The attorney for the man accused of orchestrating the murder of Tupac Shakur said his client was “ambushed” inside the jail. Duane “Keffe D” Davis, 61, was charged Sunday with battery by a prisoner for an incident inside the Clark County Detention Center.

Duane “Keffe D” Davis, the man charged with orchestrating the 1996 murder of rapper Tupac Shakur, faces an additional count of battery following a fight in the Las Vegas jail where he’s been held for more than a year

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.
