The lawsuit states that Pérez, Nino Durden, their partner former officer David Mack, and "certain unknown persons" were responsible for the death of Christopher Wallace. The rapper was shot to death on March 9, 1997, as he and Sean Combs left the 11th Annual Soul Train Music Awards after-party held at the Petersen Automotive Museum on Wilshire Boulevard in Los Angeles. The lawsuit states the killing was committed "in a very efficient, organized and professional manner, suggesting that a high degree of coordination and planning preceded his murder." The suit further alleges that Pérez admitted to the LAPD that he and David Mack "conspired to murder, and participated in the murder of Christopher Wallace." It was alleged that Pérez was on duty during the night of March 9, 1997 but there was no evidence of that allegation.
