District Attorney Mike Nifong has requested that he have himself removed from prosecuting the Duke Lacrosse rape investigation, ABC News has learned.
A source close to the investigation said Nifong sent a letter to North Carolina Attorney General Roy Cooper asking his office to assume responsibility of the case. Calls to the Attorney General's office and Mike Nifong's office were not yet returned.
Three Duke Lacrosse players, Reade Seligmann, Collin Finnerty, and David Evans were indicted in 2006 on charges of rape, sexual assault, and kidnapping.
The rape charges were dropped in December after the accuser could not recall key details of the alleged attack.
