Cross-examination of Dr. Fredric Rieders (part 3)

Witness: Dr. Fredric Rieders
Examiner: Marcia Clark
Called by: Defense • Date: Monday, August 14, 1995 • Utterances: 285
Marcia Clark cross-examines defense EDTA expert Dr. Fredric Rieders on two main fronts: first, his last-minute phone call to competing expert Dr. Henion three days before testimony to discuss (and apparently pressure) Henion's findings in the analogous Sconce poisoning case; second, a significant internal inconsistency between Rieders' written July 17 report (which documented only one parent and one daughter ion for the EDTA identification) and his direct testimony weeks earlier (where he claimed to have seen the full daughter spectrum). Clark also establishes that Rieders never personally operated the testing equipment and only interpreted Agent Martz's charts.
1 (The following proceedings were held in open court:)
2 THE COURT:

Proceed.

3 MS. CLARK:

All right. Back in 1991 then you wrote--may I ask you, sir, did you write a letter to the District Attorney to explain to him what you explained to us, the reason for the discrepancy in yours and Dr. Henion's findings?

4 DR. RIEDERS:

I don't recall that I did. I don't think so.

5 MS. CLARK:

Then did you write any letter to Dr. Lovell back in 1991 to explain that there was a valid acceptable scientific reason for the discrepancy in your results?

6 DR. RIEDERS:

I don't recall that I did.

7 THE COURT:

Hold on. Doctor, would you pull the microphone around, please.

8 (Witness complies.)
9 MS. CLARK:

Did you contact Dr. Henion to discuss with him the discrepancy in your results back him in 1991?

10 DR. RIEDERS:

1991? No, I did not.

11 MS. CLARK:

Did you write him a letter back in 1991 to ask him to discuss with you the discrepancies in your results?

12 DR. RIEDERS:

No. I think we were both on a program at a Pittsburgh conference subsequently and talked about it a little bit then, but that is the only time I think, other than very recently, that I talked to Jack Henion.

13 MS. CLARK:

Now, you knew that you were to return to complete--when was that Pittsburgh conference, sir?

14 DR. RIEDERS:

I think `92. I'm not sure. We were both on the same program.

15 MS. CLARK:

Did you have any knowledge of the status of the Sconce case back in 1991?

16 MR. BLASIER:

Objection.

17 THE COURT:

Sustained.

18 MS. CLARK:

Okay. All right. You knew you were to return to this court to complete your testimony today, August 14; is that right, sir?

19 DR. RIEDERS:

Yes.

20 MS. CLARK:

And you called Dr. Henion on Friday, August 11th, this past Friday, did you not?

21 DR. RIEDERS:

Yes.

22 MS. CLARK:

And you called him for the purpose of discussing his findings in the Sconce case; isn't that correct?

23 DR. RIEDERS:

No.

24 MS. CLARK:

You called him to discuss what tissue he had tested in the Sconce case; isn't that correct?

25 DR. RIEDERS:

No.

26 MS. CLARK:

You called him to get him to agree that he tested the exhumed tissues and not the autopsy tissues; isn't that correct, sir?

27 DR. RIEDERS:

No.

28 MS. CLARK:

Did you discuss with Dr. Henion on this past Friday, August 11th, what tissues he had tested back in 1991?

29 DR. RIEDERS:

It came up, yes.

30 MS. CLARK:

And that was the first time you had ever called Dr. Henion; isn't that correct?

31 DR. RIEDERS:

Yes.

32 MS. CLARK:

And you tried to get him to say that he had tested exhumed tissue and not the autopsy tissues that you tested; isn't that correct, sir?

33 MR. BLASIER:

Objection. The form of the question is argumentative.

34 THE COURT:

Sustained. Rephrase the question.

35 MS. CLARK:

Did you tell Dr. Henion that you believed he had tested the exhumed tissue and not the 1985 autopsy tissue that you tested?

