DNA experts have identified the remains of a 42-year-old brokerage executive who died on Sept. 11, 2001, and the medical examiner's office announced the discovery of 35 new human bone fragments in an area near ground zero.

The latest Sept. 11 victim to be identified, Edward Ryan, of Scarsdale, N.Y., was a vice president of Carr Futures with an office on the 92nd floor of the north tower of the World Trade Center.

His remains were found while sifting materials from a ramp once used to get to ground zero, said Ellen Borakove, a spokeswoman for the city's medical examiner. The ramp was dismantled several months ago as construction at the site progresses.

Ryan died along with 68 co-workers after apparently being trapped by debris that clogged stairwells in the burning tower that was hit by American Airlines Flight 11.

The families of 13 other Carr employees are still hoping the remains of their loved ones might be identified.

The office of the medical examiner is working with the Bode Technology Group, a DNA testing laboratory, to identify as many victims as possible.

Bode has patented a new methodology of DNA extraction that enables the creation of a DNA profile from much less sample material than was required only five years ago.

Following the discovery of human remains in an abandoned Con Edison manhole at the trade center site last October, more materials were collected from the access ramp and from another area bordering ground zero.

On Tuesday, 35 "potential" human remains were recovered, said Borakove, explaining that the term "potential" is used until DNA experts verify the exact nature of the remains. The human fragments are from a half inch to 4 inches long.

Of the 2,750 people who died at the World Trade Center, the remains of more than 1,100 have yet to be found.

A total of more than 20,000 human fragments recovered around the site have been entered into a database of DNA profiles of the victims, in hopes some may yet be identified.
