U.S. won't file charges against woman in Petraeus case Tue Dec 18, 2012 12:50pm EST (Reuters) - Federal prosecutors said on Tuesday they would not file any charges in the cyberstalking investigation of Paula Broadwell, the biographer whose affair with former CIA chief David Petraeus led to his resignation. "After applying relevant case law to the particular facts of this case, the United States Attorney's Office for the Middle District of Florida has decided not to pursue a federal case regarding the alleged acts of "cyberstalking" involving Paula Broadwell," the U.S. Attorney's office in Tampa said in a statement. Anonymous emails that Broadwell sent to Jill Kelley, a Tampa, Florida socialite who knew Petraeus, prompted an FBI investigation that exposed Broadwell's affair with Petraeus, a retired U.S. Army general known for his success in the Iraq war.
