September 12, 2001-2002: FBI Intimidates Witnesses Who Saw Atta in Venice; Tells Them to Keep Quiet

A number of witnesses who claim they saw Mohamed Atta living in Venice, Florida in early 2001 later allege that, in the aftermath of the 9/11 attacks, they are intimidated by the FBI and told to keep quiet about what they knew. Amanda Keller, who claims to have lived with Atta during early 2001 (see (February-April 2001)), later says that, even after she moved away from Venice, FBI agents called her every other day for several months after the attacks. She tells investigative reporter Daniel Hopsicker about “intimidation by the FBI” that she suffered, adding, “They told me not to talk to anybody, to keep my mouth shut.” Stephanie Frederickson, who remembers Keller and Atta living next door to her in the Sandpiper Apartments in Venice, later recalls, “At first, right after the attack, [the FBI] told me I must have been mistaken in my identification. Or they would insinuate that I was lying. Finally they stopped trying to get me to change my story, and just stopped by once a week to make sure I hadn’t been talking to anyone. Who was I going to tell? Most everyone around here already knew.” Charles Grapentine, the manager of the Sandpiper Apartments, also confirms Atta having lived with Keller. He says that, after 9/11, the FBI “called me a liar, and told me to keep my mouth shut.” [Hopsicker, 2004, pp. 62-63, 65 and 88-89] According to the FBI’s account of events, Atta had left Venice by late December 2000 or early January 2001. Its account makes no mention of him returning there later. [US Congress, 9/26/2002] A former manager at Huffman Aviation, the Venice flight school attended by Atta in late 2000 (see July 6-December 19, 2000), also later alleges that the FBI intimidated him and told him to keep quiet. He says the FBI was “outside my house four hours after the attack.” He claims his phones were bugged after 9/11, and adds, “I thought these guys [Atta and his associates] were double agents. Why is that so incriminating?” [Hopsicker, 2004, pp. 149-150]
