NAJIBULLAH ZAZI. Born in Afghanistan, Mr. Zazi moved with his family to New York City in 1999 and he became a legal US resident. Court documents allege that in 2008 he traveled to Afghanistan to join the Taliban, though he was recruited by Al Qaeda. He returned to the US in January 1999, moved to Denver, and in September 2009 was arrested for plotting to blow up New York’s subways with homemade bombs. He pleaded guilty in early 2010 to conspiring to use weapons of mass destruction, conspiring to commit murder, and providing support to a terrorist organization. In this September 2009 photo, Zazi, center, is escorted off an New York Police Department helicopter. He faces a possible life sentence.
