Who is David from the play, Exonerated?

David is an African American man of about forty. He is described as "A gentle, sad man." Born and raised in Florida, David is only eighteen when he is falsely convicted of murdering a policeman during a grocery store robbery. When he was a child, David had strongly developed religious feelings, and he wanted to channel the power of God to cure the illness of a woman who lived across the street. In prison, he lost his sense of possessing a relationship with God and is still trying to recover it. He believes that the Kingdom of Heaven lies within, even though people tend to seek it in outer things.

David is based on the real life David Keaton.
