Case 008
The Broken Seal
A tamper seal on a storage crate was cut overnight.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Riley
“Neither Taylor nor Reese is guilty.”
Rowan
“Neither Riley nor Taylor is guilty.”
Taylor
“Reese is innocent.”
Kendall
“Either Riley or Taylor is guilty.”
Reese
“Taylor is 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.
