On 6 September 1924, twenty-one-year-old John Dillinger joined his friend Edgar Singleton in robbing a local grocer, Frank Morgan, as he returned home carrying the week's takings. Dillinger struck Morgan with a cloth-wrapped iron bolt. Both men were arrested, but despite Dillinger having no prior record, he received the harsher sentence: between 10 and 20 years. Singleton, the experienced criminal who had planned the job, hired a lawyer and walked away with a lighter term.
Inside the Indiana State Reformatory, Dillinger kept his head down, worked as a seamster in the shirt factory, and carefully cultivated friendships with hardened criminals including Harry Pierpont, Homer Van Meter, and Charles Makley. These men would later form the core of the Dillinger gang. He later wrote to his father: 'if I had gotten off more leniently when I made my first mistake this would never have happened.'
