A Virginia man was arrested for allegedly destroying evidence that linked him to ISIS.
Sean Andrew Duncan, a convert to Islam, was also suspected of planning a terror attack and providing information to an ISIS contact about building homemade bombs.
Duncan and his wife tried to travel to Turkey in 2016 but were denied entry and returned to the U.S. At that point, he was interviewed by the FBI. Two days later, he deleted his Facebook account and changed his phone number.
Duncan was named as a U.S. contact by an ISIS supporter in custody overseas. The FBI also said Duncan gave advice on vetting questions to an undercover FBI agent posing as an ISIS recruit.
When agents showed up at his house in Sterling with a search warrant, he is said to have run out the back door, throwing out a bag with broken pieces of a thumb drive soaked in an unidentified liquid.
A relative reported that after he converted to Islam, he suspected Duncan had become radicalized.
