Federal inquiry also open in UNC slaying

Federal prosecutors have opened their own investigation into the killing of former University of North Carolina at Chapel Hill student body president Eve Carson, according to a letter made public Thursday.

U.S. Attorney Anna Mills Wagoner mentioned that a federal investigation was opened March 14 – less than two weeks after Carson was found dead – in a letter sent to Orange County District Attorney Jim Woodall, who is handling the case.

Assistant U.S. Attorney Lynne Klauer said Thursday that Wagoner would not comment on the letter, saying the document reveals the only details being made public at this time.

Messages left at Woodall's office Thursday afternoon weren't immediately returned.

Demario James Atwater, 22, and Laurence Alvin Lovette Jr., 17, have been charged with first-degree murder and first-degree kidnapping in Carson's death.
