Icons of 9/11: Where Are They Now?

In the weeks after Sept. 11, 2001, some iconic photographs emerged of grief. On this sixth anniversary, ABC's David Muir reports on what has happened to some of these people, including Melodie Homer, a young wife who received a flag for her husband LeRoy Homer Jr.,.who was one of the pilots on United Flight 93. "I remember thinking, if I didn't take the flag, then it wouldn't be real," she said.
