Few situations exist in which one can draw a parallel to the men and women who lost their lives on 9/11.

But, retired NYPD detective Michael Prate said one does stick out in his mind - the murder of Henryk Siwiak in Brooklyn during the last few minutes of that tragic day.

Siwiak, 46, a recent Polish immigrant, was supposed to be at his first night at a new job at a grocery store in Brooklyn.

He got on the A train and that's where he made a fatal error.
