Senator Cooper. What were the characteristics of the report that you heard, three reports, which made you believe that it was a shot from a rifle?

Mr. Baker. Well, they were too distinct, you know, to be—I have heard that pop from that motorcycle and I have heard rifle shots, and to me there was just a difference in them.

Mr. Belin. Officer Baker, did it appear to you that these sounds that you heard were from the same rifle or from possibly more than one rifle?

Mr. Baker. I would say they was from the same rifle.

Mr. Belin. Did it appear that the sounds all came from the same source?

Mr. Baker. Yes, sir.

Mr. Belin. With regard to the closeness of these sounds together, how fast they came, did it appear that it came from or that it could have come from a weapon that had to be operated by bolt action as opposed to a semiautomatic or an automatic weapon?

Mr. Baker. It seemed to me like you could either fire a semi or bolt action in about the same time.

Mr. Belin. Have you had occasion to use a bolt action rifle and fire shots quickly one after the other?

Mr. Baker. Yes, sir; I have.