36 DR. RIEDERS:

I didn't tell him I believed that. I told him that that is what was in his report, which I had in front of me. He didn't have his in front of him.

37 MS. CLARK:

And he disagreed with you, didn't he, Dr. Rieders?

38 DR. RIEDERS:

He argued about it. He said he would have to look it up. That is all I know.

39 MS. CLARK:

Isn't it true, Dr. Rieders, that he told you that his notes and his memory he recalled distinctly that he had tested 1985 autopsy tissues? Didn't he tell you that, sir?

40 DR. RIEDERS:

I don't believe he told me that. He told me he thought he might have tested other tissues and he would check it out from his report, which I have here.

41 MS. CLARK:

You don't recall him telling you that he did in fact test the autopsy tissues?

42 DR. RIEDERS:

He told me he thought he might have and he will check his report.

43 MS. CLARK:

Did you try also--did you also ask him to sign an affidavit to the effect that he tested only the exhumed tissues and not the autopsy tissues?

44 DR. RIEDERS:

No. I asked him to verify what was in his report in an affidavit, current affidavit, and to add to it also, which is in his report, that oleandrin is not a substance which is resistant to degradation by putrefaction, which he agreed. He didn't agree to write an affidavit, but he agreed that it was, as did he in his report.

45 MS. CLARK:

Isn't it true, Dr. Rieders, that he refused to sign the affidavit because it was not true, because he did test tissues taken from the 1985 autopsy?

46 DR. RIEDERS:

Absolutely not. He said he didn't want to have anything to do with you or me or anybody else in this case. He was sick and tired of it. That is what he said.

47 MS. CLARK:

Sir, did he tell you that he had spoken to me?

48 DR. RIEDERS:

He said he had been pestered by the Prosecution from hell to breakfast. I'm quoting him.

KEY QUOTE
49 MS. CLARK:

Is that--all right. Dr. Rieders, you wanted to convince Dr. Henion that he had tested older tissues because if that is not the case, then the explanation you gave to this jury is wrong; isn't that correct?

50 DR. RIEDERS:

May we have one question at a time? I did not try to persuade him anything, and so that the second part really isn't relevant to this.

51 THE COURT:

All right. Let's wind up this area, counsel.

52 MS. CLARK:

Now, back in 1991, sir, you were made aware of the fact that Dr. Henion used the LC mass spectrometer. Do you recall that?

53 DR. RIEDERS:

Sure, yeah.

54 MS. CLARK:

And as a matter of fact, at the preliminary hearing didn't the Defense attorney call you as to whether or not you thought the mass spectrometer could be used to test for oleandrin?

55 DR. RIEDERS:

I don't recall.

56 MR. BLASIER:

Objection, irrelevant.

57 THE COURT:

Sustained. Ask him a contemporaneous question.

58 MS. CLARK:

I'm sorry?

59 THE COURT:

Ask him a contemporaneous question. What is his opinion about whether or not that would have been an useful scientific technique at that time on those samples, whether or not there are any advantages or disadvantages. That is the only relevance to that question.

60 MS. CLARK:

I was just about to get to that.

61 MS. CLARK:

In your opinion, sir, when you were asked at the preliminary hearing about the use of the mass spectrometer to test for oleandrin, would that have been an effective--more effective means of testing for the presence of that poison?

62 MR. BLASIER:

Objection, irrelevant.

63 THE COURT:

Overruled.

64 DR. RIEDERS:

I don't recall that that issue was raised, but had it been raised I would have informed the Court of the fact that the--that I was unaware of any published method for determining oleandrin by gas chromatography, mass spectrometry; that probably a liquid chromatography mass spectrometry method might be more applicable. I am aware of that. I was unaware of any published method. And furthermore, I was unaware of anyone myself, certainly in the postmortem forensic toxicology community, who had such equipment at that time available. It was relatively rare.

65 MS. CLARK:

And so, as a matter of fact, you did not believe that anyone had that equipment at that time?

