Ali Saleh Kahlah al-Marri, from Qatar but a legal US resident, arrives in the US with his wife and five children, reportedly to pursue a master’s degree in computer science at Bradley University in Peoria, Illinois. [Peoria Journal Star, 12/19/2001; New York Times, 6/21/2004] Al-Marri appears to have been sent to the US by 9/11 mastermind Khalid Shaikh Mohammed (KSM). During his interrogation, KSM will identify al-Marri as “the point of contact for al-Qaeda operatives arriving in the US for September 11 follow-on operations.” He will describe al-Marri as “the perfect sleeper agent because he has studied in the United States, had no criminal record, and had a family with whom he could travel.” [Newsweek, 6/15/2003] However, there are doubts about the reliability of KSM’s interrogation, which is believed that have been obtained through the use of torture (see June 16, 2004). Al-Marri also lived in Illinois for part of 2000 under a different name. [New York Daily News, 1/11/2003] He is apparently related to Mohamed al-Khatani, who attempted to enter the US in August 2001 to join the 9/11 plot (see July 2002). [New York Times, 6/21/2004] In December 2001, al-Marri will be detained as a material witness to the 9/11 attacks (see December 12, 2001).
