“Drew is innocent.”
Hayden
“Drew and Jordan are both innocent.”
Who is guilty?
Solution: Kendall
If Kendall is guilty, Kendall's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
