i sealed off the area, and i held off the trains until they could be examined, and there was some transients taken on at least one train.
nothing that i can recall.
yes sir, traffic had been cut off into the area since about 10, but there were three cars came in during this time from around noon till the time of the shooting.  the cars circled the parking lot, and left like they were checking the area, one of the drivers seemed to have something he was holding to his mouth.  the last car came in about 7 to 10 minutes before the shooting, a white chevrolet, 4-door impala, muddy up to the windows.
towards the underpass, i saw two men standing behind a picket fence.  they were looking up towards main and houston and following the caravan as it came down. one of them was middle-aged, heavyset. the other man was younger, wearing a plaid shirt and jacket.
there were two other men on the eastern end of the parking lot. each of 'me had uniforms.
at the time of the shooting there seemed to be some commotion.  i just am unable to describe - a flash of light or smoke or something which caused me to feel that something out of the ordinary had occurred there on the embankment.
