July 26 (UPI) -- New York City's chief medical examiner said improved DNA testing has allowed authorities to definitively identify another victim of the Sept. 11, 2001, terrorist attacks.
The attacks killed nearly 3,000 people in New York City.
Johnson is also the first victim positively identified since last summer. He had worked as a security analyst at investment banking company Keefe, Bruyette and Woods on the 89th floor of the World Trade Center south tower.
"In 2001, we made a commitment to the families of victims that we would do whatever it takes, for as long as it takes, to identify their loved ones," Sampson said. "This identification is the result of the tireless dedication of our staff to this ongoing mission."
More than 1,100 victims remain unidentified.