66 DR. RIEDERS:

No, no, I didn't say that, please. Don't put words in my mouth. I said that in the forensic postmortem toxicology communities, medical examiner's laboratories, Coroner's laboratories, I don't know about the FBI, but my colleagues weren't using LC/ms. The one case where LC/ms was used in a postmortem case, it was done by Hewlett Packard out here for somebody that I knew of, so it wasn't a tool that was generally lying around available to anyone at the time. And also, what I want to emphasize, is that I was unaware--

67 MS. CLARK:

Your Honor, this is nonresponsive.

68 DR. RIEDERS:

--of any published report of an analysis for oleandrin in tissues by either GC/ms or LC/ms.

69 THE COURT:

Next question.

70 DR. RIEDERS:

And so I couldn't say that it could be done.

71 THE COURT:

Next question. Let's wind this up. Let's try the Simpson case sometime today.

72 MS. CLARK:

Dr. Rieders, would you agree that someone who was familiar with the operation of that machine would know how to devise a test or perhaps would know how to devise a test that would be effective for the presence of oleandrin?

73 MR. BLASIER:

Objection, calls for speculation.

74 THE COURT:

Sustained.

75 MS. CLARK:

What effort did you make, sir, after hearing the questioning at the preliminary hearing, or at any time before 1991, to determine whether the ms could be used for the testing of oleandrin?

76 MR. BLASIER:

Objection, irrelevant.

77 THE COURT:

Overruled.

78 DR. RIEDERS:

I asked a couple of my colleagues whether they had anything available that could do the job. None of them did. And that is it.

79 MS. CLARK:

I'm sorry, sir, what did you say?

80 DR. RIEDERS:

I said I asked some of my colleagues whether they had any such method for oleandrin available at the time, LC/ms, and none of them did. That is as far as I went.

81 MS. CLARK:

And what effort did you make to determine whether or not Dr. Henion's method was an effective one, after you learned of his negative result?

82 MR. BLASIER:

Objection, irrelevant.

83 THE COURT:

Sustained.

84 MS. CLARK:

Did you make any effort, sir, to send your tissues, the autopsy from 1985 tissues, to Dr. Henion for testing on the LC/ms to confirm or refute the finding that you had?

85 DR. RIEDERS:

That is what I proposed before the autopsy tissues were--before the exhumation was done. I proposed it first to Harvey Giss when he came up with Henion's name. I knew Henion and I knew of the--by that time I found out that he had methodology available and I offered some of the specimens that I had. I again suggested that I think to Dr.--to Brian Finkle and to Dr. Lovell and they turned that down. They said--I was told on the telephone--

86 THE COURT:

All right, doctor.

87 DR. RIEDERS:

--no.

88 THE COURT:

The question was did you offer any of the tissues?

89 DR. RIEDERS:

I sure did.

90 THE COURT:

All right. Next question.

91 MS. CLARK:

And you say you offered those tissues to the Defense, correct?

92 DR. RIEDERS:

I didn't talk to the Defense. I showed them to the Defense. The Defense attorney, Diamond, came to see me, and I showed him. I had them wrapped tightly, sealed, signed and everything in the deep freeze, yes.

93 THE COURT:

All right. That is--

94 MS. CLARK:

And he rejected them?

95 THE COURT:

Wait. This is the end of this inquiry. It is completely irrelevant at this point. Move on to something else.

96 MS. CLARK:

Dr. Rieders, in this particular case you did not do any testing on any of the evidence; is that correct?

97 DR. RIEDERS:

On what?

98 MS. CLARK:

In this case, in the Simpson case?

99 DR. RIEDERS:

No.

100 MS. CLARK:

Did you do any testing on any of the evidence?

101 DR. RIEDERS:

No, I didn't.

102 MS. CLARK:

You just interpreted the tests that were done by Agent Martz, correct?

103 DR. RIEDERS:

That's correct?

