Suge Knight will not testify against the man arrested last week for involvement in the murder of rapper Tupac Shakur. According to the record executive, Duane 'Keefe D' Davis is not the killer.
Knight was in the car with Shakur 27 years ago when fire opened from another car. The 25-year-old rapper was killed.

The founder of Death Row Records, where Shakur was under contract at the time, says in conversation with TMZ that he does not want to testify against Davis. He also doesn't want to betray anyone.

Knight is himself serving a 28-year sentence for deliberately running over two men. One of the victims was killed. Knight and Davis are the only living people involved in the 1996 shooting.

Davis was arrested on Friday. He is said to have been in the white Cadillac from which Shakur was shot with three men.

Last summer, police searched a home linked to Davis. Magazine articles about Shakur and his death were found in the home. Prosecutors say Davis is the one who ordered Shakur's murder. It is unclear who actually fired.
