The investigators were quickly able to link the 19 men to the terrorist organization al Qaeda, by accessing their intelligence agency files. The "New York Times" reported on September 12 that: "Authorities said they had also identified accomplices in several cities who had helped plan and execute Tuesday's attacks. Officials said they knew who these people were and important biographical details about many of them. They prepared biographies of each identified member of the hijack teams, and began tracing the recent movements of the men." FBI agents in Florida investigating the hijackers quickly "descended on flight schools, neighborhoods and restaurants in pursuit of leads." At one flight school, "students said investigators were there within hours of Tuesday's attacks." "The Washington Post" later reported that "In the hours after Tuesday's bombings, investigators searched their files on Al Suqami and [Ahmed Alghamdi, noted the pair's ties to al-Marabh and launched a hunt for him."
