Direct examination of Gary Sims (morning, part 3)

Witness: Gary Sims
Examiner: Rockne Harmon
Called by: Prosecution • Date: Wednesday, May 17, 1995 • Utterances: 324
DOJ DNA analyst Gary Sims walks through PCR and D1S80 DNA test results from nine blood samples taken from OJ Simpson's Bronco, methodically connecting each stain to the reference types of Simpson, Nicole Brown, and Ron Goldman. Several Bronco interior stains show Simpson's DQ-Alpha type (1.1, 1.2) as the dominant signal; the center console stains (303, 304, 305) show mixtures consistent with all three principals; and the driver's-side carpet stain (item 293) is consistent with Nicole Brown. Sims is notably careful throughout to distinguish between what the data shows and what conclusions he is willing to draw, particularly regarding Goldman's presence in ambiguous mixture samples.
1 (The following proceedings were held in open court, in the presence of the jury:)
2 THE COURT:

All right. Thank you, ladies and gentlemen. Please be seated. All right. Proceed, Mr. Harmon.

3 (Discussion held off the record between the Deputy District Attorneys.)
4 MR. HARMON:

Thank you, your Honor.

5 MS. CLARK:

Your Honor--

6 THE COURT:

Let's proceed.

7 MR. HARMON:

Can we proceed with that as we--

8 THE COURT:

Yes.

9 MR. HARMON:

Your Honor, at this point I would like to have marked as People's next in order--

10 THE COURT:

272.

11 MR. HARMON:

--272, a photo board showing item no. 9.

12 THE COURT:

No, not the photo board. The agreement was after lunch that was going to be taken care of.

13 MR. HARMON:

Oh, I misunderstood. I thought we would do that now.

14 THE COURT:

No. That wasn't done. Let's proceed.

15 MR. HARMON:

Okay. And we didn't address the sock board either, which is--

16 THE COURT:

Well, move on.

17 MR. HARMON:

Okay. Moving right on to exhibit no. 172, the Bronco photo board--your Honor, what time does the Court intend to break today?

18 THE COURT:

10:30.

19 MR. HARMON:

10:30. Okay.

20 MR. HARMON:

And could we show that in conjunction with the Bronco results board, which has been marked as exhibit 260.

21 (Brief pause.)
22 MR. HARMON:

Mr. Sims, while the photo board is being found, did the Department of Justice perform DNA analysis on LAPD item no. 24, which was marked as your no. 15?

23 MR. SIMS:

Yes.

24 MR. HARMON:

And did your department or your laboratory also perform DNA analysis on item no. 29 from the Bronco steering wheel, which you marked as DOJ 16?

25 MR. SIMS:

Yes.

26 MR. HARMON:

And did your department perform DNA analysis on item no. 30, LAPD item no. 30 from the center console of the Bronco, which you marked as DOJ DNA 17?

27 MR. SIMS:

Yes.

28 MR. HARMON:

And did your lab perform analyses on item no. 31 from the Bronco center console, which is your no. 18?

29 MR. SIMS:

Yes.

30 MR. HARMON:

And did your laboratory perform analyses on item no. 34 from the Bronco driver's sidewall which you marked as item 20?

31 MR. SIMS:

Yes.

32 MR. HARMON:

And did your department perform DNA analysis on item 293 from the carpet driver's side which you marked as your no. 29?

33 MR. SIMS:

Yes.

34 MR. HARMON:

And did your department perform DNA testing on item 303 from the center console which you marked as DOJ 52?

35 MR. SIMS:

Yes.

36 MR. HARMON:

Did your department, your laboratory, perform DNA testing on item 304 from the center console which us marked as DNA 53?

37 MR. SIMS:

Yes.

38 MR. HARMON:

And finally, from the Bronco, did your lab perform analysis on item 305 from the center console, which you marked as item 30?

39 MR. SIMS:

Yes.

40 MR. HARMON:

Okay. Let's go back to the top then. Item number--I'm sorry--24, which you marked as DNA 15, what sorts of tests did you perform on that sample?

