Cross-examination of Gary Sims (part 1)

Witness: Gary Sims
Examiner: Barry Scheck
Called by: Prosecution • Date: Wednesday, September 13, 1995 • Utterances: 298
Barry Scheck cross-examines Gary Sims, the DOJ DNA expert, focusing on three main areas: the contested 1.3 dot on Bronco console item 31 (which Dr. Gerdes had criticized), the chain of custody of the Bronco between June 14 and August 26, and the surprisingly small total amount of DNA recovered from the console. Scheck establishes that Sims re-ran tests for a similar 1.3 anomaly on a Bundy blood drop (item 52) but not on item 31, and that Sims admits he did not familiarize himself with the Bronco's chain of custody despite it being central to the integrity of samples 303-305.
1 THE COURT:

All right. Thank you, ladies and gentlemen. Please be seated. All right. Let the record reflect that we have been rejoined by all the members of our jury panel. Mr. Sims, would you resume the witness stand, please. All right. Mr. Harmon has completed his direct examination. And Mr. Scheck, you may commence your cross-examination.

2 MR. SCHECK:

Thank you, your Honor. Good morning, ladies and gentlemen of the jury.

THE JURY: Good morning.

CROSS-EXAMINATION BY MR. SCHECK

3 MR. SCHECK:

Mr. Sims, good to see you.

4 MR. SIMS:

Good to see you.

5 MR. SCHECK:

Let's see if we can--

6 THE COURT:

All right. Are you going to put up again People's 172?

7 MR. SCHECK:

Yes.

8 THE COURT:

All right. Got it?

9 MR. SCHECK:

Mr. Sims, could you join me for a minute, and if we could look, just to clarify some of the facts here, at People's 172 and also the results board, People's 260, to understand precisely what you have done here. Now, first of all, items 30 and 31 are depicted in the upper right-hand corner; is that correct?

10 MR. SIMS:

Yes.

11 MR. SCHECK:

Of the People's 172. And those represent swatches that were made on June 14th?

12 MR. SIMS:

Yes, that is my understanding, but those two stains were collected about June 14th.

13 MR. SCHECK:

On June 14th by Dennis Fung and Andrea Mazzola?

14 MR. SIMS:

I'm not sure who collected them, but the date sounds right to me.

15 MR. SCHECK:

And each picture on this board, 29, that is the steering wheel you told us about, right?

16 MR. SIMS:

Yes.

17 MR. SCHECK:

All right. That is the one with the 1.1, 1.2 and 4, correct?

18 MR. SIMS:

Yes.

19 MR. SCHECK:

And number--the next picture over, 33, another picture of the steering wheel, 29, 33 again, 22, 23, 34, the picture showing 25, 26, 27, all those pictures were of collections made on June 14th, 1994? That is your understanding, correct?

20 MR. SIMS:

That's my understanding, yes.

21 MR. SCHECK:

And 293 is a carpet that was pulled out of the Bronco on June 14th, correct?

22 MR. SIMS:

That is my understanding, the carpet was pulled out on that date.

23 MR. SCHECK:

All right. Now, samples 303, 304 and 305, those are the samples that you combined to do your new RFLP test, right?

24 MR. SIMS:

Yes. 303, 304 and 305.

25 MR. SCHECK:

And they are depicted at the bottom right-hand corner here from the console?

26 MR. SIMS:

Yes.

27 MR. SCHECK:

And those stains were collected on August 26th, right?

28 MR. SIMS:

Yes. My understanding it is about that date.

29 MR. SCHECK:

Okay. Now, the results you got on the Bronco samples that were collected on June 14th are shown in the result board here that is 30 and 31, correct?

30 MR. SIMS:

Yes, I believe those are the ones, although 34 I think and 29 were also--

31 MR. SCHECK:

I'm talking about the console?

32 MR. SIMS:

Console, 30 and 31.

33 MR. SCHECK:

That is my question.

34 MR. SIMS:

Yes.

35 MR. SCHECK:

Right, the console?

