The former convict spends time talking with young people about the hardships of prison life. He talked with ninth-graders at the Thornridge School in Dolton during a recent assembly, making a presentation in a mockup of a 10-by-10 cell.

“I built this prison cell to give a visual to our young people that they know and understand that this is not what you are thinking,” he says.