41 MR. SIMS:

The tests--the test that was performed was DQ-Alpha typing, PCR DQ-Alpha typing.

42 MR. HARMON:

That is the only test you performed?

43 MR. SIMS:

Yes.

44 MR. HARMON:

What result did you obtain?

45 MR. SIMS:

The type was 1.1, 1.2.

46 MR. HARMON:

Okay. Is that result consistent with the known type of Mr. Simpson, the Defendant in this case?

47 MR. SIMS:

Yes, it is.

48 MR. HARMON:

Would you step to the board and remove the covers on item 24, your no. 15. Can you reach it?

49 (Witness complies.)
50 THE COURT:

Mr. Fairtlough.

51 MR. HARMON:

Okay. And that reflects DQ-Alpha 1.1, 1.2?

52 MR. SIMS:

Yes, it does.

53 MR. HARMON:

Was the Defendant excluded as a possible source of that stain?

54 MR. SIMS:

No, he was not.

55 MR. HARMON:

Could you remove that column.

56 (Witness complies.)
57 MR. HARMON:

Okay. And item no. 29, did you perform DNA testing on that sample?

58 MR. SIMS:

Yes.

59 MR. HARMON:

What results did you obtain?

60 MR. SIMS:

And again when you are saying "me," that is our laboratory.

61 MR. HARMON:

The laboratory, sure.

62 MR. SIMS:

On item no. 29--I'm sorry--this is--

63 MR. HARMON:

Item no. 29, your no. 16?

64 MR. SIMS:

Yes, yes, okay. That test was the DQ-Alpha test.

65 MR. HARMON:

And what were the results?

66 MR. SIMS:

The result was that we found mainly what we considered to be a 1.1, 1.2 with a weaker 4 allele.

67 MR. HARMON:

Okay. Would you remove the cover.

68 (Witness complies.)
69 MR. HARMON:

Are the results accurately depicted on 260, the exhibit board?

70 MR. SIMS:

Yes.

71 MR. HARMON:

And let's just talk about--this is one of the samples you sent extracted DNA to Cellmark from; is that correct?

72 MR. SIMS:

Yes.

73 MR. HARMON:

And as far as--the only test in common that you and Cellmark performed, if the chart is correct, is the DQ-Alpha testing; is that correct?

74 MR. SIMS:

That's correct.

75 MR. HARMON:

And you have described a weaker 4. What is the significance of seeing a 1.1, 1.2 weaker 4?

76 MR. SIMS:

With the weaker 4 allele--well, first of all, by my interpretation, I saw the 1.1, 1.2, which is consistent with the Defendant's own type, which is 1.1, 1.2. I noted the weaker 4 allele. And in my interpretation, because there was so little DNA in this sample, I was hesitant to make much of a conclusion of that weaker 4 as to who could be the source.

77 MR. HARMON:

Is this one of the ones you struggled with in terms of how to describe the significance or the conclusions of your results?

78 MR. SIMS:

Absolutely. It is a difficult interpretation.

79 MR. HARMON:

And it is clearly a mixture?

80 MR. SIMS:

Yes.

81 MR. HARMON:

And what is the significance of the low amount of DNA with respect to being able to draw a conclusion on this sample alone?

82 MR. SIMS:

On this sample alone my concern was with that very low level of DNA to begin with, and given that it is a mixture, I would be concerned that we may not detect one of the weaker alleles in a mixture.

83 MR. HARMON:

Now, when you say there was a low level of DNA to begin with, you performed some sort of quantitative analysis of the DNA?

84 MR. SIMS:

Yes, we did.

85 MR. HARMON:

And when you performed that sort of quantitative analysis, are you--is that a quanitation of the total amount of DNA that is in the mixture?

86 MR. SIMS:

Yes.

87 MR. HARMON:

But not the relative contradictions of the different sources?

88 MR. SIMS:

That's correct. In other words, we just knew the total DNA but we wouldn't know the breakdown of the mixture from that procedure.