104 DR. RIEDERS:

And those tests were performed on equipment that you have never operated, correct?

105 DR. RIEDERS:

Yes.

106 MS. CLARK:

Now, with respect to the finding on the gate, you indicated that you found the single parent and single daughter ion, correct?

107 MR. BLASIER:

Objection, that misstates the testimony.

108 THE COURT:

Overruled.

109 DR. RIEDERS:

I would have to refresh--I have to see what he had--whether he ran a chromatogram where he ran--whether that is the one where he ran all three or whether it was on the sock and where in my opinion it showed the third daughter ion as well. I don't know whether it was this one or the other one.

110 MS. CLARK:

All right. Let me just ask you this: With respect to the single parent and single daughter ion, would you agree, sir, that there may be other compounds that are not EDTA that may have that single parent and single daughter?

111 DR. RIEDERS:

Possible. I don't know of any.

112 MS. CLARK:

I'm sorry?

113 DR. RIEDERS:

I said it is possible. I don't know of any. I didn't find any either.

114 MS. CLARK:

And isn't that also what you said in the Sconce case?

115 DR. RIEDERS:

Beg your pardon?

116 MS. CLARK:

Isn't that also what you said in the Sconce case?

117 MR. BLASIER:

Objection.

118 THE COURT:

Overruled.

119 DR. RIEDERS:

I don't know what you are talking about.

120 MS. CLARK:

When you were asked whether it could have been another compound besides oleandrin, you said it could be but you don't know what that would be; isn't that right?

121 DR. RIEDERS:

Probably, yeah, that's true.

122 MS. CLARK:

I'm going to show you a copy of the report you prepared in this case. Do you have it with you, sir?

123 DR. RIEDERS:

I don't know that I do. Wait a moment.

124 (Brief pause.)
125 DR. RIEDERS:

No, I don't.

126 MS. CLARK:

Perhaps Mr. Blasier has an extra copy.

127 (Brief pause.)
128 MS. CLARK:

I'm going to mark this as People's 586.

129 THE COURT:

586. Don't we already have this report marked?

130 MR. BLASIER:

I thought we did.

131 MS. CLARK:

I don't think so.

132 THE COURT:

All right. 586.

133 (Peo's 586 for id = Dr. Rieders' report)
134 MS. CLARK:

Let me ask you a couple of questions about this report, sir. You recall that you wrote this report on July 17th, 1995, correct?

135 DR. RIEDERS:

I don't recall the date. May I have a copy to refresh my memory?

136 (Discussion held off the record between Deputy District Attorney and Defense counsel.)
137 THE COURT:

Mrs. Robertson, would you make an extra copy, please.

138 (Brief pause.)
139 THE COURT:

All right.

140 MS. CLARK:

Let me show you the date on the--

141 (Discussion held off the record between the Deputy District Attorneys.)
142 MS. CLARK:

All right. Do you see the date, sir, and the name "Mr. Blasier"?

143 DR. RIEDERS:

Yes.

144 (Discussion held off the record between Deputy District Attorney and Defense counsel.)
145 (Brief pause.)
146 MS. CLARK:

Let me ask you something, Dr. Rieders: You don't have a copy of your own report in this case?

147 DR. RIEDERS:

Not any more. I thought you were going to examine me on the Sconce case today, so I brought the file with me.

148 (Discussion held off the record between the Deputy District Attorneys.)
149 MS. CLARK:

Here is another one. Why don't you look at this.

150 MS. CLARK:

Does that appear to be your letterhead, sir?

151 DR. RIEDERS:

Yes.

152 MS. CLARK:

Does that appear to be the report that you wrote for your findings in this case?

153 DR. RIEDERS:

Yes.

154 MS. CLARK:

Is that dated July 17, 1995?

155 DR. RIEDERS:

Yes.

156 MS. CLARK:

Would that be the date that you wrote the report?

157 DR. RIEDERS:

Yes.

