Case 025
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.
Harper
“Logan is innocent.”
Dakota
“Neither Harper nor Lane is guilty.”
Lane
“Harper and Logan are both innocent.”
Taylor
“Either Lane or Logan is guilty.”
Logan
“Harper and Lane are both innocent.”
Who is guilty?
Solution: Taylor
If Taylor is guilty, Taylor's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
