9/11 victim identified through DNA 13 years on

A man who died in the 9/11 attacks in New York has been formally identified for the first time more than 13 years after the tragedy.

New York City's Chief Medical Examiner's Office (OCME) announced today that they had identified through DNA 26-year-old Matthew David Yarnell from New Jersey.

Yarnell, an assistant vice president for technology at Fiduciary Trust International, was in the South Tower, the second building to be struck by a plane on September 11, 2001.

His remains were among those recovered in the original search for remains in 2001 and 2002, but were not identified until additional DNA testing.

The identification brings the total number of positively identified victims in the attack to 1,640 out of 2,753 people reported missing.

Almost 40 per cent of the victims remain unidentified.
