DENVER (AP) – A civil liberties group has filed a records request with the Denver Department of Safety for video footage documenting the death of an inmate.

The American Civil Liberties Union of Colorado said Monday the videotape of 56-year-old Marvin Booker being shocked and subdued by sheriff’s deputies was never released, despite being cited as a reason no charges were filed in the street preacher’s death.

A phone call to the Department of Safety wasn’t immediately returned.

Booker died last year after he was placed in a “sleeper” hold and shocked with a stun gun. His family’s attorney said deputies piled on top of him. The family is suing the city and county.

Authorities say Booker refused to comply with deputies trying to subdue him, but are conducting an internal investigation.
