U.S. Anti-Doping Agency officials met Saturday morning in Raleigh, N.C., with C.J. Hunter, the ex-husband of Marion Jones, according to sources, in a move that signals the agency is still pursuing its investigation of Jones.

Two weeks ago, Hunter met with federal agents involved in the investigation surrounding the Bay Area Laboratory Co-Operative (BALCO) and agreed to cooperate with all relevant agencies, according to his attorneys.

It is unclear what information, if any, Hunter provided about Jones during the meeting. He might know whether Jones was aware of a $7,350 check he wrote from her account to Victor Conte, the BALCO owner, in 2000. He also might be able to explain a coded calendar with the initials "MJ" on it that appeared to detail a schedule of drug use.

USADA provided those documents to Jones when they met at the end of May, according to her attorneys.

USADA last week notified four athletes -- Tim Montgomery, the father of Jones's infant son; Chryste Gaines, Alvin Harrison and Michelle Collins -- that they faced lifetime bans from the sport for alleged drug violations related to the BALCO case.

Though Jones and her attorneys have requested USADA close the case against Jones and publicly exonerate her, the agency has taken no such action.

Hunter and Jones were married for three years. They separated early in 2001. Hunter, an elite shot-putter, tested positive for the steroid nandrolone several times before the 2000 Summer Games in Sydney, leading him to retire from the sport.
