Many remember the haunting photograph: A woman wearing business attire and pearls is covered head-to-toe in white dust, her hands held out helplessly before her, as she makes her way out of the World Trade Center's damaged North Tower on September 11, 2001. She survived that day, getting out before both towers of the trade center crumbled and killed 2,753 people in the deadliest terror attack on U.S. soil. But the woman in the photos, known to most as the "Dust Lady," died Tuesday, her family said. Marcy Borders was 42.
