Case 281
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.
Harper
“Rowan and Elliot are both innocent.”
Logan
“Either Harper or Elliot is guilty.”
Sam
“Elliot is innocent.”
Rowan
“Harper and Sam are both innocent.”
Elliot
“Rowan is innocent.”
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.
