Walter Unbehaun has spent nearly all of his adult life behind bars, so it’s not surprising that he faces sentencing Thursday for yet another crime, a bank robbery last year. His reason for robbing the bank is surprising, though: He was homesick for prison.

The 74-year-old high-school dropout and part-time bathtub repairman probably isn’t the first long-term convict to find he prefers being barked at by guards to life on the outside, which has its own demands. But living alone and feeling unhappy, Unbehaun decided to change his situation by committing a crime in order to get caught.
