This potentially explosive evidence involves an alleged conversation between former LAPD officers Rafael Perez and Perez’s cellmate in the L.A. County jail.

The federal judge in the case writes that the inmate reported that Perez had told him about his and Mack’s involvement with Death Row Records and their activities at the Petersen Automotive Museum the night of Biggie Smalls’ murder.

Death Row Records was the label behind another rap superstar, Tupac Shakur, who was murdered in Las Vegas just months before Wallace’s death.

The original lead detective investigating Wallace’s murder says Mack and Perez had close ties to Death Row.

Months after Wallace was killed, officers Mack and Perez were convicted for unrelated crimes — Mack for bank robbery, Perez for stealing cocaine and other serious felonies.

According to a newly-revealed court record, Perez’s cellmate told investigators “Perez and Mack were involved in Death Row Records. Perez got involved in Death Row through Mack.” “They went to all their parties and stuff,” the inmate said. Investigators say Perez also told the inmate he was at the scene of the Wallace murder.
