Case 181
The Cut Cable
A network cable was cut in a restricted room.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Kendall
“Neither Riley nor Cameron is guilty.”
Blake
“Riley is guilty.”
Riley
“Kendall and Cameron are both innocent.”
Hayden
“Kendall and Riley are both innocent.”
Cameron
“Neither Riley nor Hayden is guilty.”
Who is guilty?
Solution: Blake
If Blake is guilty, Blake's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
