Timonthy Dunbar spent the last three months of his 41-year prison sentence in the PREP Center, where 232 men have graduated since 2022. The Parole Board sends men from the prison system to the center, and judges have also started sending men on probation there, said Cam Ward, the director of the Alabama Bureau of Pardons and Paroles. So far, none of the men who have graduated from the three-month program have committed a crime.
