December 14-25, 1999: Private Investigators Discover Al-Qaeda Sleeper Cell in California

Counterterrorism “tsar” Richard Clarke, hearing about Ahmed Ressam’s arrest earlier in the day (see December 14, 1999), hires a team of private terrorism analysts to complete a report on militant Islamic cells in North America. The Investigative Project on Terrorism, led by Steven Emerson, finishes the report just prior to the end of the year, hoping to help stop any millennium plots. [New Yorker, 5/29/2006] Investigator Rita Katz discovers that a man named Khalil Deek who has just been arrested in Jordan for a role in a millennium plot is a US citizen (see December 11, 1999). Using only public records, she begins looking into Deek’s activities in the US. She believes that she discovers a sleeper cell consisting of: [Katz, 2003, pp. 161-162]
Khalil Deek. He is an al-Qaeda operative who has lived in Anaheim, California, for most of the 1990s. A former senior CIA official will later claim that Deek’s extremist connections were already “well established in the classified intelligence” by this time, and in fact, it will later be reported that Deek’s connections with al-Qaeda leader Abu Zubaida had been investigated since the late 1980s (see Late 1980s). Katz learns from intelligence reports that Deek has connections to a militant cell based in Montreal, Canada that includes Ressam. She suspects that Deek is coordinating al-Qaeda groups in North America. [LA Weekly, 9/15/2005; New Yorker, 1/22/2007] Deek regularly wires tens of thousands of dollars to overseas destinations. Business records show Deek was still in Anaheim as late as August 1998. The research team discovers Deek may have been visiting the US as late as September 1999.

Hisham Diab. Katz learns that Diab is Deek’s next door neighbor in Anaheim and she suspects the two of them have been operating a sleeper cell there (in fact, Diab’s wife had already repeatedly tried to warn the FBI about her husband, to no avail (see March 1993-1996). [LA Weekly, 9/15/2005]
She discovers that Deek and Diab have formed a charity front called Charity Without Borders (this group received a $75,000 state grant in 1997 to distribute fliers encouraging the recycling of used motor oil). [LA Weekly, 9/15/2005; Orange County Weekly, 6/15/2006]
Tawfiq Deek, Khalil Deek’s brother. Katz discovers that Tawfiq has presented himself as the Islamic Association for Palestine (IAP) spokesman in California. Katz calls the IAP the “Hamas front in America.” [Katz, 2003, pp. 167] Khalid Ashour, a Palestinian. He had lived in the same apartment building as the Deek brothers and Diab, and also worked with the IAP. But what most interests Katz is that he had been heavily involved in the Islamic Center of Tuscon in the early 1990s. The Islamic Center is important for the IAP but is also believed to be the focal point for al-Qaeda’s first base in the US (see 1994). Katz discovers that he had been arrested in 1991 trying to enter the US with a fake ID and border guards found handbooks of explosives and bombs in his car. In 1999, he had moved nearly half a million dollars out of the US despite holding a job that only paid $600 a week. [Katz, 2003, pp. 167-168]
Although Katz does not discover it at the time, another associate of the Deeks and Diab in Anaheim named Adam Gadahn will later emerge as a prominent al-Qaeda spokesman in Afghanistan (see Spring 2004).
Katz, Emerson, and other members of the Investigative Project on Terrorism will brief members of the National Security Council about what they learned on December 25, 1999, but no action will be taken against the suspects they have uncovered (see December 25, 1999).
