NEW YORK (AP) - Authorities say remains of a firefighter killed in the Sept. 11 attacks have been identified more than 11 years after his death at the World Trade Center.
The city medical examiner's office said Friday that Lt. Jeffrey Walz's remains were collected before May 2002 but retested and identified only recently.
The 37-year-old Walz was an engineer before he decided to follow his father's example and become a firefighter in 1992.
He was killed in the trade center's north tower, leaving a wife and toddler son.
Some 2,753 people died in the attacks on the trade center. Friday's announcement brings the number of identified victims to 1,637.
New identifications are made periodically. Most recently, authorities said two weeks ago they had identified a 43-year-old woman. Her name wasn't released.
