Mr. Brennan. Not on that floor.

There was no other person on that floor that ever came to the window that I noticed.

There were people on the next floor down, which is the fifth floor, colored guys. In particular, I only remember two that I identified.

Mr. Belin. Do you want to mark the window with the circle that you believe you saw some Negro people on the fifth floor. Could you do that with this marking pencil on Exhibit 477, please?

Mr. Brennan. The two that I identified, I believe, was in this window.

Mr. Belin. You want to put a "B" on that one?

Now, after you saw the man—well, just tell what else you saw during that afternoon.

Mr. Brennan. Well, as the parade came by, I watched it from a distance of Elm and Main Street, as it came on to Houston and turned the corner at Houston and Elm, going down the incline towards the railroad underpass. And after the President had passed my position, I really couldn't say how many feet or how far, a short distance I would say, I heard this crack that I positively thought was a backfire.

Mr. Belin. You thought it was backfire?

Mr. Brennan. Of a motorcycle.
