Mr. LATONA. Well, I was told--my information was simply that the Dallas Police Department had done so. I have no personal knowledge as to who did it, other than information that the Dallas Police had examined the weapon and they had found these visible marks on there, that they had developed the prints. Now, by what means they did it, I do not know, but I would assume they used a gray powder. Mr. DULLES. What was the purpose of putting the cellophane there? Mr. LATONA. To protect the prints while the rifle was intransit to the FBI. Mr. EISENBERG. Now, when you received it with the cellophane cover, what portion did it cover? Mr. LATONA. Closest to the trigger area. Mr. EISENBERG. On the trigger guard, closest to the trigger area? Mr. LATONA. That's right. Mr. EISENBERG. Was that on the right or left side of the weapon? Mr. LATONA. Left side. Mr. EISENBERG. And was there a print visible to you underneath the cellophane? Mr. LATONA. I could see faintly ridge formations there. However, examination disclosed to me that the formations, the ridge formations and characteristics, were insufficient for purposes of either effecting identification or a determination that the print was not identical with the prints of people. Accordingly, my opinion simply was that the latent prints which were there were of no value. Now, I did not stop there. Mr. EISENBERG. Before we leave those prints, Mr. Latona, had those been developed by the powder method? Mr. LATONA. Yes; they had. Mr. EISENBERG. Was that a gray powder? Mr. LATONA. I assumed that they used gray powder in order to give them what little contrast could be seen. And it took some highlighting and sidelighting with the use of a spotlight to actually make those things discernible at all. Representative FORD. As far as you are concerned. Mr. LATONA. That's right. Mr. DULLES. Is is likely or possible that those fingerprints could have been damaged or eroded in the passage from Texas to your hands? Mr. LATONA. No, sir; I don't think so. In fact, I think we got the prints just like they were. There had, in addition to this rifle and that paper bag, which I received on the 23d--there had also been submitted to me some photographs which had been taken by the Dallas Police Department, at least alleged to have been taken by them, of these prints on this trigger guard which they developed. I examined the photographs very closely and I still could not determine any latent value in the photograph.
