Khalid Sheikh Mohammed, the mastermind behind 9/11, is identified by an al Qaeda captive from a photograph and labeled an “associate” of Osama bin Laden.
He is subsequently indicted by a federal grand jury the next month. The FBI and U.S. Attorney do not really know who KSM is, other than as a financier of the 1993 World Trade Center attack and an accomplice in Ramzi Yousef’s activities in the Philippines. The indictment is sealed—secret—only to be opened once KSM is in custody.
