The confession protects the crime
A suspect admits stealing a gallery painting at 9 p.m. If accepted, that time would place him forty minutes from a warehouse fire started at 9 p.m. He really stole the painting at 8, leaving time to reach the warehouse.
What we believe
The painting and the suspect's knowledge of its hiding place make the confession attractive to an investigator facing a deadline.
What changes
The suspect gives true details of the theft but moves it an hour later. The detective knows travel between the two sites takes at least forty minutes.
Plant this clue
The suspect describes the gallery clock in detail but cannot explain the noisy fire drill that emptied the gallery at 9. Checking the drill log separates proof of the theft from proof of its time.
Two ways to take it further
- Let a genuine accomplice accidentally correct the timeline.
- Give the detective a deadline that makes accepting the confession tempting.
