A family lawyer with no experience as a prosecutor says he'll mount a challenge to Durham District Attorney Mike Nifong. Steve Monks is chairman of the Durham County Republican Party. He says people are unhappy with the way Nifong has handled the case against three Duke lacrosse players who are accused of rape. Nifong defeated two challengers in the Democratic primary. No Republicans filed to run. Monks will have to get 6,500 signatures on a petition by the end of the month to qualify for the November ballot.