158 MS. CLARK:

Now, that report was an accurate summary of your findings; is that correct, sir?

159 DR. RIEDERS:

Yes.

160 MS. CLARK:

And you received the graphs of the tests done by Mr. Martz you indicated I think back in March of 1995?

161 DR. RIEDERS:

Sounds about right.

162 MS. CLARK:

How many hours did you spend reviewing all those charts, sir?

163 DR. RIEDERS:

Endless hours.

164 MS. CLARK:

Can you tell us how many?

165 DR. RIEDERS:

Well over fifty, I know that.

166 MS. CLARK:

You billed for your time, did you not, sir?

167 DR. RIEDERS:

Some of it.

168 MS. CLARK:

And how much time did you bill for?

169 DR. RIEDERS:

I may have billed a total of fifteen or twenty hours.

170 MS. CLARK:

Out of the more than fifty that you spent?

171 (No audible response.)
172 MS. CLARK:

So you basically donated half your time in this case?

173 MR. BLASIER:

Objection, argumentative.

174 THE COURT:

Overruled.

175 DR. RIEDERS:

No, I didn't donate my time. I used it effectively to learn something and so I didn't charge them for that. All right?

176 MS. CLARK:

So how much did you bill for your work in this case, sir?

177 DR. RIEDERS:

I think the total that we've billed so far may be around--gee, I don't really know. We billed $250.00 an hour for a chargeable forensically active work directed towards it. I think it is under $10,000.

178 MS. CLARK:

You have billed under $10,000?

179 DR. RIEDERS:

I believe so.

180 MS. CLARK:

And how much do you bill for each day you spend in court?

181 DR. RIEDERS:

$2500.

182 MS. CLARK:

And so this is your second day in court, correct?

183 DR. RIEDERS:

In court? Actually I don't know whether it is the second or third day. I haven't billed any of this yet.

184 MS. CLARK:

Do you intend to?

185 DR. RIEDERS:

Of course.

186 MS. CLARK:

So when all is said and done, your billing will have been about, conservatively speaking, 15,000?

187 DR. RIEDERS:

I'm sure it will be more than that.

188 MS. CLARK:

You think it will be around 20?

189 DR. RIEDERS:

I don't know. I don't know. I will bill it by time and my record. That is all I can tell you.

190 MS. CLARK:

All right. So you spent over fifty hours reviewing Agent Martz' chart?

191 DR. RIEDERS:

Yeah.

192 MS. CLARK:

And then you wrote this report on July 17th?

193 DR. RIEDERS:

Yes.

194 MS. CLARK:

Which accurately summarizes the findings--the results of your examinations of those charts and graphs, correct?

195 DR. RIEDERS:

It is my opinion and not findings. He made the findings.

196 MS. CLARK:

Fine--

197 DR. RIEDERS:

He put them in his chart. I reviewed them and came to a conclusion based on those findings, yes.

198 MS. CLARK:

All right. And the report summarizes your opinion of his test results, correct?

199 DR. RIEDERS:

Evaluation and opinion, yes; that's correct.

200 MS. CLARK:

All right. Let's look at what your report says, sir. I'm going to direct your attention, this is the first page of your report, to your opinion of the test results on the back gate stain. Specifically, sir, to roman numeral iii. Your opinion in that paragraph is that you found one daughter ion, correct, and one parent ion and that is in paragraph 2?

201 DR. RIEDERS:

That sounds like--

202 MS. CLARK:

Is that right?

203 DR. RIEDERS:

No. That is not what I found. I described the one daughter ion in paragraph 3 that it corresponds to the daughter ion of the EDTA standard.

204 MS. CLARK:

Right. And then in paragraph 2, just above it?

205 DR. RIEDERS:

Yes.

206 MS. CLARK:

You said you found the one parent ion that corresponds to the EDTA standard, correct?

207 DR. RIEDERS:

No, I didn't say I found anything. I said a mass spectral ion corresponding to the parent ion of the EDTA standard was present in the packet.

