Hijackers Mohamed Atta and Marwan Alshehhi report their passports missing; Ziad Jarrah reports his missing in February 2000. [South Florida Sun-Sentinel, 9/28/2001; Der Spiegel, 2002, pp. 257-58] Alshehhi receives a replacement passport on December 26, 1999. [London Times, 9/20/2001]
2000: German Intelligence Stops Monitoring Atta’s Apartment
German investigators are monitoring Said Bahaji, a member of the Hamburg al-Qaeda cell, for his ties to Mamoun Darkazanli. They had been monitoring a Marienstrasse address where Bahaji had been living. But Bahaji moved out after his 1999 wedding (see October 9, 1999) to live down the street with his new wife. A request to continue monitoring the Marienstrasse address is denied in 2000 for lack of evidence. Bahaji had lived at that address with Mohamed Atta, Marwan Alshehhi and other members of the Hamburg al-Qaeda cell. Although Bahaji, Atta, and Alshehhi all moved out by mid-2000, other associates like Ramzi bin al-Shibh, Zakariya Essabar, and Abdelghani Mzoudi moved in. Atta’s name stayed on the lease until early 2001. [New York Times, 6/20/2002; 9/11 Commission, 7/24/2004, pp. 495]
2000-2001: 9/11 Hijackers Atta and Alshehhi Attend Florida Mosque
The Congressional Joint Inquiry will later find that several of the hijackers, including Mohamed Atta and Marwan Alshehhi, attend mosques in the US and that at least one of the mosques is in Florida. [US Congress, 7/24/2003, pp. 169 
] The Florida mosque attended by Atta and Alshehhi is the Al Hijrah mosque run by Gulshair Shukrijumah in Miramar, Broward County, Florida. Mohamed Atta and several other hijackers live near the mosque (see April 11, 2001) and train at nearby Opa-Locka airport (see December 29-31, 2000). After 9/11, the FBI will visit the mosque and ask Shukrijumah and his wife if they recognize the hijackers and if their son, Adnan, knew Atta or had mentioned trips to Pakistan and Afghanistan. [Miami New Times, 4/3/2003; Los Angeles Times, 9/3/2006] Atta is seen with Adnan Shukrijumah, a suspected al-Qaeda operative, in 2001 (see May 2, 2001). His father previously served as an imam at the Al Farouq mosque in Brooklyn. In addition to working as a translator for Sheikh Abdul-Rahman, he also testified as a character witness at the WTC bombing trial for one of the defendants, Clement Rodney Hampton-El, who attended Al Farouq. [FrontPage Magazine, 10/27/2003; Los Angeles Times, 9/3/2006] Gulshair Shukrijumah is receiving money from the Saudi embassy in Washington at this time. [Newsweek, 4/7/2003] In 2009, an FBI informant will claim that he tried to get close to both Atta and Adnan Shukrijumah at the Al Hijrah mosque in early 2001, but the FBI had him work on easier cases instead, because both of them were secretive and wary (see Early 2001). [ABC News, 9/10/2009] The army’s Able Danger data mining program identifies Atta as a member of an al-Qaeda cell centered on Brooklyn. Exactly how it does this is never disclosed, although Atta’s apparent association with Gulshair and Adnan Shukrijumah is one possibile explanation (see January-February 2000).
