In 2009, the younger Zazi confessed he was plotting to bomb the New York City subway system. He said he returned from Pakistan to the family’s Denver-area home to practice making homemade bombs.

The younger Zazi then drove to New York with plans to attack the subway system. Instead, he learned he was being watched by the FBI and fled back to Colorado.
