[Daryn Kagan, Cnn Anchor:] We want to bring you the latest now on the investigation. In fact, investigators have uncovered more links tying Osama bin Laden's al Qaeda organization to the attacks of September 11. And our Susan Candiotti is here, she's been tracking it, and she has the latest. Susan, hello.
[Susan Candiotti, Cnn Correspondent:] Hello, Daryn. At least four of the suspected hijackers received training at camps in Afghanistan, an intelligence source tell CNN's Justice Department correspondent Kelli Arena. That would establish ties to Osama bin Laden. Source say authorities now believe most of the hijackers have ties to the al Qaeda network. Meantime, an FBI build-up in Germany, as investigator work closely with their counterparts overseas. Sources say there is growing evidence Germany might have been a central meeting place for those masterminding the attack. And in Great Britain, prosecutors rearresting pilot Lofti Raissi. They say he may have trained some of the hijackers. His attorney denies any connection. In Raissi's apartment, missing pages from his flight log. The FBI hopes to extradite Raissi on a separate charge of lying to the Federal Aviation Administration to get a pilot license. Raissi at one time took flight training in Arizona with one of the 19 named hijackers, Hani Hanjour. And in Iowa, another break. The FBI find someone they have been looking for since last week, named Youssef Hmimssa. His photo found during the search of a Michigan apartment linked to another man held on immigration charges.
[Unidentified Female:] It is very significant. It is someone we have been looking for. We didn't know who it was, and we would like to have the opportunity, and we will, to talk with this person and find out exactly who he is, and his name appeared on a false passport. So, we just we have a lot of work ahead of us.
[Candiotti:] Sorting out false identities continues to be a major problem for investigators. The FBI admits they are not sure of the real names of some of those identified in FBI photos as the hijackers. In fact, source say, during that when the case is over, it's possible some of the hijackers' true identities may never be known.
[Kagan:] Well, let's talk about other pieces of the puzzle they are still trying to put together. The money trail, where are they still looking, and what kind of information will it help them tell the story?
[Candiotti:] Well, the trail, as you can imagine, is very involved indeed. The trail goes from Nevada and Florida, for example, all the way to the United Arab Emirates. In some cases, in many cases, the suspected hijackers, sources say, were using debit cards, not credit cards, to try to hide their transactions to pay for some of their expenses. And in fact, near the end, right before the attacks, sources say that the suspects, some of them, were mailing back their leftover money. In fact, in one case, from a Kinko's copying store in Florida, all the way to a so-called money master, a pay master, in the United Arab Emirates.
[Kagan:] It will be interesting to hear a lot more. Susan Candiotti, thank you very much.
