The FBI first arrested Amer Sinan Alhaggagi in November 2016 based on a sealed complaint alleging he had committed aggravated identity theft. FBI surveillance observed Alhaggagi collecting a UPS package from Trunk Club — an online men’s clothing store — addressed to a fictitious name. The clothing was paid for using a debit card in another person’s name. In all, Alhaggagi used the card to buy $4,932 in clothing from Trunk Club. In July 2017, a grand jury indicted Alhaggagi for three counts of identity theft as well as material support for ISIS. Alhaggagi allegedly opened and operated social media accounts to benefit the terrorist organization.
