An antique pocket watch was stolen from a locked safe. The thief left behind a single fingerprint on the inside glass of the display case. The owner of the house had no fingerprints on file, but was arrested anyway. Why?
The fingerprint was on the *inside* of the glass
The safe was locked and the watch was inside. For a fingerprint to be on the *inside* of the glass cover of the watch case, it had to be placed there when the watch was manufactured or disassembled by the owner, proving the 'theft' was staged.
