Iraq hostage crisis
On November 26, 2005 Fox was taken hostage along with three other members of the CPT team in Iraq. The captors threatened to kill all hostages unless the United States freed all Iraqi prisoners held in the US and Iraq by December 8, 2005. They later extended this deadline to December 10, 2005. On December 10, 2005, Katherine Fox issued a statement saying that she and her father believe the Iraqi people have legitimate concerns about the United States' presence in Iraq, but "these grievances, however, will not be resolved by taking my father's life." On March 7, 2006 Al Jazeera aired a tape which showed the other three hostages, but did not show Fox. On March 10, 2006 the U.S. State Department announced that Fox's body had been found on a garbage heap in Baghdad, shot through the head and chest. According to Iraqi police, his hands were bound and signs of torture were evident. However, conflicting reports from an anonymous Iraqi police official and members of CPT stated that there were no signs of torture. The autopsy report was not released. On March 23, 2006 the remaining hostages were freed by multinational forces. Muharib Abdul-Latif al-Jubouri is believed to have personally killed Fox. Al-Jubouri was killed in May 2007.
