A Kansas City, Kan., man who told investigators he preferred jail to living with his wife pleaded guilty to bank robbery, U.S. Attorney Tom Beall said Monday.

Lawrence John Ripple, 70, pleaded guilty to one count of bank robbery in federal court.

On Sept. 2, 2016, Ripple robbed the Bank of Labor at 756 Minnesota Ave. in Kansas City, Kan., according to the criminal complaint. He then sat down in the lobby and waited for police. Ripple told investigators that after an argument with his wife he would rather go to prison than go back home.

A sentencing date hasn’t been set. He faces up to 20 years in federal prison and a fine up to $250,000, Beall said.
