I graduated from the following fingerprint schools: in 1945, the U.S. Naval Air Station; in 1948 I graduated from the Institute of Applied Sciences, which is a fingerprint school, fingerprint and identification school; in 1955 I graduated from the New York Police Fingerprint School at the police academy; and in 1958 I attended an advanced latent fingerprint course conducted by the FBI at the New York Police Academy. I am a fingerprint instructor for the New York Police Department Bureau of Criminal Identification and lecture at various hospitals relative to the proper techniques involved in footprinting the newborn. I am a qualified fingerprint expert and have testified in New York State and Federal courts, including court-martials, relative to all phases of fingerprints, palmprints, and footprints. Mr. EISENBERG. Could you venture a guess as to how many identifications you have been called upon to make in the course of your work? Mr. MANDELLA. General identifications, I suppose, it runs into many thousands. It is hard to pick a number. But it is certainly well into the thousands of examinations. Mr. EISENBERG. Mr. Chairman, may this witness be permitted to testify as an expert witness on the subject of fingerprints? Mr. DULLES. Yes; he may. Mr. EISENBERG. Mr. Mandella, did you at my request examine certain photographs of latent prints and compare them with photographs of inked or known prints to determine whether there were identities between the known and latent prints? Mr. MANDELLA. Yes; I did. Mr. EISENBERG. I hand you Commission Exhibits 656, 658, 659, 655, 657, 661, and 660. Could you briefly look through these and determine whether these are the photographs which you examined? As you finish an item, could you take a look at the Commission number and verify that you looked at the photographs in that Commission envelope? Mr. MANDELLA. Yes; I have examined the photographs contained in Commission Exhibit No. 656. Mr. DULLES. I wonder if you would just state the number, in each case, in each envelope? Mr. MANDELLA. In Commission Exhibit 656 there are 10 photos, 10 photographs. And I have also examined Commission Exhibit No. 658, which is one photograph. I also examined Commission Exhibit No. 659, which is two photographs. I have also examined Commission Exhibit No. 655, which is two photographs. I have examined Commission Exhibit No. 661, which contains three photographs. I have examined Commission Exhibit No. 660, which contains eight photographs. I have also examined Commission Exhibit No. 657, which contains three photographs. Mr. EISENBERG. 657 contains photographs of inked prints, is that correct? Mr. MANDELLA. That is correct. Mr. EISENBERG. The standard 10-finger chart and a right and left palmprint? Mr. MANDELLA. Yes. Mr. EISENBERG. Which you have been informed by me and you see on the writing on these charts are the prints of Lee Harvey Oswald? Mr. MANDELLA. That is correct.
