Photo Gallery 'Clear and Present Danger'
Aafia Siddiqui, shown after her graduation from Massachusetts Institute of Technology. She spent more than 10 years studying at elite universities in the United States, eventually earning a PhD in neuroscience at Brandeis University.
The FBI considered her so dangerous that former Attorney General John Ashcroft placed her -- the only woman -- on his "Deadly Seven" list, after a tip from the Pakistani terrorist Khalid Sheikh Mohammed.
Fauzia Siddiqui claims "something is simply not right" about her sister Aafia's long disappearance. "There must have been a mistake."
Just after her reappearance and arrest in July 2008, Aafia appeared in a video with her face covered, and claimed the boy with her (left) was an adopted orphan. DNA tests proved him to be her natural son Ahmed.
Siddiqui was arrested in the Afghan town of Ghazni, suspected of planning a suicide attack. But she won't be tried on terrorism charges -- and she's now recovering from a bullet wound sustained in custody. Women in Islamabad, Pakistan, protest her treatment.
Attorney General John Ashcroft in May 2004: Siddiqui "constitutes a clear and present danger."
In the immediate aftermath of September 11, Siddiqui was regarded as al-Qaida's "Mata Hari" and its "female genius." Now her status is not so clear.
