Usually, the great thing about FR is the sharing of information, the getting at of the real 'truth'. I do not trust those that claim to have the 'truth' but are unwilling to prove it. They are either being snobbish, hoarding it in hopes it gives them 15 minutes of fame, or they don't have the truth.
Is there some reason one of you can't post the specific information on the stain in her underwear, since it seems to be so important ?
A. A pair of underpants. Q. With regard to the underwear, where were those underwear from
A. They were collected from the victim's bedroom.
A. Yes, I was.
Q. How did you obtain a DNA profile from that underwear?
A. I went to an area on the underwear which would commonly be a collection point for biological material. In particular, on this there was a yellowish stain that was observed on the inside crotch area of the underwear. It would be a natural area where drainage would occur from a vaginal area.
Q. Is that a source of genetic, that is biological material, that you have obtained or others have obtained from like samples in the past?
A. Yes, it is.
Q. Is that a fairly common source, for example, in sexual assault cases, for example?
MR. FELDMAN: Objection. Relevance.
THE COURT: Overruled.
THE WITNESS: Yes, it is.
17 BY MR. CLARKE:
Q. Now, in particular, you obtained results from all five of these items, the carpet stain, the jacket stain, the two samples from Brenda and Damon Van Dam, and from the underwear; is that correct?
A. That's correct.
Q. Did you then make comparisons of those results?
A. Yes, I did.
Q. With what results?
A. That the stain from the carpet and the stain from the jacket were of a similar source or highly likely from the same source as the source of the DNA on the inside crotch area of the underwear. I also determined that those three items could also be the result of a biological offspring of Brenda Van Dam and Damon Van Dam.
Q. All right. Could you tell us what you mean by that last portion in terms of the "could be from a biological offspring?" What do you mean by that?
A. DNA is inherited from your biological parents. You get half of your DNA from your mother and half from your father. And in the cases where there isn't a known reference sample available, a lot of times biological parents references are used. Their DNA is tested and their types are observed, and if it is compared to an unknown or to a secondary reference, like the underwear is, the -- there are types that are developed, determine if those types could have been the result of DNA passed on from a biological mother and father.
Q. So is it correct then that your DNA analysis of the parents' DNA was consistent with an offspring of those parents having left those genetic profiles in the stain found in the underwear?
A. That's correct.
Q. And is it also correct that the profiles from the carpet stain, the jacket stain and the underwear stain all matched each other?
A. Yes, they do.
