Looking for a Music Cue...

This is a long shot, but does anyone know what the piece of music is that's used in the film around 1:05 - 06?

It's a very brief, quite haunting cue that can be heard after Chow Yun-Fat and Dean Shek are chased into a warehouse during the New York scenes, when Shek starts muttering to himself about his daughter as Chow re-loads his automatic and looks on, troubled.

It's doesn't seem to be any of the original Joseph Koo stuff, and I've listened to what I can of the Jerry Goldsmith and Garry Chang borrowed scores, and it doesn't sounds like those either.

I only ask as there seem to be some real 'ABT' soundtrack experts on here!
