Several months into his second prison term, Dutton was sentenced to six days of solitary confinement, which allowed prisoners to take one book. By accident, he grabbed an anthology of black playwrights. He enjoyed the plays so much that, upon his release from confinement, he petitioned the warden to start a drama group for the Christmas talent show. The warden agreed on the condition that Dutton go back to school and get his GED. Dutton accomplished that and went on to eventually complete a two-year college program at Hagerstown Junior College (now Hagerstown Community College) in Hagerstown, Maryland, graduating with an Associate of Arts degree in 1976. Upon his release, he enrolled as a drama major at Towson State University (now known as Towson University) in the Baltimore suburb of Towson, Maryland, where he graduated with a Bachelor of Arts degree in 1978. After his time at Towson, Dutton earned a master's degree in acting from the Yale School of Drama in 1983.