89 MR. HARMON:

Okay. And is this one that you actually--it was difficult for you to describe in terms of what your conclusion was about who was excluded and who was not excluded?

90 MR. SIMS:

Yes.

91 MR. HARMON:

And is your--I'm going to ask you to describe it to the best of your ability the way you described your conclusion in your report. Do you have your report memorized in terms of how you concluded who was excluded and who was not on this stain?

92 MR. SIMS:

I--I don't have it memorized, but I have my report in front of me.

93 MR. HARMON:

Okay. Would it help to just read it over and do the best you can with that?

94 MR. SIMS:

yes. (Witness complies.)

95 MR. HARMON:

How did you describe your conclusions in terms of comparing your results with the reference samples in this case?

96 MR. SIMS:

Well, the main point I made again was that I saw this particular combination of 1.1, 1.2 as being the major component of this--of this pattern. And so I--from that I concluded that Mr. Simpson could not be excluded as a possible source of that sample.

97 MR. HARMON:

And is that clear, that that was not--you did not exclude him on this stain?

98 MR. SIMS:

Yes, that is--that is correct.

99 MR. HARMON:

Okay. Where did you go from there?

100 MR. SIMS:

Well, where I went from there was I saw this 4 by itself. I did not see Mr. Goldman's type in full which was the 1.3, 4, but I was hesitant to make an absolute exclusion of Mr. Goldman on that basis.

101 MR. HARMON:

Why?

102 MR. SIMS:

Well, what this kind of result tells me is that this is probably a good sample for additional testing, which is one reason we sent it to Cellmark because this information was just limited to my conclusion of Mr. Goldman. You know, at the same time I want to point out that I think is--I don't think it is proper for me to stand here and say, oh, yes, that 4 came from Mr. Goldman. That is not the kind of point I'm trying to make at all. The point I want to make is that when you are talking about absolute exclusions we said that we could not make a clear-cut exclusion of Mr. Goldman on that sample. I'm not suggesting for one moment that he is the source of that 4.

103 MR. HARMON:

So you can't exclude him?

104 MR. SIMS:

I could not make what I called a clear-cut exclusion.

105 MR. HARMON:

But you are not saying he is included either?

106 MR. SIMS:

That is exactly right. I think that would be very prejudicial.

107 MR. HARMON:

For that matter, can you tell us how many people could produce the combination of types that you see in your results?

108 MR. SIMS:

With just the major--major type--

109 MR. HARMON:

How many people--can you actually put a limit on how many people total could have contributed to that mixture?

110 MR. SIMS:

Well, it would be very difficult with interpreting that very weak 4 and not knowing what else may be there in the components.

111 MR. HARMON:

I guess my question is not clear. What is the maximum number of people that could have contributed the mixed results that you obtained, you alone obtained on that sample?

112 MR. SIMS:

Well, the maximum number, if you start thinking of all the different possibilities, that would certainly add up. I mean, you could have two people, for example, that are of the same type to contribute to a mixture.

113 MR. HARMON:

Let me just give you a general question. Without knowing the types of this group, could you exclude like the starting line-up of the L.A. Lakers?

114 MR. SIMS:

If I knew their types.

115 MR. HARMON:

But just by the number of them?

116 MR. SIMS:

No. It would be very difficult to make that kind of determination, but again, I can only speak to what I see. I can't--

117 MR. HARMON:

Sure. Are your results necessarily inconsistent with Cellmark's conclusion in any way?

118 MR. SIMS:

Oh, not at all. For example, if one wanted to say that Nicole Brown could be there because her 1.1 allele is present and she is a 1.1, 1.1, then certainly that is a possible combination.

119 MR. HARMON:

Okay. And given the way you've questioned it, do you feel there is any point to put Mr. Goldman's name in the "not excluded" column?

120 MR. SIMS:

I think this is sort of an asterisk situation. I don't feel comfortable putting him there. I certainly wouldn't feel comfortable putting him as a possible source. I think that would be incorrect.

121 MR. HARMON:

Okay. Let's move on to item no. 30 from the center console, no. 17.