January-February 2000: Secret Military Unit Identifies Al-Qaeda ‘Brooklyn’ Cell; Four 9/11 Hijackers Are Named, Including Mohamed Atta
A US Army intelligence program called Able Danger identifies five al-Qaeda terrorist cells; one of them has connections to Brooklyn, New York and will become informally known as the “Brooklyn” cell by the Able Danger team. This cell includes 9/11 hijacker leader Mohamed Atta, and three other 9/11 hijackers: Marwan Alshehhi, Khalid Almihdhar, and Nawaf Alhazmi. According to a former intelligence officer who claims he worked closely with Able Danger, the link to Brooklyn is not based upon any firm evidence, but computer analysis that established patterns in links between the four men. “[T]he software put them all together in Brooklyn.” [New York Times, 8/9/2005; Washington Times, 8/22/2005; Fox News, 8/23/2005; Government Security News, 9/2005] However, that does not necessarily imply them being physically present in Brooklyn. A lawyer later representing members of Able Danger states, “At no time did Able Danger identify Mohamed Atta as being physically present in the United States.” Furthermore, “No information obtained at the time would have led anyone to believe criminal activity had taken place or that any specific terrorist activities were being planned.” [CNN, 9/21/2005; US Congress, 9/21/2005] James D. Smith, a contractor working with the unit, discovers Mohamed Atta’s link to al-Qaeda. [WTOP Radio 103.5 (Washington), 9/1/2005] Smith has been using advanced computer software and analysing individuals who are going between mosques. He has made a link between Mohamed Atta and Sheikh Omar Abdul-Rahman, ringleader of the 1993 bombing of the World Trade Center. [Fox News, 8/28/2005; Government Security News, 9/2005] Atta is said to have some unspecified connection to the Al Farouq mosque in Brooklyn, a hotbed of anti-American sentiment once frequented by Abdul-Rahman, which also contained the notorious Al-Kifah Refugee Center. [Times Herald (Norristown), 9/22/2005] Smith obtained Atta’s name and photograph through a private researcher in California who was paid to gather the information from contacts in the Middle East. [New York Times, 8/22/2005] Lt. Col. Anthony Shaffer claims the photo is not the well-known menacing Florida driver’s license photo of Atta. “This is an older, more grainy photo we had of him. It was not the best picture in the world.” It is said to contain several names or aliases for Atta underneath it. [Jerry Doyle Show, 9/20/2005; Chicago Tribune, 9/28/2005] LIWA analysts supporting Able Danger make a chart, which Shaffer describes in a radio interview as, “A chart probably about a 2×3 which had essentially five clusters around the center point which was bin Laden and his leadership.” [Savage Nation, 9/16/2005] The 9/11 Commission later claims that Atta only enters the United States for the first time several months later, in June 2000 (see June 3, 2000). [9/11 Commission, 7/24/2004, pp. 224] However, investigations in the months after 9/11 find that Mohamed Atta and another of the hijackers rented rooms in Brooklyn around this time (see Spring 2000). Other newspaper accounts have the CIA monitoring Atta starting in January 2000, while he is living in Germany (see January-May 2000). Atta, Alshehhi, Almihdhar, Alhazmi and other hijackers have connections to associates of Sheikh Abdul-Rahman (see Early 2000-September 10, 2001).
2000-August 2001: Atta and Other Hijackers Seen at Charlotte County Airport, Florida
Mohamed Atta, along with others of the alleged 9/11 hijackers, is believed by some to have resided in Punta Gorda, Florida before July 2000 (see Before July 2000), prior to his attending flight school in Venice, about 30 miles north of there (see July 6-December 19, 2000). He is also witnessed in Punta Gorda around July-August 2001 (see Mid-July-Mid-August 2001), well after the time he leaves Venice. Additionally, Atta and some other hijackers are reportedly witnessed at the Charlotte County Airport in Punta Gorda. Cathy Mohr, the owner of a cafe there, later says, “The picture [of Atta] in the paper looked really familiar and people from the airport said, ‘Hey