His colleagues marvel at Vram S. "Ned" Nedurian's efficiency and expertise.
"He handles twice as many cases as any of the other attorneys," said John F.X. Reilly, a deputy Delaware County district attorney.
But what is perhaps most remarkable about Nedurian is his age: 90.
And on Friday, he was at the center of a closely guarded secret in the Delaware County District Attorney's Office.
For weeks, colleagues had been planning his 50th work-anniversary celebration. Late Friday morning, 200 friends, attorneys, judges and coworkers jammed into the council meeting room to honor Nedurian, who thought he was there to attend a mandatory staff meeting.
