New York scientists use new DNA tools to identify 9/11 victims

New DNA analysis techniques are helping identify more victims of the attacks on the World Trade Center on Sept. 11, 2001, scientists in the office of New York City's chief medical examiner said on Thursday. Although the death toll after two hijacked airliners crashed into the Twin Towers was 2,753, the remains of more than 1,000 people remain unidentified, to the dismay of their grieving families.
