Duane “Keefe D” Davis, a suspect in the 2Pac murder case, has been hit with an additional charge after getting into a physical altercation in jail.

Keefe D was involved in a violent brawl while awaiting trial for Tupac Shakur’s murder, leading to additional charges.

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.
