Mohammed R.

Shortly after 9/11, US investigators are finally able to access prisoner Zacarias Moussaoui’s belongings. A German cell phone number is found in his address book. In Germany, cell phone buyers must present a passport or other official identification, so German police quickly discover that the number belongs to Karl Herweg of Dusseldorf, Germany. Looking at phone records, it is discovered that in the weeks before 9/11, Herweg called Mounir El Motassadeq, Zakariya Essabar, and Mohammed Haydar Zammar, all believed to be members of the al-Qaeda cell in Hamburg, Germany, along with a few of the 9/11 hijackers. Additionally, Herweg called “Mohammed R.,” who remains publicly unknown but is believed to be a key 9/11 suspect. [Chicago Tribune, 2/25/2003] (Note that if this is the correct first name and initial, it could be a reference to Mohammed Rajih, a Yemeni whom German authorities will investigate for terrorist ties at some point before 2005, and who has links to some Hamburg cell figures—see 1998.) [Vidino, 2006, pp. 256] Herweg also called a satellite phone probably used by al-Qaeda leaders in Afghanistan. However, police learn that no one in Dusseldorf has the name “Karl Herweg.” There is a couple living next door to the bogus address with the last name of Herweg, but they have no children and have never heard of any Karl Herweg. Police begin tapping Herweg’s phone. But when no new calls are made or received by early November 2001, the surveillance is discontinued. However, phone records show that at least one call is made with the phone afterwards. Herweg’s actual identity and his relationship to Moussaoui and the Hamburg cell will remain a mystery. In 2003, the Chicago Tribune will call Herweg “one of the most important figures in the continuing mystery that is Sept. 11.” [Chicago Tribune, 2/25/2003]
