Search warrants obtained by News4 are revealing new details about the case against a State Department official charged with soliciting a minor.
The warrants describe a series of conversations that police claim is between Daniel Rosen, a State Department counter-terrorism official, and an undercover Fairfax County police officer. The two chatted online and via apps on Rosen's smartphone, the warrants claim.
The chats started on Nov. 2, 2014, when the undercover officer posed as a 14-year-old in an ad on a website, according to the warrants. "No school!!!!" read the ad. "Mon and Tues are teacher workdays!!! My parents will be at work, come entertain me. ... Ask my real age if interested."
The officer then got a response that read "I'd love to, if you like older guys" and had a picture attached, the warrants said. The officer wrote back: "I'm 14. Interested?"
The chats later move into an unspecified messaging app, "a popular social networking app that is typically used by teens to communicate," according to the warrants.
The warrants go on to claim that the iPhone 6 used in those chats was found in Rosen's front left pocket.

The conversations spanned several months and varied between "communications that were casual and sexual in nature," the warrants said. Eventually the texts turned into discussions about meeting for sex, the warrants claim, but "Mr. Rosen was very hesitant to meet until he had proof he was texting with a real live fourteen year old."
The officer attempted to provide Rosen with proof, the warrants said -- and after one attempt he responded "Good. Now let's get naked lol."
Rosen was arrested on Feb. 24 and charged with one count of "use of a communications device to solicit a juvenile.'' He is out on bond while awaiting trial.
At his bond hearing, Rosen surrendered his passports and was ordered to have no contact with minors. He was also ordered to stay off the computer.
"We're pleased the judge under a presumption of innocence and gave him the benefit of the doubt," said his attorney, Chris Leibig. "He deserves it. "