122 MR. SIMS:

Okay.

123 MR. HARMON:

What results did the lab obtain on your analysis of no. 17?

124 MR. SIMS:

In that--on that particular sample we did 27 different PCR systems. We did the--the DQ-Alpha typing and will D1S80 typing.

125 MR. HARMON:

What were those results?

126 MR. SIMS:

The results were DQ-Alpha, the no. 30, was 1.1, 1.2, the D1S80 type was 24, 25.

127 MR. HARMON:

Were those results consistent with Mr. Simpson, the Defendant?

128 MR. SIMS:

Yes.

129 MR. HARMON:

Could you remove those two covers from item no. 30.

130 (Witness complies.)
131 MR. HARMON:

Okay. The board 260 accurately depicts the results that you just described?

132 MR. SIMS:

Yes.

133 MR. HARMON:

Let's move to item no. 31 from the center console, your no. 18. What sort of test did the lab perform on those?

134 MR. SIMS:

The lab performed DQ-Alpha and D1S80 tests.

135 MR. HARMON:

What were the results?

136 MR. SIMS:

The results were as follows: on the DQ-Alpha test we determined that there was mainly 1.1, 1.2 and we also saw what we considered to be a weaker application with 1.3 and 4 alleles.

137 MR. HARMON:

Okay. And the--how were you able to determine this stronger-weaker conclusion?

138 MR. SIMS:

When one is looking at one of these typing strips, one can see that there is a stronger contradiction, a stronger dot for particular types than for some of the other dots, and it is analogous to the process I was showing you on the RFLP. It is a different typing system, obviously, but it is the same idea about picking out what goes--what two alleles might go together because they are stronger and what two alleles or dots might go together because they are weaker.

139 MR. HARMON:

So sometimes you can sort them out by the relative strengths of these things?

140 MR. SIMS:

Yes.

141 MR. HARMON:

And sometimes you can't?

142 MR. SIMS:

That's correct.

143 MR. HARMON:

And would that same general provision apply whether it is RFLP or PCR?

144 MR. SIMS:

Yes.

145 MR. HARMON:

Why don't you remove the strip covering the results for 31.

146 (Witness complies.)
147 MR. HARMON:

As well as the "not excluded" category.

148 (Witness complies.)
149 MR. HARMON:

So would you describe--you have listed in the "not excluded" category the Defendant in this case. Why did you include him in what you saw in the mixture as a result that you saw from item no. 31, the center console?

150 MR. SIMS:

We included the Defendant because his types are present in the sample, 1.1, 1.2 for the DQ-Alpha and also 24, 25 for the D1S80.

151 MR. HARMON:

Okay. And the weaker 1.3, 4, who is that consistent with?

152 MR. SIMS:

That is consistent with Ronald Goldman.

153 MR. HARMON:

Okay. And let's talk about Mr. Goldman's D1S80 type and Renee Montgomery will be testifying next and demonstrating some of these results.

154 MR. SCHECK:

Objection.

155 THE COURT:

Sustained. The jury is to disregard that last comment.

156 MR. HARMON:

Sorry.

157 MR. HARMON:

Umm, how can you sort out, from looking at the reference types of Mr. Simpson, the Defendant, and Mr. Goldman, it appears they have something in common with D1S80; is that correct?

158 MR. SIMS:

Yes, they do. They both share the 24 allele.

159 MR. HARMON:

Okay. So how can you determine that if you see a 24, 25, as you did in this case, is there anything about the results that help you sort out the mixture?

160 MR. SIMS:

In some cases there are. There are clear distinctions. It varies from sample to sample, however.

161 MR. HARMON:

Okay. So let me make sure I understand or we have explained this--you have explained this to the jury. The results from 31, are they are clearly a mixture?

162 MR. SIMS:

Yes.

163 MR. HARMON:

And they are clearly a mixture that is consistent in the stronger regard on DQ-Alpha with the Defendant?

164 MR. SIMS:

Yes.

165 MR. HARMON:

And then the weaker 1.3, 1.4 (sic), could that have come from the Defendant in this case?

