A person familiar with the investigation identified the second woman as Jill Kelley, a long-time friend of the Petraeus family and a Tampa, Florida volunteer social liaison with military families at MacDill Air Force Base.
Kelley went to the FBI after receiving threatening emails that eventually were traced to Broadwell, law enforcement and security officials have said, prompting an investigation that turned up evidence that Petraeus and Broadwell were having an extramarital affair.
“We and our family have been friends with General Petraeus and his family for over five years. We respect his and his family’s privacy and want the same for us and our children,” Kelley said in a statement obtained by ABC News.
Broadwell has not been available for comment and both the FBI and CIA have declined public comment on the matter.
The affair has raised questions about whether US national security was ever at risk and the timing of law enforcement and intelligence officials’ revelation of the matter to the White House, as well as who knew about the investigation before last week’s presidential election.
A person familiar with the investigation said Kelley initially approached a Florida field office of FBI — not FBI headquarters — with a complaint of cyber-harrassment. She had received numerous intimidating emails from a handful of different, opaque pseudonymous addresses.
Upon tracing them, the FBI found out that Paula Broadwell was behind them, this source said. They also found correspondence between Broadwell and Petraeus leading to the revelation of an affair between them.
In the emails sent to Kelley, Broadwell said things like “I know what you’re doing”, “back off” and “stay away from my guy”, the New York Post reported.
Meanwhile, Kelley asked for privacy on Sunday as she hosted a lavish birthday party for one of her children on the front lawn of her mansion-style home near MacDill Air Force Base in Tampa.
She declined to speak to news crews gathered outside.
More than 100 adults and children attended the party.
A source close to the Petraeus family confirmed that Kelley, and her husband, Scott Kelley, a Tampa cancer surgeon, became friends when Petraeus was stationed at MacDill from 2008 until 2010 .
The couples stayed in touch, later meeting in Washington when the Kelleys visited relatives.
MAILS STARTED IN MAY: WSJ
THE WALL STREET JOURNAL reported that the emails Jill Kelley found threatening and harassing began arriving in her inbox in May 2012. She didn’t know who sent them.
THE FBI used the emails’ metadata footprints to determine the locations they were sent from. They matched the places and established the sender was Paula Broadwell.
THE AGENTS thought they were after potential cybercrime or a leak of classified information, but instead found sexually explicit emails between two lovers.
BY LATE SUMMER, prosecutors and agents alerted senior officials at FBI and the Justice Department, including Attorney General Eric J Holder. In September, Broadwell admitted to the affair.
