The remains of a man killed during the terrorist attack of World Trade Center on 9/11 have been identified nearly 16 years after the terror attacks, medical examiners confirmed on Monday. However, the name of the victim was withheld on family’s request.
Medical examiner’s office makes use of DNA testing and other means to match bone fragments to the 2,753 people killed by the hijackers who crashed airplanes into the trade center’s twin towers on Sept. 11, 2001.
Remains of 1,641 victims have been identified so far which means upto 40 percent of those who died are yet to be identified by the remains.
As DNA testing advanced, so has the multimillion-dollar effort to connect more than 21,900 bits of remains to individual victims. Few full bodies were recovered after the giant towers burned and collapsed, and the effects of heat, bacteria and chemicals such as jet fuel made it all the more difficult to analyze the remains.
The medical examiner’s office came to use a process that involves pulverizing the fragments to extract DNA, then comparing it to the office’s collection of genetic material from victims or their relatives. Most of the DNA profiles generated belong to previously identified victims.
In some cases, scientists have gone back to the same bone fragment 10 or more times, hoping new technology will provide answers.
The 9/11 airliner attacks killed a total of nearly 3,000 people in New York, at the Pentagon and near Shanksville, Pennsylvania.
