Cross-examination of Professor Herbert MacDonell (part 3)

Witness: Prof. Herbert MacDonell
Examiner: Marcia Clark
Called by: Defense • Date: Monday, July 31, 1995 • Utterances: 318
Marcia Clark cross-examines defense blood spatter expert Prof. Herbert MacDonell, focusing primarily on a damaging inconsistency: his written report described the sock stain as a 'swipe,' but he testified on direct that it was a 'compression.' Clark also establishes that neither MacDonell's nor Dr. Lee's contemporaneous notes document the 'little balls,' 'voids,' or 'lateral transfer' that formed the core of his direct testimony, and that his report was written entirely from memory three months after the April 2nd examination.
1 MS. CLARK:

All right. These photographs we will stipulate were taken on February 16, 1995.

2 THE COURT:

All right. Is that agreeable to the Defense?

3 MR. NEUFELD:

Yes. On a date when Professor MacDonell wasn't there.

4 THE COURT:

That's correct.

5 MS. CLARK:

So you did not see this manipulation by Dr. Lee, correct?

6 PROF. MACDONELL:

I wasn't there. No, I did not see them.

7 MS. CLARK:

And he didn't do that kind of manipulation again in your presence on April 2nd; is that right?

8 PROF. MACDONELL:

If he did, I didn't see him do it. I don't believe he did.

9 MS. CLARK:

I'm showing you now People's 555. Again, you recognize Dr. Henry Lee?

10 PROF. MACDONELL:

Yes, I do.

11 MS. CLARK:

This is his manipulation of the sock on February 16th, 1995 again?

12 PROF. MACDONELL:

Now, that appears more a manipulation than the first one. The first one, I'd say he was just holding it up, not manipulating it. This one, it appears he is either turning it inside out or at least manipulating it in some fashion.

13 MS. CLARK:

And is that something that you also did on April 2nd, 1995?

14 PROF. MACDONELL:

We turned them inside out, yes.

15 MS. CLARK:

In the manner in which Dr. Lee is doing?

16 PROF. MACDONELL:

Well, in any manner you can to turn socks inside out. I don't think there's much choice. This looks about the only way to do it.

17 MS. CLARK:

All right. Now, showing you People's 556. Does that appear to be a photograph of Dr. Lee taking a picture through a microscope, sir?

18 PROF. MACDONELL:

Yes. He's taking a picture through a stereobinocular microscope using the right ocular.

19 MS. CLARK:

And again, we stipulate this is February 16th, 1995; is that right?

20 PROF. MACDONELL:

I don't know.

21 MS. CLARK:

No. I'm asking counsel.

22 PROF. MACDONELL:

I'm sorry.

23 MR. NEUFELD:

Oh, yes.

24 MS. CLARK:

So it would appear that he did examine the socks under a microscope on that date, correct, sir?

25 PROF. MACDONELL:

Yes. A low-power stereobinocular. I think the maximum magnification is about 25 diameters with most stereobinocular microscope.

26 MS. CLARK:

Now, the microscope that you used on April the 2nd, 1995 had what power magnification?

27 PROF. MACDONELL:

It was 7 to 70.

28 MS. CLARK:

You do not know or do you know for a fact--have you ever seen this microscope up close, sir?

29 PROF. MACDONELL:

Not this particular one, no. I have one, but not exactly the same model.

30 MS. CLARK:

So are you sure when you say that this--the greatest magnification, power on this microscope would be 25 times?

31 PROF. MACDONELL:

No. That's why I said they're usually 7 to 25.

32 MS. CLARK:

Okay. Now, the photograph that you've shown us here--the photograph that you've shown us here of the little ball on the inside of the sock, that was taken on April 2nd when you were present, correct?

33 PROF. MACDONELL:

That's correct.

34 MS. CLARK:

You don't know of any such photographs that were taken on February 16th by Dr. Lee, do you?

35 PROF. MACDONELL:

No, I--

36 MR. NEUFELD:

Objection. No foundation for that question. He didn't even know it was there.

37 THE COURT:

Sustained. Sustained.

38 MS. CLARK:

Have you been shown any photographs taken by Dr. Lee on February 16th showing the little balls on the inside of the sock?

