Mr. Greer. He was sitting there in the front. No, sir; I don't know what his action was then. I was watching the overpass, I wasn't looking his way.
Mr. Specter. When you were watching the overpass at that time, did you observe anything on the overpass?
Mr. Greer. Not that I can remember now.
Mr. Specter. Did you observe that there was no one present on the overpass?
Mr. Greer. My recollection, there may have been a police officer up there. It is vague to me now everything that I had seen at that time.
Mr. Specter. Do you know what Mr. Kellerman was doing at the time of the third shot?
Mr. Greer. No, sir; I couldn't say what he was doing.
Mr. Specter. Was there any radio communication between your automobile and any of the other automobiles?
Mr. Greer. Yes, sir.
Mr. Specter. Who made that radio communication?
