Forensic Identification
As of September 11, 2012, 2,752 death certificates were filed relating to the attacks. Of these, 1,588 (58%) were forensically identified from recovered physical remains. The Associated Press reported that the medical examiner's office possesses "about 10,000 unidentified bone and tissue fragments that cannot be matched to the list of the dead." Bone fragments were still being found in 2006 as workers prepared the damaged Deutsche Bank Building for demolition.
On April 17, 2013, five possible remains were recovered after being sifted at Fresh Kills on Staten Island. The medical examiner said evidence of a possible victim of the attacks was recovered as well two days later.
On June 21, 2013, the medical examiner's office identified its 1,637th victim, a 43-year-old woman, to its list of victims, as a result of DNA testing of debris collected from the site. By family request, her name was not released.