39 PROF. MACDONELL:

No, I have not.

40 MS. CLARK:

And the photograph that you produced here in court showing the little ball on the inside of the sock, the one that you have shown is what magnification?

41 PROF. MACDONELL:

I would approximate the magnification of the actual print to well over 100 diameters, but I have not made that calculation. I do not know the diameter of the first picture that I saw, which is a four by six. And if I don't know how big the magnification is on this, I could ordinarily make it--make the correction. But without knowing a starting point, I can't proportion it up. I'm estimating from memory of what I saw, that that would be about a hundred or more diameters. Dr. Lee could tell you exactly.

42 THE COURT:

All right. Miss Clark, our record is rather sloppy here. You're referring to photographs of red balls. Which exhibit are we talking about here? I think it's 1278 I think. I'm not certain.

43 MS. CLARK:

1278?

44 PROF. MACDONELL:

Yes.

45 MS. CLARK:

Because one is--

46 THE COURT:

You're referring to it, counsel. So you tell us which one you are talking about.

47 MS. CLARK:

1279.

48 PROF. MACDONELL:

It's 1278.

49 MS. CLARK:

That one.

50 THE COURT:

Is that large one 1278, Mr. Gordon?

51 MR. GORDON:

Yes, your Honor.

52 THE COURT:

1278.

53 MS. CLARK:

Is that 1278?

54 MS. CLARK:

Okay. The one we're referring to, sir, is the one with the little ball in the blue circle.

55 PROF. MACDONELL:

Yes.

56 MS. CLARK:

That's 1278.

57 PROF. MACDONELL:

Correct.

58 MS. CLARK:

Okay. You were not shown any such photographs that were taken by Dr. Lee on February 16th, 1995, correct?

59 PROF. MACDONELL:

That's correct.

60 MS. CLARK:

To your knowledge, do any exist?

61 MR. NEUFELD:

Objection.

62 THE COURT:

Sustained. He hasn't seen any.

63 MS. CLARK:

All right, sir. Now, were you aware that on August 4th, the same day the socks were tested, given the presumptive test for blood, the first step of which you saw the sampling of which you saw in the photograph, Susan Brockbank also examined those socks for hair and trace. Were you made aware of that?

64 PROF. MACDONELL:

I believe I read that, yes.

65 MS. CLARK:

Okay. And that has no impact on your opinion as to how those little balls got there?

66 PROF. MACDONELL:

No, it does not.

67 MS. CLARK:

And you were also made aware then that Greg Matheson performed serological testing for PGM subtyping on that sock after August the 4th. Were you made aware of that, sir?

68 MR. NEUFELD:

Objection. It's misleading. May we approach?

69 THE COURT:

Overruled. Rephrase the question though.

70 MS. CLARK:

Greg Matheson performed PGM subtyping on the--that stained area of the sock after August 4th. Were you made aware of that?

71 MR. NEUFELD:

Objection, because he cuts out a portion and removes it.

72 THE COURT:

Yes. Rephrase the question.

73 MS. CLARK:

Were you made aware of the fact, sir, that in order--that to perform PGM subtyping testing, Greg Matheson cut a portion out of the sock in order to perform that testing?

74 PROF. MACDONELL:

Yes.

75 MS. CLARK:

And that he had to handle the sock in the process of doing that?

76 PROF. MACDONELL:

Obviously.

77 MS. CLARK:

And that has no impact on your opinion as to how those little balls got there?

78 PROF. MACDONELL:

No. No, it doesn't.

79 MS. CLARK:

All right. Sir, now you prepared a report in this case; did you not?

80 PROF. MACDONELL:

Yes, I did.

81 MS. CLARK:

And that report is dated July 11th, 1995?

82 PROF. MACDONELL:

I believe it is.

83 MS. CLARK:

You've been working for the Defense since August of `94; is that right?

84 PROF. MACDONELL:

Well, that's when they first contacted me. I actually didn't have anything to do until I'd made a trip to Albany I think in December.

85 MS. CLARK:

And this report is the only one that you have prepared in this case, correct?

86 PROF. MACDONELL:

That's correct.

