Two 9/11 hijackers, Ahmed Alhaznawi and Ahmed Alnami, who are living in a Delray Beach, Florida, condominium, forcefully try to enter the apartment of a neighbor living below them. They say a towel has dropped from their balcony to hers and insist on entering to retrieve it. The apartment’s tenant, Maria Siscar-Simpson, is frightened and refuses to let them in. According to her account, a handyman shouts the men away, but they come back three more times. After Siscar-Simpson later tells her story to the FBI, agents will suggest the towel, which appears to have fallen on her roof, not her balcony, may have contained clothing with something important to the two future hijackers’ mission, perhaps a confirmation number for their 9/11 flights (Alnami’s flight was booked the previous day—see August 25-September 5, 2001). The bureau will later find evidence that the men lower themselves on guy wires to retrieve the towel this evening. [St. Petersburg Times, 9/1/2002]
