(London Daily Mail) Authorities say the remains of a firefighter killed in the September 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 Lieutenant 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.
