Mr. Latona. It is very common, one of the most common methods of recording latent prints.
Mr. Eisenberg. Who did you get this exhibit, this lift from?
Mr. Latona. This lift was referred to us by the FBI Dallas office.
Mr. Eisenberg. And were you told anything about its origin?
Mr. Latona. We were advised that this print had been developed by the Dallas Police Department, and, as the lift itself indicates, from the underside of the gun barrel near the end of the foregrip.
Mr. Eisenberg. Now, may I say for the record that at a subsequent point we will have the testimony of the police officer of the Dallas police who developed this print, and made the lift; and I believe that the print was taken from underneath the portion of the barrel which is covered by the stock. Now, did you attempt to identify this print which shows on the lift Exhibit 637?
Mr. Latona. Yes; I did.
Mr. Eisenberg. Did you succeed in making identification?
Mr. Latona. On the basis of my comparison, I did effect an identification.
Mr. Eisenberg. And whose print was that, Mr. Latona?
