Since September 11, 2001 FBI investigation relieved revealed that al-Bayoumi has some ties to terrorist elements. Pasquale J. D'Amuro, the Executive Assistant Director for Counterterrorism and Counterintelligence testified in the October 9, 2002 hearing that
[w]e've been talking with the Government about collection on an individual named who has ties to al-Qa'ida, who has ties to Bayoumi.
In addition, the FBI reported the results of their search of al-Bayoumi's that, "after an exhaustive translations of Bayoumi's documents, it is clear that in Bayoumi's correspondence he is providing guidance to young Muslims and some of his writings can be interpreted as jihadist."
According to information acquired by the FBI after September 11, 2001, al-Bayoumi also noted on one of his school applications that he worked for a company called "Dallah/Avco." According to the FBI, Erean is a San Diego subcontractor of Dallah/Avco. According to a separate document, Dallah and Avco are under the same umbrella company, Avco Dallah Trans Arab, which is a subsidiary of Al Barakaat Investment and Development Company. Avco Dallah reportedly holds the contracts for cleaning and maintenance at the three major airports in Saudi Arabia. The document states that the company has links to Usama bin Ladin. FBI Headquarters was informed of the affiliation between Dallah/Avco and Al Barakaat in February 2001, but the San Diego Field Office apparently never got to this information.
According to FBI documents, al-Bayoumi's pay increase during the time that al-Hazmi and al-Mihdhar were in the United States. According to a recent analysis of ties between the terrorist attacks and elements of the Saudi Government, before al-Hazmi and al-Mihdhar arrived in the U.S., al-Bayoumi generally received approximately $465 per month in "allowances." According to the document, in March 2000, a month after al-Hazmi and al-Mihdhar arrived in San Diego, his "allowances" jumped to over $3700 a month and stayed constant until December 2000, when al-Hazmi left San Diego. Al-Bayoumi's allowances were then decreased to approximately $3,200 a month and stayed at that rate until al-Bayoumi left the United States in August 2001, approximately one month before the September 11th attacks.