you know they were here.’” [NBC 2 (Fort Myers), 4/24/2002] After seeing photos of them after 9/11, Frank Cvelbar, whose Aero Precision flight school is based at the airport, believes he has seen four of the alleged hijackers “very occasionally” visiting the airport, shopping in his school’s pilot supplies shop, or hanging around the airport’s lobby. Cvelbar will say he is “very sure” about having seen Atta, and “pretty sure” about seeing Marwan Alshehhi, Saeed Alghamdi, and Ahmed Alnami. [Charlotte Sun, 10/3/2001] A salesperson at Eastern Avionics, a vendor at the airport, later recalls Marwan Alshehhi having bought a pilot’s headset from them. After the sale, he starts receiving e-mails, apparently sent by Mohamed Atta (see Before September 11, 2001). After 9/11, the Punta Gorda Police Department will confirm handing over half a dozen pieces of information to the FBI. [Charlotte Sun, 10/2/2001; NBC 2 (Fort Myers), 4/24/2002] Yet according to official accounts, Atta and Alshehhi were only in this area when attending flight school in Venice. [US Congress, 9/26/2002; 9/11 Commission, 7/24/2004, pp. 223-253] When asked to corroborate or refute reports of the hijackers having been in Charlotte County, FBI spokeswoman Sara Oates will only respond, “The FBI has information but the FBI cannot disclose the information because the investigation is pending.” [Charlotte Sun, 10/3/2001]
2000-September 11, 2001: 9/11 Hijackers Living in US Make Many Calls to Saudi Arabia, Syria, and Other Countries
While living in the US, the 9/11 hijackers make at least 206 international phone calls. In 2006, these calls will be mentioned in a German intelligence report based on telephone records obtained from the FBI. There are 66 calls to Syria, 32 calls to Saudi Arabia, and 29 calls to Germany. A majority of the call are made from a cell phone registered to hijacker Marwan Alshehhi. Additional details on who was called, who else made the calls, when the calls were made, what other countries were called, etc… have not been made public. The Chicago Tribune will later note that the calls to Germany are not surprising since Alshehhi and some others were living there, but “the hijackers’ connections to Saudi Arabia and Syria are far from fully explained.” [Chicago Tribune, 3/8/2006] It is unknown when these calls were discovered, but reports suggest at least some of the hijackers’ international calls were being monitored by US intelligence as they were made (see Summer 2001, September 10, 2001, and Early 2000-Summer 2001).
Early 2000-September 10, 2001: 9/11 Hijackers Have Several Links to Sheikh Omar Abdul-Rahman
The 9/11 hijackers have links to several people associated with “Blind Sheikh” Omar Abdul-Rahman, the spiritual head of the group that bombed the World Trade Center in 1993. Abdul-Rahman has been in prison since the mid-1990s. 
9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi attend a mosque in San Diego that is visited by an unnamed associate of Abdul-Rahman who is under investigation by the Los Angeles FBI (see June 1999-March 2000); The mosque is also attended by Osama Basnan, who threw a party for Abdul-Rahman in 1992 (see Spring 2000); 9/11 hijacker Mohamed Atta is seen with Adnan Shukrijumah, son of Abdul-Rahman’s former translator (see May 2, 2001) and Atta and hijacker Marwan Alshehhi may attend a mosque run by his father (see 2000-2001); Hijacker Mohand Alshehri is seen near the Minnesota clinic where Abdul-Rahman is being held (see August 2001); Some hijackers have the same mailing address as Abdul-Rahman and at least one of his associates (see Before September 11, 2001); Khalid Almihdhar and other hijackers obtain false ID cards from Mohamed el-Atriss, an associate of an unindicted co-conspirator at Abdul-Rahman’s trial (see (July-August 2001)); [Lance, 2006, pp. 373] In addition, people attending a Bronx mosque are warned to stay away from lower Manhattan on 9/11 (see Early September 2001).
In early 2000, the Able Danger data-mining program apparently identifies Atta, Alshehhi, Alhazmi, and Almihdhar as members of al-Qaeda through their associations with people linked to Abdul-Rahman (see January-February 2000).