36 MR. SIMS:

Yes.

37 MR. SCHECK:

Now, 30 is depicted in the upper right-hand corner from that swatch collected on June 14th, you got a 1.1, 1.2, 24, 25, correct?

38 MR. SIMS:

Yes.

39 MR. SCHECK:

And that is a DNA typing that is consistent just with Mr. Simpson?

40 MR. SIMS:

Yes.

41 MR. SCHECK:

And from that typing there is--you can exclude Ronald Goldman and Nicole Brown Simpson?

42 MR. SIMS:

Yes. None of their DNA shows up in that sample.

43 MR. SCHECK:

Okay. Now, the result from 303, the sample taken on August 26th, right?

44 MR. SIMS:

Yes.

45 MR. SCHECK:

All right. Which is that one on the DQ-Alpha and D1S80, you got results that were consistent with Mr. Simpson, Mr. Goldman and Nicole Brown?

46 MR. SIMS:

That's correct.

47 MR. SCHECK:

And in theory it is your understanding that 30 and 303 were taken from the same area?

48 MR. HARMON:

Objection, calls for speculation, misstates the testimony.

49 THE COURT:

Sustained.

50 MR. SCHECK:

Is it your understanding that 303 and 30 were supposed to be bloodstains in the same area?

51 MR. HARMON:

Objection. That is vague, calls for speculation.

52 THE COURT:

Overruled.

53 MR. SIMS:

I remember we went through all this in May and I think we got down to the issue of what is--what are we talking about when we are saying it is exactly the same area?

54 MR. SCHECK:

I didn't say exactly the same. Same general area?

55 MR. SIMS:

Same general area, yes.

56 MR. SCHECK:

Right. That is what the reports you got indicated?

57 MR. SIMS:

Same general area, yes.

58 MR. SCHECK:

Thank you. Now, 31, okay, that is the second stain from the console from June 14th, right?

59 MR. SIMS:

Yes.

60 MR. SCHECK:

And that is the one that you say has a DNA--a DQ-Alpha profile that is consistent with Mr. Goldman?

61 MR. SIMS:

Yes.

62 MR. SCHECK:

All right. Now--your Honor, I'm--for the sake of--I don't know if it can be seen, so I will try to put it in the middle.

63 (Brief pause.)
64 MR. SCHECK:

Now, Mr. Sims, 31--

65 THE COURT:

All right. I'm sorry, Mr. Scheck, you just put up Defense exhibit--

66 MR. SCHECK:

1309.

67 THE COURT:

Thank you.

68 MR. SCHECK:

31 is the item--30 and 31 are depicted here in Defense 1309; is that right?

69 MR. SIMS:

Yes, the DQ-Alpha strips.

70 MR. SCHECK:

And in the upper left-hand corner we see all the strips that were run that day?

71 MR. SIMS:

Yes.

72 MR. SCHECK:

Now, you recall we discussed this, you and I on cross-examination?

73 MR. SIMS:

Yes.

74 MR. SCHECK:

And my--you would agree when I asked you those questions on cross-examination the issues probably weren't so clear the way I did it that way with dots?

75 MR. SIMS:

I thought it was clear.

76 MR. SCHECK:

Oh, you thought it was clear? I apologize. But when dr. Gerdes testified he made points that were similar to precisely the points I made--was making with you when we visited this issue on cross-examination?

77 MR. HARMON:

Objection, that is vague, no foundation.

78 THE COURT:

It is argumentative. Sustained.

79 MR. HARMON:

Argumentative.

80 MR. SCHECK:

All right.

81 MR. SCHECK:

Now, you stated on direct examination one of the concerns that dr. Gerdes expressed with respect to this 1.3 dot, correct?

82 MR. SIMS:

Yes.

83 MR. SCHECK:

Now, wasn't one of the points that dr. Gerdes made is that there was also evidence of the 1.3 dot appearing on the quality sample 86 and the positive control on the same run?

84 MR. HARMON:

Objection, that is beyond the scope.

