Thank you, your Honor. Could we have the Bronco photo and result board up there next?
Oh. Item 48, 47 and 50. Could we change boards now, Mr. Fairtlough, to the Bronco photo and result board, exhibits 172 and 260? And I'd like to have marked as 275-D, copy of gel AG174.
While we're getting the board set up, could you describe the samples that are on 275-D, which is your AG174?
Yes. These are, once again, the reference samples from three individuals, O.J. Simpson being a 24, 25, Ronald Goldman being a 24 homozygote and Nicole Brown being an 18, 18, an 18 homozygote.
Okay. And now, do we lose a little fidelity when we project these copies up on the screen?
Okay. How do you visualize these things when you're looking for them for the first time to interpret them and write the report?
I look at the actual gel after it's been dried down and I do my interpretation based on--or I write the results that I see at the time on a run sheet and then also a second reader reads those gels. That can be done at a different--or later date though. These are blue copies. And first of all, the blue copy is--represents what the actual gel--what was present on the actual gel. But when you project it up here, you tend to lose--it's not as sharp and it's not as dark. But I think when you see these printouts, you'll be able to see it.
Okay. Item no. 30, which was taken from the Bronco center console, could you tell us what results you obtained from that sample?
Okay. And what about Bronco 31, the other center console sample that was provided to you? What results or what bands did you see there?
Now, what conclusion can you reach on the 24, 25 with respect to the possibility there's a mixture there?
Well, the interpretation had to be based also on the results of the DQ-Alpha. And by looking at the DQ-Alpha results in conjunction with these D1S80 results, it was determined it was a mixture. By just looking at the D1S80 results alone, mixture can't be determined.
Okay. But if there were a mixture of Mr. Simpson and Mr. Goldberg, would it look just like what you see in 31, the console stain?
Okay. Why don't you move on to Bronco 293, which was from the driver's side carpet? Can you tell us what results you obtained from that sample?
Okay. On this sample, there's a single-banded pattern, and it's an 18.
KEY QUOTEOkay. And who was that consistent with? Could we make that 18 a different color if you would?
Could you put a green arrow over there by Nicole Brown's single-banded pattern from her reference sample?
Okay. 305 is a mixture and there are three bands present, the 24, the 25 and an 18.
It's slightly difficult to see that 18 from here. But when you see the actual blue copy, you'll be able to visualize it.
Okay. Could you put a green arrow down by the 18 in sample 305, the Bronco sample 305?
And then--and then--and then let's go back--let's go back to the red 24, 25 bands that you saw.
Okay. And you've marked 24 and 25. Now, you said we know that's a mixture. How do you know that?
You know it's a mixture because there are more than two bands present. There are three bands present in that sample, a 24, a 25 and also the 18. And also, the relative intensities of the band. The 18 allele's much weaker than the 24 and 25 alleles.
KEY QUOTEYes. It means the amount of the 18 allele is less than the amount of the 24 allele or the 25 allele.
And is there something about the way this whole kit is designed that will help you when you see something faint like that interpret it?
Yeah. Both the kit and also the in-laboratory evaluation that the Department of Justice did for D1S80, we optimize the system so when you have a neat bloodstain, meaning a--or DNA, a sample from one individual, that you'll get equal intensity of the two--the two bands. So in this case, what you could see is, there's not equal intensity of those bands and there's a weaker component down there at the 18.
And are the results that you produced for 305 based on D1S80 alone, are they consistent with a mixture from the three reference samples in this case, Mr. Simpson, Mr. Brown and--Mr. Goldman and Miss Brown?
Yes. None--those--neither or none of those individuals can be excluded as a possible source of the DNA in the Bronco stain, no. 305.
KEY QUOTEAnd the DQ-Alpha results also contribute more information to that mixture; is that true?
All right. Tell you what. Let's take our break five minutes early because we'll have to do another set of exhibits here. Ladies and gentlemen, please remember all of my admonitions; don't discuss this case amongst yourselves, don't form any opinions about the case, don't conduct any deliberations until the matter has been submitted to you. Also, do not allow anyone to communicate with you with regard to the case. And we'll take a break for about 15 minutes. All right. We'll stand in recess.
On this sample, there's a single-banded pattern, and it's an 18... That's consistent with Nicole Brown... Yes, it is [inconsistent with Mr. Simpson and Mr. Goldberg].
You know it's a mixture because there are more than two bands present. There are three bands present in that sample, a 24, a 25 and also the 18.
Neither or none of those individuals can be excluded as a possible source of the DNA in the Bronco stain, no. 305.
The 18 allele is much weaker than the 24 and 25 alleles... It means the amount of the 18 allele is less than the amount of the 24 allele or the 25 allele.
