Marvin Booker, a homeless man who died at the hands of sheriff's deputies at the Denver jail, is the subject of a new documentary.

The film traces the life and death of Marvin Booker through recollections from his family and their efforts to uncover how Booker died. 

The case resulted in a $6 million award to the family -- the highest payout in an excessive force case in Denver's history.

The film, "Marvin Booker Was Murdered," premiers Thursday night at the Cleo Parker Robinson Theater in Denver.

Wade Gardner, who made the film, spoke with Colorado Matters host Andrea Dukakis.