85 THE COURT:

Overruled.

86 MR. SIMS:

Yes, he mentioned that in his testimony.

87 MR. SCHECK:

Right. And he took the position that scientifically when your controls are showing 1.3's, that shouldn't be there, it is improper to call a 1.3 that is also faint within a mixture? You remember he made that point?

88 MR. SIMS:

Yes.

89 MR. SCHECK:

And your protocol, as we discussed when I cross-examined you, does say that if the quality control and the positive control fail or show unexpected results, that the procedure is to do it again?

90 MR. SIMS:

That's what we would say, yes. In other words, if they show--I think the key word is whether or not they fail, but in my opinion, they didn't fail.

91 MR. SCHECK:

I understand that, but you did not do this again?

92 MR. SIMS:

That's correct.

93 MR. SCHECK:

However--and this is--

94 THE COURT:

All right. Mr. Scheck, just be careful because this easel--

95 MR. SCHECK:

I understand. I think I've got it.

96 THE COURT:

--has got a limited capacity.

97 MR. SCHECK:

1310.

98 THE COURT:

1310. Thank you.

99 MR. SCHECK:

However, on item 52 on board 1310 there was a--what you in your terminology called a 1.3 trace, correct?

100 MR. HARMON:

Objection. It is beyond the scope, your Honor. These are different samples.

101 THE COURT:

Overruled.

102 MR. SIMS:

Yes, it was called a c minus/trace.

103 MR. SCHECK:

Right. And there is also on one of the quality assurance samples in this run what you called a trace of a 1.3?

104 MR. SIMS:

Yes. I believe that is right, but I would like to quickly check the note sheet for that day.

105 MR. SCHECK:

Well, would you accept my representation that this came from the note sheet? Is that your--

106 MR. SIMS:

That is my recollection.

107 MR. SCHECK:

And that on the positive control it was a hint/trace?

108 MR. SIMS:

Yes. In other words, there was more of a dot showing on this particular positive control than the previous one you showed me.

109 MR. SCHECK:

And that you decided, based on this data, to do it again?

110 MR. SIMS:

That's correct.

111 MR. SCHECK:

And the 1.3 here, item 52 is a Bundy blood drop?

112 MR. SIMS:

Yes, it is.

113 MR. SCHECK:

And if that 1.3 were a real allele, then that would indicate that there was perhaps more than one contributor to the stain you had?

114 MR. HARMON:

Objection, 52 is beyond the scope of direct, your Honor.

115 THE COURT:

Overruled. But let's--

116 MR. SCHECK:

Yes, we are moving through it.

117 THE COURT:

Yes.

118 MR. SIMS:

Yes.

119 MR. SCHECK:

Do you recall that?

120 MR. SIMS:

Yes.

121 MR. SCHECK:

And you did it again?

122 MR. SIMS:

Yes.

123 MR. SCHECK:

And in your notes, even though it is not really visible on this strip, it was recorded very faint trace?

124 MR. SIMS:

Yes, I believe that is correct, but I rehybed it.

125 MR. SCHECK:

And the rehybe indicates that the film was developed for 22 minutes?

126 MR. SIMS:

I believe that's correct, yes.

127 MR. SCHECK:

And your protocol is to develop them between 20 and 30 minutes?

128 MR. SIMS:

Yes.

129 MR. SCHECK:

And would you agree that the amount of time that you develop them may relate to the intensity of the 1.3 dot?

130 MR. SIMS:

Well, beyond--beyond about twenty minutes it was really very little difference in those. It is mainly what happens in the first twenty minutes that is the issue.

131 MR. SCHECK:

Well, you didn't indicate on the sheets how long the original run of item 52 was developed?

132 MR. SIMS:

That's correct. I consulted with Renee Montgomery later on that.

133 MR. SCHECK:

All right. Now, dr.--to finish this up, you recall that dr. Gerdes criticized your results by saying that it was inconsistent to call this 1.3 not real and without further testing to call the 1.3 on sample 31 real?

