9/11 victim identified as man from Long Island with help of DNA technology

NEW YORK -- Well over two decades since the terror attacks of September 11, 2001, the unyielding DNA testing by the New York City Office of the Chief Medical Examiner paid off with a positive identification of another victim.

The medical examiner's office announced Thursday it has positively identified John Ballantine Niven of Oyster Bay, a town in Long Island, New York. He is the 1,650th 9/11 victim identified.

"While the pain from the enormous losses on September 11th never leaves us, the possibility of new identifications can offer solace to the families of victims," said New York City Mayor Eric Adams. "I'm grateful for the ongoing work from the Office of Chief Medical Examiner that honors the memory of John Ballantine Niven and all those we lost."

The new identification was made through ever-advancing DNA testing of remains recovered in 2001, the medical examiner's office said.

"Our solemn promise to find answers for families using the latest advances in science stands as strong today as in the immediate days after the World Trade Center attacks," said Chief Medical Examiner Dr. Jason Graham. "This new identification attests to our agency's unwavering commitment and the determination of our scientists."