87 MS. CLARK:

And it details only your observation of the one area of the sock where you saw those little balls, correct?

88 PROF. MACDONELL:

That's correct.

89 MS. CLARK:

You examined both socks, didn't you?

90 PROF. MACDONELL:

Yes, I did.

91 MS. CLARK:

And there's nothing in your report about the other sock; is that right?

92 PROF. MACDONELL:

No, there isn't.

93 MS. CLARK:

Or any of the other stains on the sock that you did observe?

94 PROF. MACDONELL:

That's correct.

95 MS. CLARK:

So it's just--so your report is confined to the one stain that you testified to here in court; is that right?

96 PROF. MACDONELL:

That's correct.

97 MS. CLARK:

Now, if I understand your testimony correctly, sir, the inside of that stain--I'm going to try and number these surfaces, make it easier. The outside portion of the stain where the blood was first received is surface 1, inside, surface 2, the inside of the opposite side, surface 3. Okay? It's your testimony, sir, that the transfer to surface 3 came from surface 2; is that right?

98 PROF. MACDONELL:

Yes. It--if it's transferred from that surface. Again, I did not determine what that material is. The only way it could have gotten there is for a liquid that is red to have gone from surface 2 to surface 3.

99 MS. CLARK:

And now, you've testified that you did not perform any tests on the cut-out area, on that cut-out fabric from the center of the stain to quantify how much blood was in it?

100 PROF. MACDONELL:

That's correct.

101 MS. CLARK:

Now, if the--as a matter of common sense, would it be fair to state, sir, that the more blood you have on the inner aspect of that stain, the more little balls you expect to find on the opposite side?

102 MR. NEUFELD:

Objection. Vague as to "Inner aspect."

103 THE COURT:

Sustained. You just finished numbering the sides. Why don't you--

104 MS. CLARK:

All right. The more blood, the more liquid or blood that you have on the area of surface 2, the inside of the sock, the more little balls you're going to expect to see on surface 3; is that right?

105 PROF. MACDONELL:

As you've said, it would be more likely. It's common sense. Certainly.

106 MS. CLARK:

And of course, this assumes that the little balls on surface 3 can be attributed to the stain on surface 2, correct?

107 PROF. MACDONELL:

Absolutely.

108 MS. CLARK:

And you have not said that you make that assumption; have you not, sir?

109 THE COURT:

You can not say that you haven't said it; have you not?

110 MS. CLARK:

No. See? Clear to me.

111 THE COURT:

All right.

112 MS. CLARK:

You indicated that--I believe in your direct testimony, you've made the statement that if the stain in surface 2 is related to the little balls on surface 3, that they would have gotten there when wet. Do you recall that?

113 PROF. MACDONELL:

Yes.

114 MS. CLARK:

But you can not say that the little balls on surface 3 are related to the stain on surface 2, can you, sir?

115 PROF. MACDONELL:

No, I can't.

116 MS. CLARK:

Now, it would be true, would it not, that the more blood you have on surface 2, the more little balls you expect to find on surface 3?

117 PROF. MACDONELL:

Only if the little balls are blood.

118 MS. CLARK:

If they are.

119 PROF. MACDONELL:

Yes. Certainly.

120 MS. CLARK:

And you found only six or seven; is that right?

121 PROF. MACDONELL:

That's the number of what I would call balls which look like a wet material that dried adhering to fibers, yes. I saw other red spots.

122 MS. CLARK:

Let's just talk about those little balls for a sec. You only brought in a photograph of one of them, correct?

123 THE COURT:

I think we've asked this question now three times, counsel.

124 MS. CLARK:

Why weren't all of them photographed, sir?

125 PROF. MACDONELL:

I have no idea. We photographed the most representative. Dr. Lee, again, took the pictures, and that's a question you'd have to direct to him. I observed them.

126 MS. CLARK:

Now, you made no attempt to quantify the volume of those six or seven little balls, did you?

127 MR. NEUFELD:

Objection.

128 THE COURT:

We've asked that question already.

129 MS. CLARK:

Okay. You indicated that there were also other little flakes?