134 MR. SIMS:

I believe that was his testimony, yes.

135 MR. SCHECK:

Okay. So those are some of the concerns that dr. Gerdes expressed with respect to a full rendition of his concerns with respect to sample 31. Fair statement?

136 MR. SIMS:

I think that covers about everything.

137 MR. SCHECK:

Okay. And just so we are all clear, with respect to the console of the Bronco and the samples that were collected on June 14th, the only evidence of DNA testing that you had with respect to the console is that 1.3, 4 finding that you and dr. Gerdes disagree about on item 31?

138 MR. SIMS:

Yes.

139 MR. SCHECK:

Okay. Now, with respect to the results on 303, 304 and 305, you recall that dr. Gerdes expressed the view that the integrity of the evidence had been compromised by the way in which the Bronco was handled between June 14th and August 26th. Do you recall that?

140 MR. HARMON:

Objection, that misstates the testimony. That is argumentative. That is not what he said. It is beyond the scope of the direct examination.

141 THE COURT:

Overruled. Overruled.

142 MR. SIMS:

I believe I saw that in his testimony, yes.

143 MR. SCHECK:

All right. So you recall that with respect to his opinions about 303, 304 and 305, that was a concern of his?

144 MR. SIMS:

I believe that was a concern, yes.

145 MR. SCHECK:

All right. And do you have some familiarity with the way the Bronco was handled between June 14th and August 26th.

146 MR. HARMON:

Objection, no foundation, calls for speculation.

147 THE COURT:

Sustained.

148 MR. HARMON:

Hearsay.

149 THE COURT:

You can ask him if he took that into consideration.

150 MR. SCHECK:

Mr. Sims, from what you know about the way the chain of custody for the Bronco was handled, between June 14th and August 26th, do you think it was handled appropriately, in your forensic opinion?

151 MR. SIMS:

Well, I don't--I don't know the whole history of how that Bronco was maintained. I don't know the whole history of that. I've heard that there were some--

152 MR. HARMON:

Objection. That calls for hearsay, your Honor.

153 THE COURT:

Overruled.

154 MR. HARMON:

Calls for speculation.

155 THE COURT:

Overruled. It is an expert opinion, counsel.

156 MR. HARMON:

I'm sorry.

157 MR. SCHECK:

Please continue.

158 THE COURT:

Overruled.

159 MR. SIMS:

I've heard that the Defense has raised some issues with regard to that. I don't know the truth of the matter on all these issues, though.

160 MR. HARMON:

Object. That is nonresponsive, move to strike. There is no foundation.

161 THE COURT:

Overruled.

162 MR. SCHECK:

Mr. Sims, you heard dr. Gerdes testify about it?

163 MR. SIMS:

I heard him express concerns. I don't know what his basis for those concerns were, other than the general term "Chain of evidence."

164 MR. SCHECK:

Well, you have no knowledge with respect to whether or not this Bronco was secured for further biological analysis between August 26th and June 14th in a way that would preserve the integrity of the evidence? You have no knowledge of that?

165 MR. SIMS:

Well, I--I know what I see in the newspaper and I know, for example, that I think two weeks ago I called a witness that addressed some of those issues, but that is what my knowledge is.

166 MR. SCHECK:

And you have not familiarized yourself then at all with what the history was of how the Bronco was kept? Is that what you are telling us?

167 MR. HARMON:

Objection. That is argumentative, your Honor.

168 THE COURT:

Sustained. Rephrase the question.

169 MR. SCHECK:

Have you--let me try it this way: Mr. Sims, in your forensic opinion, based on your experience--

170 THE COURT:

All right. Mr. Scheck, is it necessary for him to be down there at this point? Simply because the--we ought to use the microphones when we--

171 MR. SCHECK:

All right. I think it would save time if we keep the boards up.

172 THE COURT:

All right. Go ahead.

