 Defense attorney John Richilano argued the federal government only filed fraudulent sex-slave charges after failing to make a terrorism case against Al-Turki.They claimed Mr. Al-Turki was under FBI-investigation on possible terrorism links before his arrest.Federal court documents filed by the defense show that the Denver Joint Terrorism Task Force had Al-Turki under a "full fledge investigation" suspecting "he is closely aligned to terrorists and may be providing material support to terrorism."
