He never adjusted to life on the outside, and with serious medical issues and a short time to live he longed for what he considered home.

Walter Unbehaun, 73, spent most of his adult life behind bars, and was apparently so unhappy living as a free man that he stuck up the BMO Harris Bank at 7077 W. Dempster St. in north suburban Niles on Feb. 9 with the intention of being caught, according to the Chicago Sun-Times.

He told FBI agents he “wanted to go back to the only life he knew — prison life,” according to court papers filed this week by the U.S. Attorney’s office.

…they say Unbehaun’s willingness to stick up a bank, even though he walks with a cane and has had hip-replacement surgery, shows just how determined he is to stay behind bars, making him a public danger at an age when most criminals have settled down.