173 (Brief pause.)
174 MR. SCHECK:

Mr. Sims, to try to cut to the heart of it quickly, let me--let me ask you to assume that between June 14th and August 26th the Bronco automobile was not--was put into a tow yard, that no records were kept as to who entered or left it between June 14th and August 26th, that unauthorized personnel were in and out of that Bronco automobile, that is non-police personnel, they were in the seats, they were looking around the car. Would you consider that an appropriate way to preserve the integrity of biological evidence?

175 MR. SIMS:

Well, I--I don't think that should be allowed. I don't think one should be allowed to come in and out of a car. I think that should be done by authorized people.

176 MR. SCHECK:

And that records should be kept as to who has access and doesn't have access to the vehicle if you were going to preserve blood evidence for future biological testing?

177 MR. SIMS:

Well, when you put it in the context of records should be kept, I don't know. I mean, for example, there may be, you know, other tow yards that I have been involved with in forensic cases where perhaps just one person has the keys, so there is no record kept of all those things, but that should be controlled. Access should be controlled.

178 MR. SCHECK:

So your answer is yes?

179 MR. SIMS:

Well, with what I added to that, yes.

180 MR. SCHECK:

Now--so basically you have no basis for disagreeing with dr. Gerdes' judgment that the integrity of those samples, 303, 304 and 305, was compromised by the chain of custody procedures used in this case?

181 MR. HARMON:

Objection. It is vague as to what type of integrity, your Honor.

182 THE COURT:

Sustained.

183 MR. SCHECK:

All right. You heard his testimony that he believed as a scientist that the chain of custody for those samples compromised the integrity of future analysis? You recall that?

184 MR. SIMS:

Yes, I heard some of that.

185 MR. SCHECK:

And you are saying to us that you are really not familiar with the details of how--of the chain of custody of the Bronco?

186 MR. SIMS:

That's correct. I'm not familiar with those details.

KEY QUOTE
187 MR. SCHECK:

And you have not endeavored to become more familiar with the exact detail of how it was kept and who was in and out of the car?

188 MR. SIMS:

That's correct.

189 MR. SCHECK:

And therefore you wouldn't want to render an opinion on it because you don't have enough information?

190 MR. HARMON:

Objection, it is vague as to opinion about what.

191 THE COURT:

Overruled.

192 MR. SIMS:

Well, I think I did offer the opinion of what should be done with that kind of evidence as far as securing it, yes.

193 MR. SCHECK:

All right. So your general opinion is that wasn't handled properly, but you don't know the specific detail of how bad it was.

194 MR. HARMON:

Objection, that is argumentative.

195 THE COURT:

It is.

196 MR. SCHECK:

I will move on.

197 MR. SCHECK:

Now, just so we are clear, what you have done since we last visited is that you combined the samples that were found on August 26th, 303, 304 and 305, and you put them together; is that correct?

198 MR. SIMS:

Yes, I've put them together.

199 MR. SCHECK:

Now, altogether, when you did the quantitations on all these stains combined, you came up with 72 nanograms of high-molecular weight DNA?

200 MR. SIMS:

Well, there was actually more than that, I believe, after, but some other tests were run in between, but it is about 72 nanograms.

201 MR. SCHECK:

About 72 nanograms?

202 MR. SIMS:

Yes.

203 MR. SCHECK:

And looking at the results, you believe this to be a mixture?

204 MR. SIMS:

Yes.

205 MR. SCHECK:

And the predominant contribution in the mixture is DNA that you say is consistent with Mr. Simpson?

206 MR. SIMS:

Yes.

207 MR. SCHECK:

And that is something on the order of 3 to 1?

208 MR. SIMS:

Yes. I--I would say it is somewhere 3 to 1, maybe 2 to 1, but that is the right ballpark.

209 MR. SCHECK:

And therefore the amount of DNA on the RFLP tests that is consistent with the profile of Mr. Goldman would be something on the order of 20 nanograms of DNA?

210 MR. SIMS:

Somewhere in that area, yes. That is--that is a reasonable approximation.

