More than 100 sought in probe

Sun National Staff

WASHINGTON - Federal investigators said yesterday that they want to interview more than 100 people who could have ties to Tuesday's devastating attacks as they released a smaller, grimmer list - the names of the 19 suspected suicide hijackers who are presumed dead along with their thousands of victims.

One of them, Mohamed Atta, 33, a trained pilot from the United Arab Emirates, is believed to have met with co-conspirators in Prince George's County before the attack, according to federal investigators in Maryland. He is believed to have helped hijack one of two planes in Boston - American Airlines Flight 11 - and then piloted it south into one of the World Trade Center's twin towers.

Investigators would not say whether those at the meeting included the hijackers of American Airlines Flight 77, which departed from nearby Washington Dulles International Airport and crashed into the Pentagon.

The list included six other men who are believed to have been trained as pilots, among them Marwan Al-Shehhi, 23, who lived for a time with Atta in Hollywood, Fla., and in Hamburg, Germany, where both were engineering students. Al-Shehhi was on the second hijacked flight from Boston, United Flight 175, which also smashed into the World Trade Center.

Last night, a man identified as a material witness with information highly relevant to the investigation and considered a high-flight risk was arrested at John F. Kennedy International Airport in New York, said New York City Police Commissioner Bernard Kerik.

In other developments, rescue workers found early yesterday the flight data and voice recorders belonging to Flight 77 at the Pentagon. Searchers uncovered the crucial investigative tool a day after the flight data recorder was found in the western Pennsylvania wreckage. Last night, the voice recorder also was found.

All data recorders were turned over to National Transportation Safety Board investigators. The Pentagon voice recorder was damaged, hampering efforts to recover information from it.

As a group, the hijackers named yesterday were young; most were under 30. They all were believed to be of Middle Eastern descent, but they had most recently lived apparently ordinary lives with their families in places such as Delray Beach, Fla., and Fort Lee, N.J.

FBI Director Robert S. Mueller acknowledged yesterday that part of the great tragedy is knowing that the group capable of such terror was, at least for a time, so close at hand.

"The fact there were a number of individuals who were living here and attending flight school was a surprise," Mueller said. "Obviously, if we understood that to be the case, perhaps one could have averted it."

Investigators continued yesterday to follow thousands of leads that could help re-create the hijackers' final days and weeks and months.

Mueller said FBI agents across the country had served more than 30 search warrants and hundreds of subpoenas. Among items seized were computers and documents that could help trace the movements and plans of the group.

The FBI's activities caused a flurry of attention Thursday evening, when all New York airports were shut down as agents questioned about a dozen people, including the man who was charged last night. Early reports said agents had stopped passengers who had been caught carrying false identification, knives and certificates from a Florida flight school. The FBI denied those reports, saying the passengers were being held for suspected violation of immigration laws.

Early yesterday, investigators said all but one of the persons taken into custody had been released.

The man charged last night was detained after his name turned up on a list of 52 that was contained in a security directive sent by the Federal Aviation Administration to U.S. aircraft operators Thursday, according to officials.

Those named on the list, among them Atta and most of the suspected hijackers, were described as "individuals [who] may be associated with terrorist activities and may travel or attempt to travel by commercial aircraft."

None of those released from detention had connections with the terrorist attacks against the World Trade Center and the Pentagon, said Barry W. Mawn, the assistant FBI director who oversees the New York field office.

Agents working the huge investigation - dubbed "Penttbom" (for Pentagon, twin towers, bomb) - have prepared a list of more than 100 people who were wanted for questioning in connection with Tuesday's events. The list, which was different from the FAA list and has not been made public, was distributed to various federal agencies and about 18,000 police departments and was expected to be continuously revised.

Roughly half of the individuals named on the FAA list had home addresses in Vero Beach, Fla., about a two-hour drive north of Delray Beach, the home address listed for seven of the 19 suspected hijackers.

Several of the hijackers had not only lived in the same place, but they also shared a last name. Justice officials would not say yesterday whether the men were related.

Justice officials did not release countries of origins for any of the suspected hijackers. Several of the hijackers also have listed multiple birth dates and multiple recent residences. In addition to Atta and Al-Shehhi, other suspects were:

On American Airlines Flight 11:

Satam Al Suqami, 25, of the United Arab Emirates; Waleed M. Alshehri of Florida, no age available; Wail Alshehri, 28, of Hollywood, Fla., and Newton, Mass.; Abdulaziz Alomari of Hollywood, Fla., no age available.

On United Airlines Flight 175, which crashed into the south tower of the World Trade Center:

Fayez Ahmed, Ahmed Alghamdi, Hamza Alghamdi and Mohald Alshehri, all of Delray Beach, Fla., no ages available.

On American Airlines Flight 77, which crashed into the Pentagon:

Khalid Al-Midhar, of southern California and New York; Majed Moqed, no information available; Nawaq Alhamzi, of Fort Lee, N.J., and Wayne, N.J., and California, age not available; Salem Alhamzi, also of Fort Lee, N.J., and Wayne, N.J., and Hani Hanjour of Phoenix, Ariz., and San Diego, no ages available. Hanjouri was also listed on the document distributed to the airlines with an address in Fort Lee, N.J., which turned out to be nonexistent.

On United Airlines Flight 93, which crashed in Stony Creek Township, Pa.:

Saeed Alghamdi of Delray Beach, age not available; Ahmed Alhaznawi, 20, and Ahmed Alnami, age not available, both of Delray Beach; and Ziad Jarrahi, no information.

The FBI urged anyone who has any information about the hijackers to call 866-483-5137.
