Orlando Anderson: Anderson was a member of the Southside Crips, a gang with which Tupac had a long-standing feud. He was identified by several witnesses as the person who shot Tupac from a white Cadillac on September 7, 1996. Anderson himself was killed in a gang-related shooting in Los Angeles on May 29, 1998.
Suge Knight: Knight was the CEO of Death Row Records, the label that Tupac was signed to at the time of his death. He was with Tupac in the car when the shooting occurred, and some have speculated that he may have been involved in the murder. However, there is no concrete evidence to support this claim.
The Notorious B.I.G.: Biggie Smalls, real name Christopher Wallace, was a famous rapper from Brooklyn who was frequently engaged in a contentious feud with Tupac. Wallace was shot and killed in Los Angeles six months after Tupac's death, and some have hypothesized that Tupac's death was a retaliation for Biggie's murder.
The LAPD: There are also some theories that suggest that the Los Angeles Police Department (LAPD) may have been involved in Tupac's murder. Some believe that the LAPD were targeting Tupac due to his gang affiliations and outspoken lyrics.
Despite these theories and suspects, no definitive conclusion has been reached regarding who killed Tupac Shakur. The case remains unsolved.