211 MR. SCHECK:

And that is why you had to put these probes, keep those probes cooking, so to speak, for fifteen or sixteen days, to try to draw up the amount of DNA because there was comparatively a small amount there?

212 MR. SIMS:

Yes. Technically what is going on is that there is a low amount of DNA on that membrane, that southern blot that we made, which means that there is a low amount of radioactive probe that is binding, and so you have to let the film that is--that is developing, you have to let that film go for a longer period of time. Usually we do these in a couple days, but for this type of sample you have to let it go a week or longer to get those weak bands to show up.

213 MR. SCHECK:

So 20 nanograms of DNA, that is really at the low end of your ability to detect, isn't it?

214 MR. SIMS:

Yes. This is getting of the low end of the ability to detect.

215 MR. SCHECK:

Small amount?

216 MR. SIMS:

Small amount.

217 MR. SCHECK:

Now, if we were to look at--to give us some perspective, one drop of blood contains about 1000 nanograms of high-molecular weight DNA?

218 MR. SIMS:

Yes, about a thousand nanograms or one microgram, yes.

219 MR. SCHECK:

All right. And in fact you have seen estimates in the NRC report and other places that some people put it at between one and 2000?

220 MR. SIMS:

Yes, it is in that area.

221 MR. SCHECK:

Now, if you, based on your quantitations, were to combine the amount of DNA that you got as a whole in 305, 304, 303, the August 26th collections, and for just the purpose of this hypothetical, let's also include the amount of DNA that came out of the swatches from 30 and 31--are you with me?

222 MR. SIMS:

Yes.

223 MR. SCHECK:

--would you not agree that combining all of those together, all that from the console together, the amount of DNA would not exceed a hundred nanograms?

224 MR. SIMS:

Well, it might slightly exceed that, but it is around that ballpark.

225 MR. SCHECK:

Around a hundred nanograms?

226 MR. SIMS:

Around a hundred nanograms.

227 MR. SCHECK:

So that is one/tenth of one drop of blood?

KEY QUOTE
228 MR. SIMS:

Well, you have to remember that with a drop of blood, for example, if you are testing liquid blood, that is not the same as extracting DNA out of a stain's worth of one drop of blood, so there is--you are not quite talking apples--you are somewhat talking apples and oranges there, but in terms of the ballpark you are talking about, you know, maybe getting three/quarters of that DNA out, so you can figure it from that.

229 MR. SCHECK:

All right. So what you are basically saying to us is that maybe if you are just dealing with a pristine drop of blood, you won't get a thousand nanograms, you will get 750?

230 MR. SIMS:

Something like that.

231 MR. SCHECK:

Is that what you just said in English?

232 MR. SIMS:

Yes, that is what I just said.

233 MR. SCHECK:

Okay. And if we were to--I mean no disrespect for that, just summarizing it. And so if you've got about a hundred nanograms of DNA and there is 750 nanograms in a drop of blood, can you give me that fraction quickly? That would be, what, about a seventh?

234 MR. SIMS:

Something like that. Something like that.

235 MR. SCHECK:

Okay. So certainly, just reasoning from the DNA alone, the amount of blood, just looking at the DNA in the console, as you said, is in the area of a hundred nanograms of DNA?

236 MR. SIMS:

Yes.

237 MR. HARMON:

Objection. That assumes it was all collected.

238 THE COURT:

Overruled.

239 MR. SIMS:

Well--

240 THE COURT:

Overruled.

241 MR. SCHECK:

Object to the--

242 THE COURT:

Overruled. Overruled. Overruled.

243 MR. SCHECK:

Okay.

244 MR. SIMS:

May I answer?

245 MR. SCHECK:

You actually overruled that speaking objection.

246 MR. HARMON:

Calls for speculation. Calls for speculation.

247 THE COURT:

I overruled the objection. Ask your question.

248 MR. SCHECK:

Oh, overruled the objection?

249 MR. SIMS:

Can I finish my answer to that?

250 THE COURT:

I'm sorry.

251 MR. SCHECK:

I thought you did.

