On November 6, 1997, fellow CRASH officer David Mack and two accomplices stole $722,000 during a robbery at a Bank of America branch near the University of Southern California campus. According to the Tupac documentary "Assassination: Battle for Compton", citing official legal documents, a reliable jail informant by the name of Ken Boagni, who befriended Rafael Pérez in prison, stated Pérez claimed the money stolen in the bank robbery was intended to go to Harry Billups, also known as Amir Muhammed, who was friends with Mack, for allegedly carrying out the murder of rapper Christopher Wallace, also known as Biggie Smalls. Billups had not been paid in full by his contractors, namely Reggie Wright Jr. and David Kenner, because he failed to also murder Sean Combs, the second intended target. Boagni claimed both Pérez and Mack were involved in the murder of Wallace, but Billups was the shooter.