166 MR. SIMS:

The weaker 1.3, 4 could not have come from the Defendant.

167 MR. HARMON:

And it is consistent with Mr. Goldman?

168 MR. SIMS:

Yes, it is.

169 MR. HARMON:

Let's just stop for a second and talk about inheriting patterns from parents. Is this mixtures stain--could this mixture stain that we are talking about, item 31, be consistent with an offspring of the Defendant and Nicole Brown?

170 MR. SIMS:

No, not--if you look at, for example, the DQ-Alpha types for the Defendant and also for Nicole Brown, their children would be either 1.1, 1.1 and looking up here now, (Indicating), or 1.1, 1.2.

171 MR. HARMON:

And that is because an offspring would have to inherit a 1.1 from Nicole?

172 MR. SIMS:

Yes.

173 MR. HARMON:

And would have to inherit either a 1.1 or a 1.2 from the Defendant?

174 MR. SIMS:

Yes.

175 MR. HARMON:

That is just DQ-Alpha?

176 MR. SIMS:

Yes.

177 MR. HARMON:

And now D1S80?

178 MR. SIMS:

With regard--

179 MR. HARMON:

What combination of types could an offspring have of the Defendant and Miss Brown?

180 MR. SIMS:

Well, again with the idea that one comes from the mother and one from the father, the D1S80 types for the offspring of Nicole Brown and the Defendant would be 18, 24 or 18, 25.

181 MR. HARMON:

Okay. So the D1S80 type alone that you obtain from item 31, the console, that alone could not be from an offspring of the Defendant, Mr. Simpson, and Nicole Brown?

182 MR. SIMS:

That's correct.

183 MR. HARMON:

And the DQ-Alpha mixture alone could not be consistent with an offspring of the same two people?

184 MR. SIMS:

That's correct.

185 MR. HARMON:

Okay. Let's move to item no. 34, the driver's sidewall in the photograph--

186 MR. SIMS:

Yes.

187 MR. HARMON:

--down at the lower left-hand column, your no. 20. What sorts of tests did you perform on that stain?

188 MR. SIMS:

That was just DQ-Alpha typing.

189 MR. HARMON:

And what results did you obtain?

190 MR. SIMS:

The type was 1.1, 1.2 for no. 34.

191 MR. HARMON:

Okay. Would you remove the covers from that one.

192 (Witness complies.)
193 MR. HARMON:

And the possible or the not excluded, who did you not exclude?

194 MR. SIMS:

Mr. Simpson, the Defendant.

195 MR. HARMON:

And so that result is consistent with him?

196 MR. SIMS:

That's correct.

197 MR. HARMON:

He is a possible source?

198 MR. SIMS:

That's correct.

199 MR. HARMON:

Now, that is the same result that you obtained on item 24, the instrument panel; is that right?

200 MR. SIMS:

Yes.

201 MR. HARMON:

Now, why didn't you do any more tests on those two items?

202 MR. SIMS:

As I recall, there was very limited DNA in those samples.

203 MR. HARMON:

Okay. And taken at face value, given your--what you just told us about the hereditary nature of those samples, that result could be consistent with an offspring of the Defendant, Mr. Simpson, and Nicole Brown?

204 MR. SIMS:

Yes.

205 MR. HARMON:

Let's move on to item no. 293, the carpet on the driver's side. This is in the photo at the bottom in the middle with the pointer.

206 MR. SIMS:

Okay.

207 MR. HARMON:

What sort of tests did you perform on that sample?

208 MR. SIMS:

We performed DQ-Alpha and D1S80 tests.

209 MR. HARMON:

And what were the results of those tests?

210 MR. SIMS:

The results were as follows: For DQ-Alpha the type was a 1.1, 1.1. We noted that there was a possible trace of 1.2 present. For D1S80 the result was 18, 18.

211 MR. HARMON:

Okay. And is that--other than the possible trace that you've described, whom are those results consistent with from among the three reference types in this case?

212 MR. SIMS:

Nicole Brown.

