Mounir el Motassadeq was a member of the Hamburg sleeper cell that "planned and carried out" the September 11 attacks. A "close friend of 9/11 hijackers Mohamed Atta, Marwan Al-Shehhi and Ziad Samir Jarrah," reports the McClatchy News, el Motassadeq "had signed wills, taken over power of attorney for the hijackers and wired money for logistical support, including flight training." Yesterday, he was sentenced to 15 years for his conviction as an "accessory to murder for the 246 people who died on the four airliners," but not for the thousands murdered in the Twin Towers and the Pentagon. His 15-year sentence, the maximum allowable under German law, means el Motassadeq will serve (assuming he's not eligible for parole) a little over 22 days for each murder.
