Two people killed in the September 11, 2001, terror attacks were identified this week by authorities, ahead of the twentieth anniversary of their passing, NBC News reported.

Dorothy Morgan, of Hempstead, New York, and a man whose name was withheld at the request of his family, were identified as the 1,646th and 1,647th victims of the attack.

The two are the first victims to be identified since October 2019, NBC added.

Approximately 40% of the victims still remain unidentified, authorities said.

Their remains were positively identified through "ongoing DNA analysis," a Tuesday statement from the New York City Office of the Chief Medical Examiner said.

The attacks, which targeted the Pentagon, Twin Towers, and an unknown fourth target presumed to be the Capitol or White House, left 2,977 dead.

In a statement, Dr. Barbara A. Sampson, the chief medical examiner, said, "Twenty years ago, we made a promise to the families of World Trade Center victims to do whatever it takes for as long as it takes to identify their loved ones, and with these two new identifications, we continue to fulfill that sacred obligation."

"No matter how much time passes since September 11, 2001, we will never forget, and we pledge to use all the tools at our disposal to make sure all those who were lost can be reunited with their families."
