Get a man on top of that triple underpass and see what happened up there.

I heard a sharp report. We were near the railroad yards at this time, and I didn’t know—I didn’t know exactly where this report came from, whether it was above us or where.

Mr. CURRY. . . . we heard this first report, I couldn’t tell exactly where it was coming from. . . . I thought at first that perhaps this was a railroad torpedo... 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 as 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. You weren’t sure whether the first one was from behind or in front?
Mr. CURRY. I couldn’t tell because perhaps of the echo or the—...
REPRESENTATIVE FORD. Did you get this order over the PA system before the second or third shots?