208 MS. CLARK:

And that was your opinion concerning the gate stain, correct?

209 DR. RIEDERS:

No. This is a description of facts that were in the packet that I got. This is not--this is not opinion. That is just a description.

210 MS. CLARK:

Is that your opinion, sir?

211 DR. RIEDERS:

It is--

212 MS. CLARK:

Look at the graphs. And this is how you interpreted them, correct?

213 DR. RIEDERS:

It is not only how I interpreted them, but that is also what Roger Martz agreed to, that--with me, that retention time corresponded to the EDTA standard, that the mass spectral parent ion corresponded to the parent ion, n plus one of the standard, and that the one ms/ms ion that he monitored individually, the 160, also corresponded to that of the EDTA standard. These are things that he states in his--in his chromatography and his report.

214 MS. CLARK:

All right. And so this--as to this stain, we have one parent and one daughter, but not the full daughter spectrum, correct?

215 DR. RIEDERS:

It says what it says. They have it in their full daughter spectrum. This doesn't refer to it.

216 MS. CLARK:

Dr. Rieders, this report, paragraphs 2 and 3--

217 DR. RIEDERS:

Right.

218 MS. CLARK:

--does this show one daughter and one parent but not the full daughter spectrum was revealed by the graphs?

219 DR. RIEDERS:

I'm sorry, that is not correct. It is not in the report. I didn't refer to the full daughter spectrum because it was such a mess, but it was still there. I had seen it.

220 MS. CLARK:

Sir, have you reviewed the testimony you gave on direct when you were last in this courtroom?

221 DR. RIEDERS:

Well, I went through the tape, yes.

222 MS. CLARK:

Do you recall testifying that you found the full daughter spectrum on the gate stain?

223 DR. RIEDERS:

I think I testified that in looking at the full daughter spectrum that I recognized all three ions as showing on it visibly.

224 MS. CLARK:

Are you sure of that, sir?

225 DR. RIEDERS:

I thought that is what I did. I don't know whether it was the gate or the sock, remember, I told you that, so I don't know which one it was, but on one of them I said that.

226 MS. CLARK:

On one of them you recall saying that, correct?

227 DR. RIEDERS:

Yeah.

228 MS. CLARK:

Then let's assume for a moment, sir, it was the sock. Okay?

229 DR. RIEDERS:

Okay. So that is the--so that would be no. 2, right.

230 MS. CLARK:

All right. Then no. 2, let's go to page 2, sir, because if according to your testimony you found a full daughter ion--the full daughter spectrum for the sock stain, it should be revealed in your report, correct.

231 MR. BLASIER:

Objection, argumentative?

232 DR. RIEDERS:

No.

233 THE COURT:

Sustained. The answer will stand, though.

234 MS. CLARK:

If your finding--if your opinion of the result on the graphs generated by Agent Martz' testing was that the full daughter spectrum was revealed in the sock taken, would you not include that in your report?

235 DR. RIEDERS:

Not necessarily.

236 MS. CLARK:

Don't you think that is an important finding, Dr. Rieders?

237 DR. RIEDERS:

The fact that I interpreted that as actually showing all three ions, I don't know whether it is important. I don't take myself that importantly. But it is a corroborative finding, yes.

238 MS. CLARK:

Sir, with respect to the determination as to whether or not a compound is indeed one that you've identified to the exclusion of all others--

239 DR. RIEDERS:

Oh.

240 MS. CLARK:

--is it not important--is it not important, sir, to find as many identifying characteristics and review them as you can to substantiate your finding?

241 DR. RIEDERS:

Did you say to the exclusion of all others? I never said that, did I?

242 MS. CLARK:

Did you?

243 DR. RIEDERS:

I certainly did not. It is not--nothing is to the exclusion of all others. That is nonsense. You don't know all others, all the billions of compounds.

