US prosecutors in Detroit are trying four men accused of an al-Qaeda plot. The men, Abdel-Ilah Elmardoudi, Karim Koubriti, Ahmed Hannan, and Farouk Ali-Haimoud, were arrested shortly after 9/11. They had been living in a Detroit apartment previously occupied by Nabil al-Marabh (see September 17, 2001). Yousef Hmimssa, a Moroccan national, had lived in the Detroit apartment with al-Marabh. When the FBI raided the apartment, they found fake immigration papers linking Hmimssa and al-Marabh, along with attack plans. [ABC News 7 (Chicago), 1/31/2002] Hmimssa will later be the key witness in the trial against the four arrested Detroit men (see June 2003-August 2004). The FBI later identify three other witnesses—a landlord, a Jordanian informant, and a prison inmate—who linked the four arrested men to al-Marabh (see December 2002). The Detroit prosecutors want to charge al-Marabh as a fifth defendant. However, Deputy Assistant Attorney General David Nahmias prevents them from doing so. He says, “My understanding is that the only connection between al-Marabh and your case was an apparent misidentification by a landlord.” Additionally, memos written by Detroit prosecutors during the trial will later show that they believed the Justice Department was preventing them from introducing some of their most dramatic evidence in the trial. Lead Detroit prosecutor Richard Convertino will later say: “There was a series of evidence, pieces of evidence, that we wanted to get into our trial that we were unable to do. Things that would have strengthened the case immeasurably, and made the case much stronger, exponentially.” For instance, the FBI had learned before the trial that al-Qaeda leader Ibn al-Shaykh al-Libi told US interrogators after his capture that bin Laden had authorized an attack on the US air base in Incirlik, Turkey. The FBI also found sketches in the Detroit apartment of what they believed was the same base. The prosecutors wanted to link this evidence to testimony by the al-Libi, but he was handed over to Egypt to be tortured and prosecutors were not able to interview him or use him as a witness (see January 2002 and After). Turkish authorities will later claim that their own evidence indicates bin Laden did authorize an attack on the base at one point. Detroit prosecutors also later complain that the lone Justice Department lawyer sent to help with the case had no intention of helping with the trial, and spent most of his time in Detroit staying in his hotel room or playing basketball. [Associated Press, 8/9/2004] In 2002, Chicago prosecutor Patrick Fitzgerald is also prohibited from charging al-Marabh with any crime (see January-2002-December 2002).