130 PROF. MACDONELL:

There are many red spots that show up in the photograph that has been introduced that are clearly little red areas. And if the microscope was adjusted in its depth of field, in other words, focused, you would lose the one that we have photographed and then you would see others. So they're clearly evident. There are red areas in there, and those are the areas to which I made reference.

131 MS. CLARK:

But they are not photographed, are they, sir?

132 PROF. MACDONELL:

Yes, but they're out of focus.

133 MS. CLARK:

So you can't see them in the photograph that you took?

134 PROF. MACDONELL:

You can see them, but you can't resolve them.

135 MS. CLARK:

So did you make any attempt to have a photograph taken that would resolve them so the jury could see them?

136 MR. NEUFELD:

Objection. Argumentative.

137 THE COURT:

Sustained. Rephrase the question.

138 MS. CLARK:

Did you make any effort to take a photograph that would have those flakes that you saw in good resolution?

139 MR. NEUFELD:

Objection. He's not talking about flakes.

140 THE COURT:

Overruled.

141 PROF. MACDONELL:

The photograph that's introduced shows the best representation of the drying of a red fluid. Other red spots could be flakes as you just stated. They could have been other of the red balls we saw. I can not tell because they're so far out of focus. They are not resolved.

142 MS. CLARK:

Though these little balls are a very important aspect of your testimony; are they not, sir?

143 MR. NEUFELD:

Objection. Argumentative.

144 THE COURT:

Sustained.

145 MS. CLARK:

All right. Sir, in your terminology, a swipe is different than a compression; is that right?

146 PROF. MACDONELL:

To the extent that one involves lateral motion, the other involves compression. They are both transfer mechanisms.

147 MS. CLARK:

They are both methods of transfer. Is that what you said?

148 PROF. MACDONELL:

I said they're both transfer mechanisms.

149 MS. CLARK:

Nevertheless, are they separate and distinct mechanisms of transfer?

150 PROF. MACDONELL:

Yes. As opposed to other means of staining such as dripping or projection.

151 MS. CLARK:

Well, you took great pains to explain to this jury, did you not, that this was a compression and not a swipe; is that right?

152 MR. NEUFELD:

Objection.

153 THE COURT:

Sustained. Rephrase the question.

154 MS. CLARK:

You went to some length in your testimony, sir, to describe for this jury how this was a compression and not a swipe?

155 MR. NEUFELD:

Objection. Argumentative.

156 THE COURT:

Sustained. Sustained. Rephrase the question.

157 MS. CLARK:

Sir, were you attempting to explain to this jury the difference between a swipe and a compression with regard to your observation of the stain on this sock?

158 PROF. MACDONELL:

Well, I thought I did. I didn't attempt. I thought I explained it clearly enough, the difference, yes.

159 MS. CLARK:

And why did you want to explain to them the difference between a swipe and a compression?

160 PROF. MACDONELL:

So they would know they're both surface. I think I was asked if it was a swipe initially or that came up. So I differentiated between the two. I said I looked to see if there were any trailings or featherings to see if it was a swipe. The difference between the two is really not significant. It's just a matter of my classification.

161 MS. CLARK:

If it's not significant, sir, then why did you draw a distinction before the jury?

162 PROF. MACDONELL:

Because there is a distinction.

163 MS. CLARK:

Then some transfers are swipe and others are compression; is that right, sir?

164 PROF. MACDONELL:

That is correct.

165 MS. CLARK:

And they are distinct in your opinion?

166 PROF. MACDONELL:

They're different. One involves lateral motion. The other does not. That's the extent of the difference.

167 MS. CLARK:

Okay. So a swipe could occur if I move my ankle across a wet surface; is that right?

168 MR. NEUFELD:

Objection. Vague as to the "Wet surface."

169 THE COURT:

Sustained.

170 MS. CLARK:

A swipe could occur if I move my ankle against a wet wound?

171 PROF. MACDONELL:

Certainly.

172 MS. CLARK:

Now, your report, sir, is an accurate summary of your findings with respect to the sock a; is it not?

173 PROF. MACDONELL:

I believe so, yes.

174 MS. CLARK:

And you took pains to make sure that it accurately reflected your findings in this case; did you not?

175 MR. NEUFELD:

Objection as to "Pains."

176 THE COURT:

Overruled.

