How DNA science assisted the identification process following September 11th, 2001



Over 2,700 people were killed on September 11, 2001. 

Adding even more sorrow to the tragic events in New York City that day was the fact it took months – and in some cases years – for families to receive final closure. 

Due to the damage caused at Ground Zero from  water, mold, bacteria, fire and jet fuel, the challenge of identifying the remains was very difficult, according to Mark Desire of the Office of the City Medical Examiner in New York City. 

“Fire, water, sunlight and mold and bacteria and jet fuel — all of these things destroy DNA, and I just mentioned everything that was present at Ground Zero, so this was extremely challenging,” he told The New York Post in an interview. 

The Post article details the incredible science that went with the process of identifying the remains, including a way to draw blood from bone.
