Broadwell Threatened Jill Kelley in Emails

The whole mess is getting ickier

The menacing emails sent by David Petraeus' ex-mistress to a Florida socialite promised to make the apparent rival "go away" and boasted of her friends in high places, the Daily News has learned.

The notes Paula Broadwell sent to Jill Kelley were far more sinister than previously reported and seemed like the rantings of someone "clearly unhinged," a close friend of Kelley told The News Monday.
