The thief stashed the loot so he wouldn't be caught with it. A witness said he looked "high on drugs".
He was arrested later when he came back to retrieve the money. I guess it's true: the perp always returns to the scene of the crime.
He'll get a clean, dry bed, clean clothes, a shower, food, medical treatment if needed, a cellmate to talk story with, and a lawyer's services.
Not bad for a failed crime of opportunity.