213 MR. HARMON:

Would you remove the cover on those results and the "not excluded" column.

214 (Witness complies.)
215 MR. HARMON:

Could those--we are going to move that up momentarily.

216 (Brief pause.)
217 MR. HARMON:

Do those results, the combination of the DQ-Alpha and the D1S80 types, could those have come from an offspring, a child of the Defendant and Nicole Brown?

218 MR. SIMS:

No.

219 MR. HARMON:

For the same reasons you've described?

220 MR. SIMS:

Yes.

221 MR. HARMON:

What is this possible trace 1.2 in there? What does that mean?

222 MR. SIMS:

Well, when one performs this kind of testing, one can get, especially with these 1 types, what we call these 1 subtypes, one sometimes sees very faint dots and you can't always be sure if those very faint dots are attributable to an actual type or if they may be an artifact from the typing process.

223 MR. HARMON:

So in the context of this case could you say that based on the total of your PCR results, that Mr. Simpson's type could also be in there because he is a 1.1, 1.2?

224 MR. SIMS:

You could not exclude him on that basis if there was some of his DNA present; however, we find no evidence of his DNA in the D1S80 type.

225 MR. HARMON:

And is the D1S80 test, based on your review of the literature and your use of these protocols, is that as equally sensitive--

226 MR. SCHECK:

Objection to this witness--

227 THE COURT:

Sustained, foundation.

228 MR. HARMON:

Okay.

229 MR. HARMON:

Do you feel, based on your observations, your review of the data in this case--I notice we don't have the Defendant's name in that "not excluded" column--are you saying that it is your opinion that he could be included in that stain, based on all the results?

230 MR. SIMS:

I think there is a possibility of that, although not seeing his type on the D1S80, I wouldn't have that information.

231 MR. SCHECK:

Move to strike the last part of the answer.

232 THE COURT:

Overruled.

233 MR. HARMON:

And Mr. Goldman is excluded or not included as the result of these tests; is that correct?

234 MR. SIMS:

We do not find his type so he is excluded.

235 MR. HARMON:

Okay. And item no. 303, the center console stain, which is in the lower right-hand photograph on the board, exhibit no. 172, what sorts of tests did you perform on item 303?

236 MR. SIMS:

We performed DQ-Alpha and D1S80 tests on that sample.

237 MR. HARMON:

And what were the results of those tests?

238 MR. SIMS:

The results were as follows: For the DQ-Alpha, 1--DQ-Alpha 1.1 allele was present, possible 1.2 allele present. 1.3 and 4 alleles were also present, indicating a mixture.

239 MR. HARMON:

Would you remove that under "PCR results."

240 MR. SIMS:

Would you like me to state the--

241 MR. HARMON:

And the D1S80. Sure. I'm sorry.

242 MR. SIMS:

The D1S80 results were mainly the 24 and 25 alleles along with a weaker 18 allele, again indicating a mixture.

243 MR. HARMON:

Okay. So clearly it is a mixture?

244 MR. SIMS:

Yes.

245 MR. HARMON:

Would you remove their cover from the PCR results.

246 (Witness complies.)
247 MR. HARMON:

From among the three reference samples that were provided to you in this case, whom could you not exclude?

248 MR. SIMS:

All--all three of the individuals, the three principals, the two victims and the Defendant, are consistent with being part of that mixture.

KEY QUOTE
249 MR. HARMON:

Could you remove the cover from the "not excluded" column. Does that mean, at least as far as the three reference samples that were provided to you in this case, that the Defendant, Mr. Goldman, and Ms. Brown, were--are possible sources of the stain on 303?

250 MR. SIMS:

Yes.

251 MR. HARMON:

Is there anything about--just focusing on DQ-Alpha, the relative intensity of the DQ-Alpha results--that help you sort out the relative strengths of this things?

252 MR. SIMS:

No. On this particular sample with the DQ-Alpha, the intensities were all very similar.

253 MR. HARMON:

So this is one where the relative intensities don't help you?

254 MR. SIMS:

That's correct.

