At some point between the middle of 2001 and February 2002, the CIA appoints a new chief of the Sunni Extremist Group, the part of the Counterterrorist Center that is responsible for Alec Station, the CIA’s Osama bin Laden unit. Presumably this occurs in December 2001, when the group’s former head, Richard Blee, is made chief of station in Afghanistan (see December 9, 2001). However, this is not entirely certain. A 2011 book by FBI agent Ali Soufan will refer to the new group chief as “Alvin,” although this is apparently an alias. A 2007 book by former CIA Director George Tenet will refer to the chief as “Hendrik V.,” apparently a version of his real name. Hendrik V. will have been replaced as SEG chief by another official, Marty Martin, by March 2003. [Tenet, 2007, pp. 232, 251; Soufan, 2011, pp. 376,548] Hendrik V. previously served at the CIA station in Jordan, where he ignored crucial evidence during the investigation of the Millennium Plot in 1999 (see Late December 1999).