177 PROF. MACDONELL:

I prepared it as accurately as I could at the time. I have no reason to suspect there's any error.

178 MS. CLARK:

And you signed the report; did you not?

179 PROF. MACDONELL:

Yes.

180 MS. CLARK:

And you reviewed the report before signing it I take it?

181 PROF. MACDONELL:

I usually do.

182 MS. CLARK:

And you examined that report before you testified; did you not?

183 PROF. MACDONELL:

Not recently. I did it I think two trips ago.

184 MS. CLARK:

You prepared that report, sir, based on your observations of April the 2nd, 1995; is that right?

185 PROF. MACDONELL:

That's correct.

186 MS. CLARK:

And in that report, you documented what your observations were?

187 PROF. MACDONELL:

To some extent, yes.

188 MS. CLARK:

But it was an accurate summary; was it not?

189 PROF. MACDONELL:

I believe it to be.

190 MS. CLARK:

Do you have a copy of your report here, sir?

191 PROF. MACDONELL:

Yes, I do.

192 MS. CLARK:

Would you mind getting it out, please?

193 MS. CLARK:

Too much stuff.

194 MR. NEUFELD:

One moment, please.

195 (Brief pause.)
196 THE COURT:

All right. Proceed.

197 MS. CLARK:

Thank you.

198 MS. CLARK:

Sir, let me direct your attention to paragraph 4. Did you not write in this report, sir, when the sock is laid flat, the stain described in .2 is directly below the stained area described in .1, the only reasonable conclusion therefore is that the fluid that caused these stains was swiped against the outside of the left side of the sock? That is what you wrote in your report; is it not?

199 PROF. MACDONELL:

That is correct.

200 MS. CLARK:

And you considered that to be an accurate depiction of what you observed on April the 2nd, 1995; is that correct?

201 PROF. MACDONELL:

That's what I wrote, yes.

202 MS. CLARK:

That's what you wrote. And yet, you testified to the fact that you now believe that to be a compression and not a swipe. Wasn't that your testimony, sir?

203 PROF. MACDONELL:

That was my testimony.

204 MS. CLARK:

Now, sir, wouldn't you agree that with respect to the differentiation that you have made, the distinctions that you have indicated you made between swiped and compression, that was an important distinction; was it not?

205 PROF. MACDONELL:

That's not important at all. As I said, swiping shows there is a lateral component to a compression. They're both transfer mechanisms. Compression occurs in swiping. And I wrote "Swiping" here. It does not matter whether it said compression or swiping. This pushing of blood or any flood into a fabric is a compression.

206 MS. CLARK:

And yet--

207 PROF. MACDONELL:

Swiping merely means there's lateral movement accompanying it. When I looked at it here, it appeared to be swiping. I have since seen enlarged photographs that we took that show that the swiping appearance which is on the surface of the fibers seems to be fairly uniform on both sides. So now I would say it's more likely a compression only. Both are compression. One has lateral movement. I described lateral movement as well.

208 MS. CLARK:

All right. Did you take any notes at the time that you made your observations of this sock to document what you saw?

209 PROF. MACDONELL:

Yes. Very--very few. Dr. Lee was describe.

210 MS. CLARK:

You personally took notes, sir?

211 PROF. MACDONELL:

Yes. Very--

212 MS. CLARK:

Did you turn them over to the Defense?

213 PROF. MACDONELL:

Yes.

214 MR. NEUFELD:

They have been turned over to the Prosecution, your Honor.

215 MS. CLARK:

No, they have not.

216 THE COURT:

All right. We'll take this up later. Proceed.

217 MS. CLARK:

May I see those notes, sir?

218 (The witness complies.)
219 MS. CLARK:

Thank you.

220 PROF. MACDONELL:

You're welcome.

221 MS. CLARK:

Tell me where in those notes, sir, you indicate that there was no lateral movement in the stain that you characterized in your report as a swipe?

222 PROF. MACDONELL:

I don't characterize it either way.

223 MS. CLARK:

And tell me where in your report you demonstrate or you document your observation that there was no lateral movement.

224 PROF. MACDONELL:

I don't believe I did.

225 MS. CLARK:

And tell us where in your report you document the observation of voids that you've testified to here in court.