244 MS. CLARK:

So you cannot say then that the substance found in the rear gate and the sock is EDTA from a preserved tube to the exclusion of all other compounds?

245 DR. RIEDERS:

To the exclusion of all others? I can say it, but I would be lying.

KEY QUOTE
246 MS. CLARK:

Then you will not say it, will you, sir?

247 DR. RIEDERS:

I'm not going to say that, no, of course not.

248 MS. CLARK:

And looking at your report, sir, if you will, concerning the graphs generated for the analysis of the sock stain--

249 DR. RIEDERS:

Yeah, yeah. What about them?

250 MS. CLARK:

That is paragraph 2, correct?

251 DR. RIEDERS:

What the--

252 MS. CLARK:

Paragraph 2 of your report?

253 DR. RIEDERS:

Yes.

254 MS. CLARK:

In that paragraph you describe seeing one parent and one daughter ion, correct?

255 DR. RIEDERS:

I didn't describe seeing. I described the presence or I state the presence of a retention time, a parent ion and a daughter ion.

256 MS. CLARK:

Okay. Did you not put anywhere in this report that you saw the full daughter spectrum, as you testified on July 24th?

257 DR. RIEDERS:

I have not said anything like that in this report, that's correct.

KEY QUOTE
258 MS. CLARK:

And you filed no addendum to this report to indicate that in fact you had found the full daughter spectrum, not just one daughter ion, correct?

259 MR. BLASIER:

Objection, irrelevant.

260 THE COURT:

Overruled.

261 DR. RIEDERS:

Would you repeat that, please.

262 MS. CLARK:

You filed no correction or addendum to your report to reflect the fact that actually you had found the full daughter spectrum and not just one daughter ion, correct?

263 DR. RIEDERS:

Correct.

264 MS. CLARK:

And you would agree, would you not, sir, that the more characteristics you can find that line up with a certain compounds to identify it, the better it is in terms of confirming your findings? Wouldn't you agree?

265 DR. RIEDERS:

Absolutely.

266 MS. CLARK:

And so the finding of the full daughter spectrum was an important interpretation of the graphs, was it not?

267 MR. BLASIER:

Objection, argumentative.

268 THE COURT:

Overruled.

269 DR. RIEDERS:

It became an important issue, yes.

270 MS. CLARK:

But it was not one that you included in your July 17th report?

271 MR. BLASIER:

Objection, asked and answered.

272 THE COURT:

Overruled.

273 DR. RIEDERS:

Correct.

274 MS. CLARK:

Now, after you wrote your July 17th report, sir, you were informed that Agent Martz tested his own unpreserved blood and got the same single parent and single daughter ion result that he found in the gate and the sock stain, correct?

275 DR. RIEDERS:

Similar, yes.

276 MS. CLARK:

Not the full daughter spectrum, but the single parent and single daughter; isn't that correct?

277 DR. RIEDERS:

Yeah. He never checked the second daughter.

278 MS. CLARK:

Sir, did you observe his testimony?

279 DR. RIEDERS:

Yes.

280 MS. CLARK:

It was his testimony that he did not find the second daughter in his own unpreserved blood; isn't that correct?

281 DR. RIEDERS:

He never looked for it.

282 MS. CLARK:

Sir, did you--

283 DR. RIEDERS:

He said very clearly he didn't run the 132 because he didn't think it was necessary. That is the third daughter ion. So he never looked for it.

284 MS. CLARK:

Sir, isn't it true that he testified not just that he didn't--isn't it true that he testified that his blood, unpreserved blood, gave the same parent and single daughter ion results that were found on the gate and the sock? Wasn't that his testimony, sir?

285 DR. RIEDERS:

I think he said similar, yes.

