A new DNA analysis process helps identify the remains of the victims of the terrorist attacks of 11 September 2001, according to a New York-based law enforcement agency.
For the future, the human remains were preserved
The New York bombings officially had 2753 victims, but the remains of more than a thousand people could not be identified.
The New York Law Enforcement Office decided in 2001 to preserve the remnants, hoping technological evolution over time would allow the identification of the victims, bringing peace to the bereaved families.
Thanks to the technological advances in recent years, the remains of five victims have been identified since 2013.
There was a breakthrough in identifying victims
Through their new method, scientists have recently identified a new victim:
26-year-old Scott Michael Johnson worked as a financial expert in one of the twin towers of the World Trade Center (WTC), which had been dropped by a terrorist attack.
Mark Desire, and his associates at the Office’s Criminal Laboratory, have taken on the new fragments of fragments that have been tested on a number of occasions, so far unsuccessful.
According to Desire, the so-called World Trade Center Protocol is also used to identify victims of train and aircraft accidents and terrorist attacks in Argentina, Canada, the Republic of South Africa and other parts of the world.
They make the bones fragile with liquid nitrogen
The essence of this method is that practitioners first cleanse the bone, crumble, add chemical substances and then try to extract the DNA from the incubated sample.
The more you manage to crush the bone, the more likely it is to recover DNA from the damaged material.
The practitioners have now added a new step: they place the bone in liquid nitrogen, which becomes fragile and shake until it crushes into dust.
