Security footage shows 61-year-old Duane “Keffe D” Davis coming to blows with a 53-year-old inmate, who’s also charged with murder.

The big thing working against Davis is that he went on record in several interviews confessing to being involved in Pac’s murder. In 2008, he allegedly confessed to the murder as a part of a “proffer agreement,” meaning that anything he told investigators at the time could not be used against him in court.
