Quazi Mohammad Nafis was a 21-year-old student living in Queens, New York, when the US government helped turn him into a terrorist.

His transformation began on July 5, when Nafis, a Bangladeshi citizen who'd come to the United States on a student visa that January, shared aspirations with a man he believed he could trust. Nafis told this man in a phone call that he wanted to wage jihad in the United States, that he enjoyed reading Al Qaeda propaganda, and that he admired "Sheikh O," or Osama bin Laden. Who this confidant was and how Nafis came to meet him remain unclear; what we know from public documents is that the man told Nafis he could introduce him to an Al Qaeda operative.

It was a hot, sunny day in Central Park on July 24 when Nafis met with Kareem, who said he was with Al Qaeda. Nafis, who had a slight build, mop of black hair, and a feebly grown beard, told Kareem that he was "ready for action."
