Christopher Wallace's murder is believed to have been in retaliation for the murder of Tupac Shakur. Tupac Shakur was a member of Death Row Records, run by Marion "Suge" Knight. Knight is known to have hired off-duty Rampart cops for security such as Kevin Gaines, who was shot to death by fellow LAPD officer Frank Lyga on March 18, 1997. Knight, who grew up in Compton, is well known for his ties to the Bloods. Following his arrest, detectives found several photos of Rafael Pérez flashing Blood gang signs. The connection between Pérez and the murder of Christopher Wallace has long been a source of speculation by the LAPD.
