On Monday night, FBI agents spent hours taking documents and computers from the Dilworth house of the woman who allegedly had an affair with David Petraeus.
After watching FBI agents walk out with computers and boxes of documents, the key question is whether any of them contained classified information. If they did, experts say this could quickly go from a scandal to a criminal case.
With the eyes of reporters and neighbors centered on Paula Broadwell's house, neither she nor her family were anywhere to be found Tuesday. Blinds remained drawn and two cars in the open garage never moved.
While agents in Charlotte refused to say anything, sources told ABC News Tuesday that agents uncovered hundreds if not thousands of emails between Broadwell and Petraeus, many of them salacious in nature.
Charlotte defense attorney James Wyatt said the two could be in even bigger trouble if the emails went beyond their alleged romance.
“If this case involved national security matters then it’s a very serious situation, and if it doesn’t it's still obviously a situation that has national implications,” Wyatt said.
That's because the net cast by the federal investigation is now widening.
“On Sunday, the Federal Bureau of Investigation referred to the Department of Defense a matter involving Gen. John Allen,” said George Little, Department of Defense press secretary.
Allen is the top U.S. commander in Afghanistan, who succeeded Petraeus there. He's now being investigated for potentially inappropriate emails to Jill Kelley. She's the same Florida socialite Broadwell allegedly emailed, warning her to stay away from Petraeus.
As for the investigation into Broadwell, Wyatt said it's likely still centered in Washington, despite the obvious ties to Charlotte.
“Just because the search occurred here doesn’t mean charges would be brought here,” Wyatt said.
