For the two-hour class, David Carrillo, the adjunct professor teaching for Adams State University, mostly kept his hands in his pockets as he lectured students in green uniforms, some bright and others faded with time.
Like his students at the Colorado Territorial Correctional Facility, Carrillo, 49, also wears green. He holds a position that is extremely rare in prison: He’s an incarcerated professor teaching in a prison bachelor’s degree program.