252 THE COURT:

I meant--sustained is what I meant.

253 MR. SCHECK:

That is what I thought you did.

254 THE COURT:

Here is the problem. The moment I start to think about something else--proceed.

KEY QUOTE
255 MR. SCHECK:

Thank you, your Honor.

256 MR. SCHECK:

Okay. Now, you also were asked some questions on--withdrawn. I will start this way: Now, you don't know anything about the order in which blood was deposited on that console?

257 MR. SIMS:

No, I don't know the order in which the blood was deposited.

258 MR. SCHECK:

Are you familiar with the testimony of dr. Baden in this case that Mr. Simpson told him that he had cut himself on the evening of June 12th, I believe, and that he had gone into the Bronco searching for his cellular phone?

259 MR. HARMON:

Objection, that calls for hearsay and no foundation.

260 MR. SCHECK:

This was testimony.

261 THE COURT:

Overruled. Overruled.

262 MR. SCHECK:

And with a small cut on the side of his finger and had blood within the Bronco? Are you familiar with that testimony.

263 MR. HARMON:

Same objection, calls for hearsay and no foundation.

264 THE COURT:

Overruled.

265 MR. HARMON:

Misstates the testimony as well.

266 THE COURT:

Overruled.

267 MR. SIMS:

No, I really wasn't interested in doctor, is it Baden how you say it, in his testimony. I don't recall that. I don't recall his testimony on that issue.

268 MR. SCHECK:

All right. Just look at it then from the point of view of forensic DNA expertise that you have, ask you to assume that there was an initial deposit of Mr. Simpson's blood on the Bronco from a small cut and I ask you further to assume that a--at a later point in time there was a second deposit, all right? Do you have that hypothetical?

269 MR. SIMS:

Okay.

270 MR. SCHECK:

And if one assumes, for the sake of argument and for the sake of this hypothetical, that the bloodstains of 303, 304, 305, all right, were all present also on June 14th, all right, asking you to assume both of these--there is no question, just for the purpose of this hypothetical--that everything that was on--on August 26th, all right, that was found there, was also present on June 14th, just for the purpose of this hypothetical. Are you with me?

271 MR. SIMS:

Okay. On June 14th versus August 26th. Okay. Those are the two collection times.

272 MR. SCHECK:

Right. But if we assume that on August 26th the finding--the stains there 303, 304, 305, were also present on June 14th, but somehow they were missed, okay--

273 MR. SIMS:

Okay.

274 MR. SCHECK:

--your conclusions with respect to mixtures are not inconsistent with two deposits at two separate times?

275 MR. HARMON:

Objection. That is an improper hypothetical. Misstates the testimony. There is no foundation.

276 THE COURT:

Overruled.

277 MR. SIMS:

Okay. I understand the hypothetical, but now give me the last phrase, please, the question.

278 MR. SCHECK:

In other words, your findings here of mixtures are not inconsistent with a contribution of Mr. Simpson's blood at one point in time and then a subsequent contribution of blood from Mr. Goldman at a subsequent point in time?

279 MR. SIMS:

That's correct.

280 MR. SCHECK:

And in fact, based on all the testing that you did, most of the blood, if we--withdrawn. Most of the DNA that you extracted from that console is consistent with Mr. Simpson?

281 MR. SIMS:

In the sample that we look at he would be consistent with the main contributor of that DNA mix.

282 MR. SCHECK:

Something--when you combine 303, 304 and 305, something on the order of 3 to 1?

283 MR. SIMS:

Yes, that is--again, that is a reasonable figure, something like 3 to 1, maybe 2 to 1.

284 MR. SCHECK:

Now, finally, there--you have continued testing--are you still continuing testing in this case?

285 MR. SIMS:

Well, as I mentioned, there is another autorad that we would--I would like to look at this afternoon, another probe or another one of these autorads that we are developing.

286 MR. SCHECK:

Have you tested item 1, the speck on the door that was first observed by Detective Fuhrman?

287 MR. HARMON:

Objection, that is beyond the scope.

