A 36-year-old-man thought he might get away clean if he swallowed a stolen diamond just before being caught by police. His clever ruse was foiled, however, and police waited several days for the situation to pass naturally.
Unfortunately, the would-be diamond thief’s digestive tract could not be motivated to pass the stone, so police obtained a warrant to obtain the stone – via colonoscopy, using a basket catheter inserted into the man’s rectum.
The story was obtained via a case study, so the subject was unnamed; needless to say, his story serves as a hard lesson to digest for any would-be thief. [Source]
