Mr. Rankin. That is all right, go right ahead.

Mr. Curry. I said what was that, was that a firecracker, or someone said this. I don't recall whether it was me or someone else, and from the report I couldn't tell whether it was coming from the railroad yard or whether it was coming from behind but I said over the radio, I said, "Get someone up in the railroad yard and check."

And then about this time. I believe it was motorcycle Officer Chaney rode up beside of me and looking back in the rear view mirror I could see some commotion in the President's car and after this there had been two more reports, but these other two reports I could tell were coming behind instead of from the railroad yards.

Mr. Rankin. What do you mean by reports?

Mr. Curry. Sharp reports as a rifle or a firecracker, and looking in the rear view mirror then I could see some commotion in President Kennedy's car.

Mr. Rankin. You could distinctly hear and tell that the two later reports were from behind?

Mr. Curry. Behind.

Mr. Rankin. Rather than front?

Mr. Curry. That is right.

Mr. Rankin. You weren't sure whether the first one was from behind or in front?