288 THE COURT:

Sustained.

289 MR. SCHECK:

Do you have DNA samples from the handrail? Have you tested that?

290 MR. HARMON:

Objection. It is beyond the scope.

291 THE COURT:

Sustained.

292 MR. SCHECK:

Excuse me for one second.

293 (Discussion held off the record between Defense counsel.)
294 MR. SCHECK:

Your Honor, can we approach the bench for just one minute?

295 THE COURT:

Proceed.

296 MR. SCHECK:

On a scope problem. I don't want to ask the question and--

297 THE COURT:

All right. With the court reporter, please.

298 MR. SCHECK:

Take just a second.

Key Quotes (5)

Gary Sims
I think the key word is whether or not they fail, but in my opinion, they didn't fail.
Sims defends his decision not to re-run the 1.3 dot test on item 31, a distinction Scheck uses to highlight inconsistency with his handling of item 52.
Gary Sims
I don't think one should be allowed to come in and out of a car. I think that should be done by authorized people.
Sims concedes that the Bronco should have been secured — effectively validating the defense's chain of custody argument without knowing the specific facts of the case.
Barry Scheck
So that is one/tenth of one drop of blood?
Scheck frames the total DNA recovered from the Bronco console as a tiny, almost trace amount — undermining the significance of the mixture finding.
Lance A. Ito
Here is the problem. The moment I start to think about something else--proceed.
Ito inadvertently says 'overruled' when he meant 'sustained,' then explains himself — a rare candid moment from the bench.
Gary Sims
That's correct. I'm not familiar with those details.
Sims admits he never investigated the specifics of how the Bronco was stored between the two collection dates, undermining his ability to defend the integrity of samples 303-305.

Notable Exchanges (4)

Barry ScheckGary Sims
Scheck walks Sims through the inconsistency of re-running the 1.3 test for item 52 (Bundy blood drop) but not item 31 (Bronco console), directly invoking Dr. Gerdes' criticism. Sims defends on the grounds that the controls on item 31 did not technically 'fail.'
strategic
Barry ScheckGary Sims
Scheck asks Sims to assume the Bronco was placed in a tow yard with no access records and unauthorized personnel. Sims concedes that access should have been controlled, effectively agreeing with the defense's chain of custody critique — while admitting he never investigated what actually happened.
revealing
Barry ScheckGary Sims
Scheck methodically reduces the total DNA from the Bronco console to roughly one-seventh of a single drop of blood, forcing Sims to confirm that 20 nanograms (the Goldman fraction) is near the detection limit and that fifteen to sixteen days of probe development were required.
strategic
Barry ScheckGary Sims
Scheck presents a hypothetical: OJ cut himself on June 12, bled in the Bronco, and a separate Goldman blood deposit occurred later. Sims confirms that the mixture findings are 'not inconsistent' with two separate deposits at two separate times.

Light Moments (3)

Lance A. Ito
Ito says 'overruled' repeatedly — overruling his own overruling — and then clarifies 'I meant sustained is what I meant. Here is the problem. The moment I start to think about something else--proceed.'
Barry Scheck
Scheck implies his own cross-examination was confusing; Sims disagrees: 'I thought it was clear.' Scheck replies: 'Oh, you thought it was clear? I apologize.'
Barry Scheck
After Sims explains the extraction efficiency nuance, Scheck asks: 'Is that what you just said in English?' and Sims confirms.

Credibility Attacks (2)

⚔ Gary Sims
inconsistent application of protocol
Scheck shows that Sims re-ran the test for item 52 when the positive control showed a 1.3 trace, but did not re-run it for item 31 under similar circumstances — contradicting the DOJ's own protocol requiring a redo when controls show unexpected results.
⚔ Gary Sims
lack of foundation / ignorance of key facts
Scheck establishes that Sims never investigated the chain of custody of the Bronco between June 14 and August 26, and bases his knowledge only on newspaper reports and one recalled witness — undercutting his ability to vouch for the integrity of samples 303-305.
