KSM told interrogators that a woman named Aafia Siddiqui, a U.S. visa holder who has lived in the United States for a decade, rented a post-office box to help Khan establish his U.S. identity. Siddiqui was supposed to support “other AQ operatives as they entered the United States,” according to the Feds’ description of the plot. Siddiqui’s estranged husband, identified by informed sources as Mohammad Amjan Khan, had purchased body armor, night-vision goggles and a variety of military manuals to send to Pakistan. He apparently returned these items after being interviewed by the FBI. Both Siddiqui and Khan were described as “medical professionals.” Siddiqui fled to Pakistan, where she was reportedly arrested.

Wasn't there a person arrested on 911- or maybe it was one of the 911 hijackers - who had used a woman's bank account in the DC area? It's been a long time since I've read that article but it was, I think, associated with some arrests in DC on 911 or maybe the next day. I wonder if the woman was Siddiqui?
