Zacarias Moussaoui moves from Oklahoma to Minnesota, in order to attend flight school training there. Moussaoui drives there with Hussein al-Attas, a friend who will stay with him in Minnesota. Curiously, on August 11, someone breaks into the Norman, Oklahoma, apartment that remained unoccupied since Moussaoui moved out of it at the end of May 2001. A neighbor’s bicycle is used to break through the door of the vacant apartment and a bloodstain is left on the wall. A neighbor “[tells] reporters that furniture was overturned as if someone was looking for something.” [MSNBC, 12/11/2001; St. Paul Pioneer Press, 9/10/2002; US Congress, 10/17/2002]
