Khalid Almihdhar
Possible residence(s): Los Angeles, CA / New York, NY / San Diego, CA / Daytona Beach, FL
Visa status: B-1 Visa, B-2 Visa had expired.

There is a report that authorities have a surveillance videotape which shows Al-Midhar meeting in Malaysia with one of the suspects in the October 2000 bombing of the USS Cole. Al-Midhar lived in San Diego last year, may have lived in New York, and at some point moved east, joining Gold's Gym in Greenbelt, Md., just weeks before the attack. Al-Midhar had a B-1 visa - covering business travel and good for up to a year - and an expired B-2 visa, a travel visa which was good for one year. He is a known associate of Nawaf Al Hamzi, with whom he bought a car in 1998, a Toyota Corolla with California license plates. Both men took flying lessons at Sorbi's Flying Club in San Diego, asking to learn how to pilot Boeings, but were told they'd have to first master flying Cessnas and Pipers. A flying instructor says Al-Midhar had difficulty learning flying basics and at times would become afraid and start praying to Allah. In September 2000, Al-Midhar and Nawaf Al Hamzi rented a room for a few weeks from Abdussattar Shaikh, a retired English professor at San Diego State University and co-founder of San Diego's Islamic Center. Shaikh, who authorities say is not a suspect, called the FBI after the terror attacks. Agents confiscated his computer, which they believe was used by Nawaf Al Hamzi to communicate in Arabic in various chat rooms.

Majed Moqed
Possible residence: Caldwell, NJ

The FBI has not released any information on Moqed but it has been reported that he worked out at Gold's Gym in Greenbelt, Md., between Sept. 2 and Sept. 6, as did Khalid Al-Midhar, Nawaf Al Hamzi, Salem Al Hamzi and Hani Hanjour. A gym employee says despite his sales pitch for the men to join, two paid by the day, to work out with weights and machines, and three bought weeklong memberships, paying with "a wad of cash." Moqed, along with Hani Hanjour, is seen in a photo from a video surveillance camera, using an ATM machine on Sept. 5 in Laurel, Md.

Nawaf Alhazmi
Possible residence(s): Fort Lee, NJ / Wayne, NJ / Los Angeles, CA / San Diego, CA

An associate of Khalid Al-Midhar, with whom he bought a car - a Toyota Corolla - took flying lessons in San Diego, and shared a room, also in San Diego, from which authorities have seized a computer they believe he used for chat rooms on the Web. Al Hamzi got his San Diego landlord, who is not a suspect, to help him open an account at the Bank of America and also show him how to post a personal ad on the web, in English, seeking a Mexican wife. The ad got no responses. The instructor at the San Diego flight school says Al Hamzi and Al-Midhar were with two other men with first names that sounded like "Hani." While in San Diego, he is believed to have lived in Parkwood, an apartment complex in Clairemont, where the manager says he was a model tenant, prompt with the rent, who often stopped by for coffee and cookies. The FBI believes he may also have lived in Fort Lee, N.J., and Wayne, N.J. He was in the group that worked out at Gold's Gym in Greenbelt, Md., the week before the attacks and on Sept. 1, stayed at the Pin Del motel in Laurel, Md., signing the register with a New York address and driver's license.

Salem Alhazmi
Possible residence(s): Fort Lee, NJ / Wayne, NJ / San Antonio, TX / Jedda, Saudi Arabia

Salem Al Hamzi was one of the group that worked out at the gym in Maryland the week before the attacks.

Hani Hanjour
Possible residence(s): Phoenix, AZ / San Diego, CA / Hollywood, FL / Daytona Beach, FL
Believed to be a pilot.

Hanjour, who may have used several spellings of his name, is believed to have been the pilot who slammed the plane into the Pentagon. He is believed to have lived in Phoenix and San Diego, took English lessons in 1991 at the University of Arizona, and in 1996 might have lived in Oakland, Calif., and spent at least one month in Miramar, Fla., staying with a family who saw him as a "kind and gentle man" who liked children. A report says that a Hani Saleh Hanjoor was listed as living at the Valle Cita Garden Apartments in north Phoenix. The apartment complex manager says there's no record of any tenant by that name. FAA records show that a Hani Hanjoor received a commercial pilot's license in 1999, listing a post office box in Taife, Saudi Arabia, as his address. That Hanjoor took flight lessons at CRM Airline Training in Scottsdale, Ariz., in 1996 and 1997, leaving without taking all of the classes for which he had paid. Hanjoor might have been one of the two men seen by the San Diego flight instructor who taught Khalid Al-Midhar and Nawaf Al Hamzi. Hanjour was a member of the Sawyer School of Aviation's flight simulator club in Phoenix, which gives members unlimited use of a flight simulator, for $200 a month. The FAA Airmen Directory lists a Jani Saleh Hanjoor as having had a student pilot license, with an address corresponding to the CRM flight school. In the six weeks before the attack, Hanjour took flying lessons at Freeway Airport in Bowie, Md., where instructors thought his skills were so poor they refused to rent him a plane. He was part of the group that worked out at the gym in Greenbelt, Md.
