A jewel thief claimed he couldn't have robbed the penthouse because he was bedridden with a broken leg and his heavy plaster cast went all the way up to his hip. Detective Vega checked the suspect's apartment, looked at his bathroom sink, and immediately charged him with the crime. What did Vega see?
Water stains inside the cast
If the cast went up to his hip and he was truly bedridden and washing normally, or if he walked around in the rain, the plaster would be ruined. Specifically, Vega saw that the inside of the plaster cast was lined with waterproof plastic or showed signs of being removed and put back on, proving the broken leg was a fake prop used to establish a false alibi.
