Mr. Eisenberg. That is to say that the 100 hairs would be different from each other?
Mr. Stombaugh. Yes, sir.
Mr. Eisenberg. Is your experience, therefore, that the hairs of different individuals do not match in observable microscopic characteristics—within the basis of your experience?
Mr. Stombaugh. Within the basis of my experience, I have examined thousands of hairs and I have never found Caucasian hairs from two different individuals that match.
Mr. Eisenberg. Now, when you say that, Mr. Stombaugh, have you been presented with hairs in your laboratory from Caucasian individuals which you knew before the examination came from two or more individuals?
Mr. Stombaugh. Yes.
We have obtained samples of hairs from a hundred different people, and would select one hair, give it to an examiner and ask who it originated from, and invariably he would be able to find in the hundred different samples the individual the hair originated from.
Mr. Eisenberg. Now, when a specimen comes into your laboratory, does it frequently come in—and I am talking now about specimens that come in from a crime—does it frequently come in such, so that you have two specimens, two or more specimens, which you know before you begin are from two different people?
Mr. Stombaugh. Yes.
Mr. Eisenberg. You are told before you begin that they come from two different people?
