Mangum has requested Durham attorney Scott Holmes to represent her. While the judge granted her request, he said he cannot name Holmes as her court appointed attorney. That must be determined by Indigent Defense Services.
Mangum has had three court-appointed attorneys, all of whom she has requested be removed from her case.
Mangum posted bond in February and was released from jail.
She's charged with murder, assault with a deadly weapon and larceny in connection with the death of her boyfriend Reginald Daye.
Police say Mangum stabbed Daye during a fight in April 2011.
Daye died at Duke Medical Center several days later.
Mangum contends the stabbing was in self-defense. She and a group of her supporters also claim Daye's death was the result of a medical error and that there are troubling discrepancies in the medical examiner's report.
Mangum is best known for accusing a group of Duke University lacrosse players of sexually assaulting her while she worked as a stripper at a party in 2006. The accusations were later found to be false, and Attorney General Roy Cooper dismissed the charges.
