Before he was captured, Khalid Shaikh Mohammed was plotting attacks against bridges, apartment buildings and hotels in New York, according to documents seized from his apartment, as well as notes taken from his pockets. Authorities are now searching for two accomplices in New York City, as well as a third person who probably lives in suburban Westchester or Putnam County. It's known that al-Qaeda has already done surveillance on U.S. bridges, including the Brooklyn Bridge. "It's a race against time to thwart attacks that have already been planned," says former FBI analyst Matthew Levitt.
Mohammed studied engineering at North Carolina Agricultural and Technical State University in the 1980s, so he has the necessary expertise. "There's a lot of damage an engineering graduate could do with this specialized information, and all engineering students have it," says William Craft, a professor of engineering at the university.
