June 2003-August 2004: Detroit ‘Sleeper Cell’ Members Found Guilty, Then Convictions Overturned After Allegations of Widespread Prosecutorial Misconduct

Verdicts are announced in a trial of four men who lived in a Detroit apartment on 9/11 that had previously been rented by al-Qaeda operative Nabil al-Marabh (see September 17, 2001). Abdel-Ilah Elmardoudi and Karim Koubriti are convicted of conspiring to provide material support to terrorists and also document fraud. Ahmed Hannan is convicted of document fraud. Farouk Ali-Haimoud is cleared of all charges. Justice Department officials, including Attorney General John Ashcroft, assert the men were in an al-Qaeda sleeper cell and had plans to attack targets in the US, Jordan, and Turkey. The verdicts are hailed as the first successful post-9/11 terrorism prosecution. [Washington Post, 12/31/2003] However, the case soon begins to fall apart. The judge learns the prosecution had withheld evidence in the case, and in December 2003, orders an internal Justice Department inquiry. In August 2004, the inquiry asks the judge to throw out the convictions because of prosecutorial misconduct, which he does. For instance, it is revealed that the only witness in the trial, Youssef Hmimssa, told a fellow prisoner that he had made up all his evidence against the defendants. But the prosecution kept this information, and much more that was potentially damaging to their case, from the jury. The Washington Post later reports that the inquiry concludes “the prosecution stuck doggedly to its theory in defiance of plausible explanations and advice from other US government officials. Records suggest prosecutors withheld evidence that cast doubt on their conclusions, even when ordered by superiors to deliver documents to the defense.” By late 2005, it will be reported that a federal grand jury is investigating whether the lead prosecutor, Richard Convertino, or anyone else should be indicted. Convertino meanwhile will sue Ashcroft and other Justice Department superiors, accusing them of mismanaging the case and retaliating against him for testifying critically about the Justice Department before Congress. [Washington Post, 12/31/2003; Associated Press, 8/30/2004; Washington Post, 11/20/2005] But Convertino will later be found not guilty of withholding evidence during the trial. Furthermore, it will be revealed that key evidence withheld from the defense actually would have strengthened the prosecution’s case, not the defense case. The Associated Press will later comment that a new analysis of the evidence suggests that there may have been a Detroit sleeper cell after all (see November 1, 2007).
