After 27 years of incarceration, Bobby Bostic walked out of prison in 2022. Bostic was sentenced to 241 years for a robbery he committed in 1995 at just 16 years old. In the year after gaining his freedom, Bostic continued writing — a passion introduced to him while in prison — and now teaches youth in St. Louis’ juvenile detention centers. In this encore of “St. Louis of the Air,” we revisit host Elaine Cha’s conversation with Bostic from 2023 about life since his release and the experience of teaching young people in the same detention centers he spent his teenage years.
