Ex-CEO of death row records, Suge Knight says he knows who killed rapper Tupac Shakur. He came forward this week to announce he had cracked the case. a signed affidavit written by Knight?s attorney Thaddeus Culpepper states, ?Knight has known for many years that Reggie Wright Jr., the former Death Row Records security chief, and his ex-wife Sharitha were behind the murder of Tupac and attempted murder of Knight.? The theory is Sharitha was attempting a Death Row Records coup. She knew what she?d inherit if Knight was taken out of the picture. Sharitha allegedly enlisted the help of Wright. Knight?s admission was reportedly inspired by a new documentary, Tupac Assassination: Battle for Compton. The documentary claims that Suge Knight was the real target of the Las Vegas shooting.
