One thing stands between Dustin Shane Duty and decades in prison: a small group of law students working to exonerate him through the University of Miami School of Law’s Innocence Clinic.

Duty has already spent about four years behind bars following a jury conviction and 20-year sentence for armed robbery. But his advocates at UM’s pro bono law clinic and the Innocence Project of Florida say Duty is the one who’s been robbed — of years of his life — by a system that incarcerated an innocent man.
