May 2, 2011 -- Osama Bin Laden is dead – but what has become of the other men responsible for 9/11? While 19 hijackers were among the nearly 3,000 people who died in the Sept. 11, 2001 attacks, many of those said to be responsible were nowhere near Washington or New York that morning. Some of the prime actors, like Osama, have been captured or killed, while others remain at large nearly ten years later.
