(The oath was administered by the reporter. )

Mr. Cadigan.

I do.

Mr. Eisenberg.

Mr. Cadigan, the purpose for which we are here is to go into the facts of the assassination of President Kennedy, and in particular we have asked you to testify concerning analysis of questioned documents. Mr. Cadigan, could you state your full name and your position?

Mr. Cadigan.

James C. Cadigan. I am a special agent of the FBI, assigned as an examiner of questioned documents in the FBI laboratory in Washington, D.C.

Mr. Eisenberg.

And how long have you been in this field, Mr. Cadigan?

Mr. Cadigan.

Twenty-three and one-half years.

Mr. Eisenberg.

What was your training in this field?

Mr. Cadigan.

Upon being assigned to the laboratory I was given a specialized course of training and instruction which consisted of attending various lectures and conferences on the subject, reading books, and working under the direction of experienced examiners.
Upon attaining a required degree of proficiency, I was assigned cases on my own responsibility, and since that time I have examined many thousands of cases involving handwriting, hand printing, typewriting, forgeries, erasures, alterations, mechanical devices of all types, pens, paper, and ink. I conduct research on various problems as they arise and assist in the training of our new examiners.

Mr. Eisenberg.

Have you testified in Federal or other courts, Mr. Cadigan?

Mr. Cadigan.

Yes; in many Federal and State courts, and military courts-martial.

Mr. Eisenberg.

Mr. Cadigan, I now hand you Commission Exhibit No. 773, and I ask you whether you have examined that item.

Mr. Cadigan.

Yes; I have.

Mr. Eisenberg.

For the record, that consists of an application to purchase a rifle, addressed to Klein's Sporting Goods in Chicago. Mr. Cadigan, I now hand you an item consisting of a roll of microfilm labeled D-77, and ask you whether you are familiar with that roll of microfilm?

Mr. Cadigan.

Yes; I am.

Mr. Eisenberg.

That micro film will be marked Cadigan Exhibit No. 1.
(The article referred to was marked Cadigan Exhibit No. 1.)

Mr. Eisenberg.

Mr. Cadigan, was Exhibit No. 773 developed from a negative contained in Cadigan Exhibit No. 1?

Mr. Cadigan.

Yes; it was printed from that roll.

Mr. Eisenberg.

I now hand you Commission Exhibit No. 780, consisting of the Marine Corps file of Lee Harvey Oswald; Commission Exhibit No. 778, consisting of two letters extracted from Oswald's State Department file; Commission Exhibit No. 781, consisting of a passport application by Lee Harvey Oswald, dated June 25, 1963--at least "Passport Issued June 25, 1963"; and Cadigan Exhibit No. 2, consisting of a letter from Lee Harvey Oswald to John B. Connally, then Secretary of the Navy.
(The document referred to was marked Cadigan Exhibit No. 2.)

Mr. Cadigan.

This is in two parts.

Mr. Eisenberg.

In two parts, and the second part consists of a letter from Lee Harvey Oswald to a Brigadier General R. McC. Tompkins, dated 7 March 1962, and a group of documents, comprising photographs of the balance of Lee Harvey Oswald's State Department file, labeled Cadigan Exhibit No. 3.
(The documents referred to were marked Cadigan Exhibit No. 3.)

Mr. Eisenberg.

I ask you whether you have examined these various items.

Mr. Cadigan.

Yes; I have.

Mr. Eisenberg.

Mr. Cadigan, can you explain the meaning of the term "standard" or "known documents" as used in the field of questioned-document examination?

Mr. Cadigan.

Yes. Known standards are samples of writings of an individual which are known to be in his writing and which are available for comparison with questioned or suspect writings.
