New Human Remains Found at Ground Zero

New York's Mayor Michael Bloomberg says city crews will go back to Ground Zero in search of human remains from September 11. On Wednesday, utility workers found remains as large as arm and leg bones near a site where victims' families meet yearly to read the names of their loved ones. Some 2749 people died in the attack on the World Trade Center and the search for remains went on for 9 months. Many have seen no evidence that their relatives died, in part because DNA was so damaged by heat, humidity and time. This week's discovery has created outrage.
