(CNN) -- The remains of a firefighter killed in the September 11, 2001, terror attacks at the World Trade Center have been identified, the New York City Medical Examiner's office said Friday.
Lt. Jeffrey P. Walz, 37, was identified after authorities retested remains that were recovered in the months following the attack.
Ironworkers wait for the final piece of the One World Trade Center spire to be raised into position for attachment to the building in New York on Friday, May 10. The 408-foot spire brings the building to a height of 1,776 feet, making it the tallest in the Western Hemisphere.

Of the 2,753 people killed in the attack, more than 1,100 people have not had remains identified, according to Barbara Sampson, acting chief medical examiner.
More than 8,200 bone samples and additional samples require DNA testing, according to a report released by Sampson.
Walz, who was last seen in the north tower of the World Trade Center, was survived by a wife and a son, according to an obituary in the Staten Island Advance.
