Mr. Eisenberg. I am not sure I understand your reference to a minimum of 24 hours.
Mr. Latona. We have conducted tests with various types of materials as to how long it could be before we would not develop a latent print.
Mr. Eisenberg. Yes?
Mr. Latona. Assuming that the same print was left on an object or a series of similar prints were left on an object, and powdering them, say, at intervals of every 4 hours or so, we would fail to develop a latent print of that particular type on that particular surface, say, within a 24-hour period.
Mr. Eisenberg. So that is a maximum of 24 hours?
Mr. Latona. That is right.
Mr. Eisenberg. You would not care, you say, though——
Mr. Latona. No.
Mr. Eisenberg. To employ that here, but your experiments produced a maximum time of 24 hours.
Mr. Latona. Bear that out; yes. Like I say, undoubtedly this print was left on there—between the time that the print was left and the time that it was powdered could not have been too long a time. Otherwise, the print would not have developed with the clarity that it did.
