Vonnie LaConca

A man, possibly Mohamed Atta, stays for a time at the apartment of a 21-year-old blonde-haired pizza restaurant manager named Amanda Keller. Keller lives in the Sandpiper Apartments in Venice, Florida, the same complex in which Atta reportedly shared a (presumably) separate apartment with Marwan Alshehhi and four others months earlier (see (Mid-July 2000 – Early January 2001)). Stephanie Frederickson, a resident at the Sandpiper Apartments, later remembers Keller and Atta. She claims Keller moved in next door to her. She goes on to say, “Then one day in the middle of March she brought home Atta.” Her recollection of Atta mirrors that of others. She will call him “a really nasty guy,” and say that he “had no patience, and seemed mad at the world.” Charles Grapentine, the manager of the Sandpiper Apartments, later recalls seeing Atta at the complex for about three weeks in April, and confirms that he was living with Keller. Keller’s mother, Susan Payne, also meets Atta and later says, “I didn’t like him; he just seemed strange.” As well as his stay at the Sandpiper Apartments, the man, possibly Atta, briefly rents a home in North Port. Its owners, Tony and Vonnie LaConca, know him only as “Mohamed.” They will be questioned in the days after 9/11 by the Florida Department of Law Enforcement (FDLE), and describe him as 25 years old, “very polite,” “very handsome,” and with “beautiful, unblemished skin.” From talking with “Mohamed” and Keller, the couple learns he is training for a commercial pilot’s license at Huffman Aviation, the Venice flight school attended by Atta in 2000 (see July 6-December 19, 2000). The Sarasota Herald-Tribune will claim that Keller’s companion is not Mohamed Atta, but another man of Middle Eastern descent who also took flying lessons in Venice. But authorities will refuse to reveal the full name of this “unidentified fifth man,” and investigators are reportedly unable to find him. [Charlotte Sun, 9/14/2001; Sarasota Herald-Tribune, 9/23/2001; Hopsicker, 2004, pp. 57, 60-65 and 76] According to official accounts, plus the testimony of Huffman Aviation’s owner Rudi Dekkers, Atta left the Venice flight school around the end of 2000, months before “Mohamed” stays in the apartment of Keller. [US Congress, 3/19/2002; US Congress, 9/26/2002; 9/11 Commission, 8/21/2004, pp. 17 ] Investigative reporter Daniel Hopsicker later locates and interviews Amanda Keller, and she claims that the Middle Eastern man who was briefly her boyfriend was indeed Mohamed Atta (see March 2004). However, in 2006 she will retract this claim and say she lied to Hopsicker. She will say, “It was my bad for lying. I really didn’t think about it until after I did it.” [Sarasota Herald-Tribune, 9/10/2006] Keller, Charles Grapentine, and Stephanie Frederickson will all later allege that the FBI intimidated them after 9/11, and told them to keep quiet about what they knew (see (September 12, 2001-2002)).
