DURHAM — Durham police have charged Crystal Gail Mangum, 31, with attempting to kill her boyfriend early this morning. Mangum is the woman who wrongly accused three Duke lacrosse players of rape in 2006. A judge this morning ordered that she remain in jail on a $1 million bond. Wearing a white jail jumpsuit, Mangum kept her head down during her court appearance today and said nothing as the charges from this morning’s incident were read.
