Mr. Eisenberg. Are your marks on these bullets?
Mr. Cunningham. Yes, they are.
Mr. Eisenberg. For the record, I would like to state these four bullets were recovered from the body of Officer Tippit.
When did you receive these bullets, Mr. Cunningham?
Mr. Cunningham. The Q-13 bullet was delivered to the Laboratory the first time on the morning of November 23d, and it was delivered to the Laboratory by Special Agent Vincent Drain of the Dallas office of the FBI.
Mr. Eisenberg. And the remaining bullets?
Mr. Cunningham. By the way, it was returned to Dallas, and then it was returned to the Laboratory, delivered again by Special Agent Vincent Drain, of the Dallas office, also, Special Agent Warren De Brueys. They delivered our Q-13 a second time on November 27th.
Representative Ford. When you say "our," what do you mean by "our"?
Mr. Cunningham. In other words, to facilitate reporting in the Laboratory, we usually give these items a Q or a K number. A Q number is a questioned item, like a bullet from a body, and a known is a gun, the K is a known, like a weapon.
That is for reporting purposes. But since this case began, we have so much evidence, and we have received so much evidence, it was considered practical to reassign a C number by us—like Mr. Eisenberg said, they are C-253, C-262, and C-251. They also have a Q number. Q-13 is C-13. That is the reason why I said "our" Q-13.
