U.S. prosecutors say 47-year-old Colleen LaRose had agreed to kill a Swedish cartoonist who had offended Muslims. They say the suburban Philadelphia woman helped foreign terror suspects intent on starting a holy war in Europe and South Asia.
LaRose has been in custody since October 2009 and faced a possible life sentence under charges in the March 2010 indictment.
She and co-defendant Jamie Paulin-Ramirez of Leadville, Colo., are the rare U.S. women charged with terrorism. Paulin-Ramirez has pleaded not guilty since she was arrested in Ireland with other terror suspects in March.
