COUNTY OF DALLAS
SUPPLEMENTARY INVESTIGATION REPORT
I had just looked out the window of the radio room facing Main St and watched the Presidential parade pass and as it turned the corner onto Record I looked over in that direction but was unable to see any of the vehicles from my location and about that time I heard three loud reports evenly spaced which I presumed to be rifle or shotgun blast. I looked at the time on the radio panel and it was about 40 seconds after 12:30pm as I was calling Dallas PD on the hot line and I asked the operator that answered if anything had been reported and she said no I told her that I heard what I believed to be three shots and she thought I was kidding. At that time all the traffic officers at the intersection of Main and Record started running and some were on their motorcycles with red light and siren wide open headed in the direction of the railroad area north of Elm St. About that time DPD called advised that the President had definately been hit condition unknown and was enroute to Parkland and the hospital had been advised to stand by.