255 MR. HARMON:

Unlike the glove RFLP results?

256 MR. SIMS:

Yes.

257 MR. HARMON:

And unlike 29, the steering wheel?

258 MR. SIMS:

Yes.

259 MR. HARMON:

Umm, now you are not saying they are the only three people who could have contributed that mixture, are you?

260 MR. SIMS:

That's correct, I'm not saying that.

261 MR. HARMON:

And without knowing the starting line-up of the San Antonio Spurs, you can't exclude them as being the possible contributors of that?

262 MR. SCHECK:

Move to strike that and I take a strong exception to naming certain basketball teams--

KEY QUOTE
263 THE COURT:

Speaking--

264 MR. SCHECK:

--and not others.

265 MR. HARMON:

I will get to the Knicks next.

266 THE COURT:

Proceed.

267 MR. HARMON:

Can he answer that, your Honor?

268 THE COURT:

Proceed.

269 MR. HARMON:

Could you answer that?

270 MR. SIMS:

Yes. I could not exclude the San Antonio spurs.

KEY QUOTE
271 MR. HARMON:

Okay. Just the starting line-up?

272 MR. SIMS:

The starting line-up.

273 MR. HARMON:

Okay. Let's move to 304, the center console stain, your no. 53.

274 MR. SIMS:

Yes.

275 MR. HARMON:

What sorts of tests did you perform on those stains?

276 MR. SIMS:

Again it was DQ-Alpha and D1S80 typing.

277 MR. HARMON:

And what results did you obtain?

278 MR. SIMS:

The results are--to make it simple, the results were the same for three--I'm sorry, for 52 and 53, gave the same results with DQ-Alpha and D1S80.

279 MR. HARMON:

So could you remove that cover from that column.

280 (Witness complies.)
281 MR. HARMON:

And the same as far as possible sources?

282 MR. SIMS:

Yes.

283 MR. HARMON:

Okay. Why don't you remove that.

284 (Witness complies.)
285 MR. HARMON:

And would you characterize them the same? In other words, you cannot exclude the three people that are listed in the "not excluded" column as possible sources of that mixture?

286 MR. SIMS:

That's correct.

287 MR. HARMON:

Let me ask you just a general question about 303 and 304. When you say it is a mixture, are you saying that the types that you see in 303 and 304 in total are more than you would expect to see from a drop of blood from the Defendant in this case?

288 MR. SIMS:

Yes.

289 MR. HARMON:

He could not be the sole source of stain 303 and 304?

290 MR. SIMS:

That's correct.

291 MR. HARMON:

And you can't tell us, for example, if these things were--these different mixtures were deposited on top of one another at different times?

292 MR. SIMS:

I couldn't tell that.

293 MR. HARMON:

You can just tell us what was there at the time you tested it?

294 MR. SIMS:

That's correct.

295 MR. HARMON:

Okay. Let's move to 305, the center console, which again is in that photo in the lower right-hand corner. What test did you submit stain 305 to?

296 MR. SIMS:

That was the DQ-Alpha typing and also the D1S80 typing.

297 MR. HARMON:

What results did you obtain?

298 MR. SIMS:

For that particular sample 305 the DQ-Alpha was 1.1, possible 1.2 and then weaker 1.3 and 4 alleles, indicating again a mixture.

299 MR. HARMON:

And then how about D1S80?

300 MR. SIMS:

D1S80, mainly 24 and 25 alleles with weaker 18 allele, again indicating a mixture.

301 MR. HARMON:

Okay. Now, would you--why don't you remove the covers from that.

302 (Witness complies.)
303 MR. HARMON:

Now, how would you compare--it looks like you have described 305 somewhat differently than 303 and 304; is that true?

304 MR. SIMS:

Yes.

305 MR. HARMON:

And what can you tell us about why you've described them differently?

306 MR. SIMS:

They were--they were described differently because in this particular case with 305 one now sees that the 1.3 and the 4 alleles are weaker than the 1.1 and the possible 1.2.

