Charlotte, North Carolina - Federal agents are inside the home of the Charlotte author at the center of a scandal involving CIA Director David Petraeus, who resigned on Friday.
While agents on scene would not confirm what they were looking for, nearly a dozen agents were seen carrying boxes and taking photographs inside the home.
Paula Broadwell, the biographer who wrote a book about retired four-star general David Petraeus, 60, has not been seen at her Dilworth home since the news connecting her to an extramarital affair with Petraeus.
Broadwell spent a year with Petraeus in Afghanistan from July 2010 through July 2011 interviewing him for a book she co-wrote, "All In: The Education of General David Petraeus." This was during the period while he led the International Security Assistance Force there.
On Friday it was announced that Petraeus tendered his resignation to President Barack Obama, citing the affair.
An investigation started with harassing emails sent by Broadwell to another woman and eventually led the FBI to discover the affair, U.S. officials told The Associated Press on Saturday.
The official said the FBI investigation began several months ago with a complaint against Broadwell, a 40-year-old graduate of the U.S. Military Academy and an Army Reserve officer.
Some of Broadwell's neighbors describe the family as "likeable, outgoing, and ambitious."
One neighbor who didn't want to go on camera said the family is on "a planned vacation," but their home here in Dilworth is catching part of the glow of an intense national spotlight.
"People all over Dilworth, all over Charlotte, all over the country do things that none of us know about, and this is some that just became very public," neighbor Sarah Curme said.
A note from Fed Ex is attached to the door, the family's vehicles are parked in the driveway and those who are curious drive by with a simple question. Is that the house?
Former Charlotte Observer editor Ed Williams has worked with the woman at the center of the storm on a project to assist wounded veterans.
"She's our neighbor and they're a good young couple," he said. "I think if people knew her whole and as a full person, they'll understand that she did something that if she could take it back, I'm sure she would."
Liz Kearley showed up with her camera, but she expressed a concern for the younger residents who live inside the home, the Broadwell children.
"I don't think you can ever get used to it," she said. "And the bad thing to all this there are children involved, and also they're thrust into this kind of environment they don't need in."
The Broadwells have been in touch with their neighbors, but so far there is no word when the family will return home.
Meanwhile, information has emerged about a Florida woman who allegedly received harassing emails from Broadwell which led federal investigators to discover Petraeus' sexual indiscretion with Broadwell.

A senior U.S. military official identified the second woman as Jill Kelley, 37, who lives in Tampa, Fla., and serves as an unpaid social liaison to MacDill Air Force Base in Tampa, where the military's Central Command and Special Operations Command are located.
Staffers for Petraeus said Kelley and her husband were regular guests at events he held at Central Command headquarters.
In a statement Sunday, Kelley and her husband, Scott, said: "We and our family have been friends with Gen. Petraeus and his family for over five years. We respect his and his family's privacy and want the same for us and our three children."
According to a friend and former top aide, the affair began in 2011, two months after Petraeus took the reins as CIA director. It reportedly ended nearly 4 months ago.
Petraeus and his family are said to be devastated over the affair, especially his wife Holly, who "is not exactly pleased right now," said Steve Boylan, a friend and former Petraeus spokesman who spoke to Petraeus over the weekend.
"After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair," Petraeus said in the letter to the CIA workforce on Friday. "Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours."
Concerned that the emails he exchanged with Broadwell raised the possibility of a security breach, the FBI brought the matter up with Petraeus directly, according to the official, who spoke on condition of anonymity because he was not authorized to publicly discuss the investigation.
The FBI approached the CIA director, who earned acclaim for his leadership of the wars in Iraq and Afghanistan, because his emails in the matter were in most instances sent from a personal account, not his CIA one.
By Friday evening, multiple officials identified Broadwell, who spent the better part of a year reporting on Petraeus' time in Afghanistan.
Members of Congress said they want answers to questions about the affair that led to Petraeus' resignation.
"We received no advanced notice. It was like a lightning bolt," Democratic Sen. Dianne Feinstein of California, who heads the Senate Intelligence Committee, said.
House intelligence committee chairman Mike Rogers, R-Mich., and ranking member Dutch Ruppersberger, D-Md., will meet Wednesday with FBI deputy director Sean Joyce, and CIA acting director Michael Morell to ask questions, including how the investigation came about, according to a senior congressional staffer who spoke anonymously because he was not authorized to discuss the investigation publicly.
"He screwed up, he knows he screwed up, now he's got to try to get past this with his family and heal," said Boylan.
Since Petraeus' resignation, the book jumped from a ranking on Amazon of 76,792 on Friday to 145 by lunchtime on Monday. Broadwell's website was taken offline around 7:15 p.m. on Friday night.
Broadwell, who is married with two young sons, has not responded to multiple emails and phone messages. Broadwell planned to celebrate her 40th birthday party in Washington over the weekend, with many reporters invited.
But her husband emailed guests to cancel the event late Friday.
CIA officers long had expressed concern about Broadwell's unprecedented access to the director.
She frequently visited the spy agency's headquarters in Langley, Va., to meet Petraeus in his office, accompanied him on his punishing morning runs around the CIA grounds and often attended public functions as his guest, according to two former intelligence officials.
As a military intelligence officer in the Army Reserve, Broadwell had a high security clearance, which she mentioned at public events as one of the reasons she was well-suited to write Petraeus' story.
But her access was unsettling to members of the secretive and compartmentalized intelligence agency, where husbands and wives often work in different divisions, but share nothing with each other when they come home because they don't "need to know."
In one incident that caught the CIA staff by surprise, Broadwell posted a photograph on her Facebook page of Petraeus with actress Angelina Jolie, taken in his 7th floor office where only the official CIA photographer is permitted to take photos.
Petraeus had apparently given Broadwell the photo just hours after it was taken.
Petraeus' staff in Afghanistan similarly had been concerned about the time Broadwell spent with their boss on her multiple reporting visits to the war zone.
Following standard military procedure with senior officers, they almost always had another staffer present when she met with him at his headquarters, though they did have some meetings alone.
Military officers close to him insist the affair did not begin when he was in uniform.
Petraeus' resignation comes just before a crucial scheduled appearance before congressional intelligence committees next week to testify on what the CIA knew, and what it told the White House, before, during and after the attacks that killed the U.S. ambassador and three other Americans in Libya on Sept. 11.
Congressional officials say Morell will testify instead, as acting director of the CIA.