January 15, 2000-August 2001: 9/11 Hijackers Bring Money into US
Several of the 9/11 hijackers bring money into the US in the form of cash and traveler’s checks. At least $69,000 is imported this way: Nawaf Alhazmi and Khalid Almihdhar bring in about $15,000 (see February 4, 2000); Marwan Alshehhi purchases $2,000 in traveler’s checks in New York on May 31, 2000, apparently using money withdrawn from his Dresdner bank account in Hamburg; [9/11 Commission, 8/21/2004, pp. 136 ] Ziad Jarrah opens a bank account with a $2,000 deposit shortly after arriving in the US (see June 28-July 7, 2000); Majed Moqed, Wail Alshehri, Ahmed Alhaznawi, Saeed Alghamdi, Hamza Alghamdi, and Ahmed Alnami bring in traveler’s checks worth $43,980 purchased in the United Arab Emirates (see April 11-June 28, 2001); [9/11 Commission, 8/21/2004, pp. 137 ] Khalid Almihdhar brings in traveler’s checks worth $4,900 purchased in Saudi Arabia. [9/11 Commission, 8/21/2004, pp. 137 ]
Spring 2000: 9/11 Hijackers Atta and Alshehhi Rent Rooms in Brooklyn and the Bronx
Mohamed Atta and another of the 9/11 hijackers (presumably Marwan Alshehhi) rent rooms in New York City, according to a federal investigator. These rooms are in the Bronx and Brooklyn. Following 9/11, Atta is traced back to Brooklyn by a parking ticket issued to a rental car he was driving. However, immigration records have Mohamed Atta entering the US for the first time on June 3, 2000 (see June 3, 2000). The Associated Press article on this subject does not specify if Atta first stayed in New York before or after that date. [Associated Press, 12/8/2001] According to a brief mention in the 9/11 Commission’s final report, in the month of June, “As [Atta and Marwan Alshehhi] looked at flight schools on the East Coast, [they] stayed in a series of short-term rentals in New York City.” [9/11 Commission, 7/24/2004, pp. 224; Washington Post, 8/13/2005] Earlier in 2000, a US Army intelligence program called Able Danger identified an al-Qaeda terrorist cell based in Brooklyn, of which Atta is a member (see January-February 2000). Also, a number of eyewitnesses later report seeing Atta in Maine and Florida before this official arrival date (see April 2000; Late April-Mid-May 2000).
March 2000: German Intelligence Places Two 9/11 Hijacker Associates on a German Watch List
German intelligence places two members of the al-Qaeda Hamburg cell, Mounir El Motassadeq and Said Bahaji, on a German watch list. The two men, associates of future 9/11 hijackers Mohamed Atta, Marwan Alshehhi, and Ziad Jarrah, had come to the Germans’ attention because of their association with al-Qaeda recruiter Mohammed Haydar Zammar, who they meet regularly. The watchlisting means that their arrivals and departures to and from Germany will be reported immediately. [Der Spiegel (Hamburg), 2/3/2003; US Congress, 7/24/2003 ] Hamburg cell member Mohammed Haydar Zammar is also placed on a watch list at some point before 9/11 (see Before September 11, 2001). El Motassadeq was first investigated by German authorities in 1998 (see August 29, 1998). Bahaji was the target of a surveillance investigation starting in 1998 as well (see (Late 1998)). Bahaji may have recently traveled to Afghanistan with some associates using a route monitored by European intelligence agencies (see Late November-Early December 1999).
El Motassadeq’s Travels Will Be Noticed Three Times – Because he is watchlisted, German intelligence will keep track when El Motassadeq goes to Denmark twice, and when he flies to Istanbul on his way to a training camp in Afghanistan (see May 22, 2000). [New York Times, 1/18/2003]
Importance of Watchlisting – Author Terry McDermott will later comment about the watchlisting of El Motassadeq: “In Germany, this was not a casual event. In order to be placed on such lists, intelligence agencies had to go to great lengths to demonstrate to the Bundestag, the German parliament, that the person under question was of potential danger to the state. Being placed on the list indicated that El Motassadeq had been under investigation for some time. In that he was an integral part of the group that included [Atta], [Ramzi bin al-Shibh], and Alshehhi, this at the least implies that they were being watched too.” [McDermott, 2005, pp. 73, 297]
