In 1996, German authorities begin investigating Mamoun Darkazanli, Mohammed Haydar Zammar, and four others for money laundering. The investigation apparently begins with Darkazanli and four unnamed others, and grows to incorporate Zammar. Darkazanli and Zammar are friends, and both are closely linked to the al-Qaeda Hamburg cell. The investigation is run by the Bundeskriminalamt (BKA), Germany’s federal crime investigation agency. In late 1998, Darkazanli will be increasingly suspected for various other terrorism ties. But in early 2000, chief federal prosecutor Kay Nehm will refuse to initiate terrorism investigation proceedings against him, saying there is not enough evidence. Prior to 9/11, German law makes it hard to convict anyone for a terrorism offense unless it can be proven they were involved in an attack on German soil. However, Der Spiegel will later note that while that was true, Darkazanli could have been charged with money laundering instead. The money laundering investigation will resume shortly after 9/11.
