Sean Andrew Duncan, 22, of Sterling, Virginia, was sentenced on Friday to 20 years in prison, to be followed by a lifetime of supervised release, for obstructing a counterterrorism investigation and receipt of child pornography.
Assistant Attorney General for National Security John C. Demers, U.S. Attorney G. Zachary Terwilliger for the Eastern District of Virginia, and Assistant Director in Charge Nancy McNamara of the FBI’s Washington Field Office, made the announcement after sentencing by U.S. District Judge Leonie M. Brinkema.
According to court documents, Duncan altered, destroyed, mutilated, concealed and covered up a thumb drive and memory chip with the intent to impede and obstruct an FBI terrorism investigation.
He knowingly and unlawfully received images of minors engaged in sexually explicit conduct, and possessed thousands of such images including images of infants being sexually abused.
In the statement of facts, Duncan admitted to his involvement with ISIS and production of child pornography.
Obstruction of Justice
In June 2017, the FBI learned that Duncan had been in contact with an individual who had been detained in a foreign country for actively planning to travel to join ISIS.
In or around February 2015, Duncan told the individual that he wanted to make “hijrah” to Syria and that he wanted her to go with him.
Later in February 2016, Duncan was denied entry into Turkey and returned to the United States.
Around this same time, the individual told Duncan she was upset at work due to non-Muslim women wearing shorts that exposed their bodies.
Duncan replied with a link to a website, and a message saying she could “try this.”
The link contained pictures and instructions on how to make weapons and bombs.
The link was to an article titled, “How to build a bomb in the kitchen of your Mom” from Inspire magazine.
In December 2016, Duncan contacted the individual and told her that he had come back from Turkey, where he and his wife were deported back to the United States.
Duncan said he thought the FBI was monitoring him.