307 MR. HARMON:

Okay. And you have already described that Mr. Goldman's type, DQ-Alpha type, is 1.3, 4; is that true?

308 MR. SIMS:

That's correct.

309 MR. HARMON:

And when--is this somewhat like the RFLP mixtures, when you can see things stronger and thing weaker than others, that helps you pair types up?

310 MR. SCHECK:

Objection, leading and no foundation.

311 MR. SIMS:

Yes.

312 THE COURT:

Sustained. Rephrase the question.

313 MR. HARMON:

Does it help you pair types up in the DQ-Alpha marker when you see some dots stronger than others?

314 MR. SIMS:

Yes.

315 MR. HARMON:

Okay. And is that the basis for your describing 1.3, 4 as weaker?

316 MR. SIMS:

Yes.

317 MR. HARMON:

Okay. And is it fair--would it be fair to say that 303, 304 and 305 produced consistent results between and among one another?

318 MR. SIMS:

Yes. Overall they are consistent, those three.

319 MR. HARMON:

Is there anything inconsistent between or among any of those three stains?

320 MR. SCHECK:

Objection, vague.

321 THE COURT:

Overruled.

322 MR. SIMS:

No. There is nothing inconsistent other than the weaker 1.3, 4 on 305, but otherwise they are very similar patterns.

323 MR. HARMON:

Would this be a good break time, Judge?

324 THE COURT:

Yes. All right. Ladies and gentlemen, I'm going to take our break for the morning session. Please remember all my admonitions to you. Don't discuss the case--don't discuss the case among yourselves, don't form any opinions about the case, don't allow anybody to communicate with you, don't conduct any deliberations until the matter has been submitted to you. We will stand in recess for fifteen. And let me see counsel for both sides, please.

Key Quotes (4)

Gary Sims
I don't think it is proper for me to stand here and say, oh, yes, that 4 came from Mr. Goldman. That is not the kind of point I'm trying to make at all. The point I want to make is that when you are talking about absolute exclusions we said that we could not make a clear-cut exclusion of Mr. Goldman on that sample. I'm not suggesting for one moment that he is the source of that 4.
Sims draws a careful line between exclusion and inclusion, modeling scientific restraint in front of the jury on a key mixture sample from the Bronco steering wheel.
Gary Sims
All three of the individuals, the three principals, the two victims and the Defendant, are consistent with being part of that mixture.
Direct statement that items 303/304 from the Bronco center console contain DNA consistent with Simpson, Goldman, and Nicole Brown simultaneously.
Gary Sims
Yes. I could not exclude the San Antonio Spurs.
Comic moment punctuating Harmon's point that without individual reference types, no one can be excluded from a mixture — the witness plays along.
Barry Scheck
Move to strike that and I take a strong exception to naming certain basketball teams and not others.
Scheck's objection itself becomes the joke; his follow-up complaint that the Spurs were named but not others draws a laugh and Harmon's quip about getting to the Knicks.

Notable Exchanges (4)

Rockne HarmonGary Sims
Harmon asks whether Sims can exclude the entire starting line-up of the L.A. Lakers without knowing their types; Sims replies he could not exclude them based on numbers alone but could if he had their types. Later the San Antonio Spurs are named explicitly and Sims deadpans he cannot exclude them either.
light
Rockne HarmonGary Sims
Extended exchange on item 29 (steering wheel) where Sims explains at length why he won't call the weak 4 allele Goldman's contribution, insisting it would be 'very prejudicial' to suggest inclusion while also declining to make a clear exclusion — an unusually candid framing from a prosecution witness.
revealing
Rockne HarmonGary Sims
Harmon asks whether the DNA in item 293 (driver's carpet) is consistent with an offspring of Simpson and Nicole Brown; Sims walks through both DQ-Alpha and D1S80 inheritance and concludes it cannot be from their child — effectively pinning the blood to Nicole Brown herself.
strategic

Scheck objects to Harmon naming the San Antonio Spurs 'and not others'; Harmon replies 'I will get to the Knicks next'; Ito simply says 'Proceed.'
