September 20, 2001 – FBI Director Robert Mueller admits that some of the alleged 19 hijackers identities are in doubt as at least seven of them appear to be alive.

"FBI Director Robert Mueller acknowledged Thursday that investigators may not know the true identities of some of the 19 suspected airplane hijackers from last week’s suicide attacks.

But while in Pennsylvania on Thursday for a tour of the crash site there, he raised fresh doubts about the accuracy of the identifications.

"We have several hijackers whose identities were those of the names on the manifests," Mueller said. "We have several others that are still in question. The investigation is ongoing, and I am not certain as to several of the others."

Officials refused to say how many hijackers may have used false identities, but officials of the Saudi Arabian government said Thursday that six of the men that the United States has named as hijackers killed in the attacks appear to be living in the Middle East.

The six Saudis are: Abdulaziz Alomari [Flight 11], Salem Alhamzi [Flight 77], Saeed Alghamdi [Flight 93], Ahmed Alnami [Flight 93], Wail Alshehri [Flight 11], and Waleed M. Alshehri [Flight 11]." – LA Times (09/21/01)