Key Quotes (4)

Dr. Fredric Rieders
He said he had been pestered by the Prosecution from hell to breakfast. I'm quoting him.
Rieders quotes Dr. Henion's characterization of the prosecution, adding color to the dispute over what Henion told each side and undercutting Clark's version of the phone call.
Dr. Fredric Rieders
To the exclusion of all others? I can say it, but I would be lying.
A devastating admission that he cannot definitively identify the substance as EDTA from a preserved blood tube to the exclusion of all other compounds — a core defense claim.
Dr. Fredric Rieders
I have not said anything like that in this report, that's correct.
Rieders concedes the full daughter spectrum finding — central to his direct testimony — does not appear anywhere in his written report, undermining the reliability of that testimony.
Lance A. Ito
Let's try the Simpson case sometime today.
Judge's frustration with Clark's extended detour into the Sconce case signals the court's impatience with the collateral inquiry, but also reveals how much of this cross had drifted from core Simpson evidence.

Evidence (3)

People's 586
Dr. Rieders' written report dated July 17, 1995, summarizing his evaluation of Agent Martz's EDTA test results on the gate and sock stains
Introduced and used to impeach Rieders' direct testimony about finding the full daughter spectrum
Informal
Agent Martz's chromatography charts and graphs testing gate stain and sock stain for EDTA
Referenced throughout as the underlying data Rieders interpreted
Informal
Agent Martz's test results on his own unpreserved blood showing single parent and single daughter ion
Discussed to suggest EDTA findings on evidence were not unusual or incriminating

Notable Exchanges (3)

Marcia ClarkDr. Fredric Rieders
Clark presses Rieders on his August 11 phone call to Dr. Henion, suggesting he was trying to get Henion to support his explanation for their 1991 discrepancy. Rieders denies it was persuasion, says he was reading from Henion's own report. Clark confronts him with the claim that Henion refused to sign an affidavit because it was untrue; Rieders responds that Henion refused because he was exhausted with the case entirely.
heated
Marcia ClarkDr. Fredric Rieders
Clark methodically compares Rieders' July 17 report (one parent, one daughter ion) against his direct testimony (full daughter spectrum visible), extracting the admission that the full spectrum finding appears nowhere in the report and no addendum was ever filed.
strategic
Marcia ClarkDr. Fredric Rieders
Clark extracts that Rieders spent over 50 hours on the case but billed only 15-20 hours at $250/hour, and charges $2,500 per court day. Clark asks if he 'donated' the rest of his time; Rieders bristles and says he used it to learn.
revealing

Light Moments (3)

Lance A. Ito
Lance A. Ito, visibly impatient with the extended Sconce case detour, says: 'Let's try the Simpson case sometime today.'
Dr. Fredric Rieders
Rieders quotes Dr. Henion's colorful complaint that he had been 'pestered by the Prosecution from hell to breakfast,' delivering it deadpan as a direct quotation.
Dr. Fredric Rieders
Rieders arrives to court without a copy of his own report, having brought the Sconce file instead because he assumed that was the focus of the day.

Credibility Attacks (3)

⚔ Dr. Fredric Rieders
Prior inconsistent statement / omission from written report
Clark establishes that Rieders' July 17 report documents only one parent and one daughter ion for both the gate and sock stains, while his direct testimony claimed the full daughter spectrum was visible. Rieders confirms the full spectrum finding is absent from the report and no correction was ever filed.
⚔ Dr. Fredric Rieders
Bias / improper witness contact
Clark highlights that Rieders called Dr. Henion for the first time ever just three days before returning to testify, implying an attempt to align Henion's recollection with Rieders' explanation for the 1991 discrepancy. Rieders denies persuasion but admits the topic of which tissues Henion tested 'came up.'
⚔ Dr. Fredric Rieders
Limitation of expertise / equipment unfamiliarity
Clark establishes that Rieders performed no independent testing in the Simpson case and has never personally operated the equipment Agent Martz used, positioning him as merely an interpreter of another scientist's charts.

Witness Demeanor

(Witness complies.) — adjusting microphone at judge's direction
(Brief pause.) — while copy of report is located
(No audible response.) — after Clark notes he billed for only half his hours
