It’s a cruel sociological experiment. Lock up a 13-year-old boy for a murder that he swore he didn’t commit. Release him as a 30-year-old man. Then, give him $25 million. New from WBEZ Chicago, Motive is a true crime podcast hosted by Pulitzer Prize-winning journalist Frank Main, with original reporting from the Chicago Sun-Times.

Brian Nelson, the former leader of the Simon City Royals, describes his 28 years in prison. Nelson, like T.J. Jimenez, joined the Royals at a young age. Then they were both charged with murder, and they both ended up in a maximum-security prison.
