Over a three year period, he recorded at least 20 victims, mostly women, in northwest Washington D.C., by recording through windows, cracked blinds and metal gates into the bathrooms and bedrooms of basement level apartments.
In one instance he recorded a woman from her private backyard as she posed for her boyfriend on Facetime. On another occasion he recorded a different women as she lay naked in the bathtub reading a book.
All of the video recordings took place in the late evening under the cover of darkness, usually while he walked his dog. He went back and filmed some of the women multiple times. His victims were unaware at the time that he was making videos of them.
Rosen was arrested in February in Fairfax County, Virginia for soliciting a minor for sex. Virginia police notified the Metropolitan Police Department once geolocation revealed that videos found on his phone were taken in Washington, D.C. He is still facing charges in the Fairfax case.
Rosen’s wife sat in the courtroom as all 11 counts were read aloud. Rosen stood and listened as the prosecuting attorney read through the salacious details of his actions. He and his wife walked side-by-side out of D.C. Superior Court.
“He pled guilty and he wants to get a grip on his life," said his attorney Bernard Grimm after the hearing.
Rosen was put on unpaid administrative leave from the State Department, according to Grimm.
Grimm said that his client's security clearance had been revoked and he was not expected to be allowed back to his job.
The State Department refused to comment, citing privacy concerns.
Rosen was released until sentencing under strict home confinement and electronic monitoring. He faces up to 11 years in prison and a possible fine of $11,000.