226 PROF. MACDONELL:

I don't believe I did that either.

227 MS. CLARK:

Now, the lack of lateral movement and the appearance of voids were the indicia that you testified to as evidence that this was a compression and not a swipe. Isn't that your testimony?

228 PROF. MACDONELL:

That's correct. And when I indicate voids for descriptive purposes, that's one thing. But I don't have to indicate them to know what I'm seeing. So I know what the meaning of the term is. And that's why I wouldn't bother to put there are voids here, there are voids there. That is part of seeing a compression transfer or a lateral transfer.

229 MS. CLARK:

But you did not put down "Compression transfer" in your report, did you, sir?

230 PROF. MACDONELL:

No. It was written for attorneys. Not scientists.

KEY QUOTE
231 MS. CLARK:

Sir, you are aware of the fact that counsel has retained you as an expert; isn't that right?

232 PROF. MACDONELL:

I hope so.

233 MS. CLARK:

And you are aware of the fact that the report that you give to them is turned over to the People as well before you testify?

234 PROF. MACDONELL:

Certainly it is.

235 MS. CLARK:

You filed no addendum to your report to reflect the change from swipe to compression, did you?

236 PROF. MACDONELL:

There's no change. They're both transfers.

KEY QUOTE
237 MS. CLARK:

They are both transfers, but you made a distinction, you made a point of telling us it was a compression and not a swipe; isn't that right?

238 PROF. MACDONELL:

That is the way it appeared at the examination. The photographs I examined later showed it to be more uniform, and, therefore, I concluded it was more likely simply a compression. It could still be a swipe.

239 MS. CLARK:

And you filed no addendum to indicate to the People that you were going to change from a swipe that you indicated in your report to a compression that you testified to here in court; isn't that right?

240 MR. NEUFELD:

Objection. Argumentative.

241 THE COURT:

Sustained. Rephrase the question.

242 MS. CLARK:

What effort did you make, sir, to inform the People of the fact that you weren't sure if it was a swipe or a compression, but you were leaning towards compression?

243 MR. NEUFELD:

Objection. Irrelevant as to what is assumed by the People.

244 THE COURT:

Sustained.

245 MS. CLARK:

Sir, knowing that your report said a swipe and said nothing about a compression, wouldn't you agree it was very misleading not to make an effort to inform--

246 THE COURT:

Sustained. Argumentative, counsel.

247 MS. CLARK:

You did not write any new report to indicate that you were uncertain as to whether it was a swipe or that you had changed your mind to say now that it was a compression?

248 PROF. MACDONELL:

From July 11th, I haven't had time to read my initial report. I've been traveling. I have not made any addendum, no. There's no correction to be made.

249 MS. CLARK:

No correction to be made because it still could be a swipe. Is that your testimony?

250 PROF. MACDONELL:

It's a matter of interpretation. If you agree that the fine blood on the surface of the fibers is uniform on each side of that elliptical stain, then it's more likely compression. It's a compression mechanism. If it's a swipe, it could be that the leading edge and the trailing edge are basically the same geometry. It's a distinction that is really in my mind totally irrelevant.

251 MS. CLARK:

So to you, it makes no difference whether you call it a swipe or compression. Is that your testimony, sir?

252 PROF. MACDONELL:

A swipe is a compression with lateral motion.

253 MS. CLARK:

Do you recall how many times in your testimony on direct examination you said that this was a compression and not a swipe?

254 PROF. MACDONELL:

I may have said it several times. I have no idea how many.

255 MS. CLARK:

And if that is the case, sir, that you said it several times, what would be the point of that if it were unimportant to distinguish between the two?

256 MR. NEUFELD:

Objection. Argumentative.

257 THE COURT:

Sustained.

258 MS. CLARK:

If it makes no difference, sir, then why testify before this jury repeatedly that it was a compression and not a swipe if it doesn't matter?

KEY QUOTE
259 MR. NEUFELD:

Objection. Argumentative.

260 THE COURT:

Overruled.

261 PROF. MACDONELL:

So they would be reminded and understand it.

262 MS. CLARK:

But you didn't make any effort to tell this jury that it didn't matter whether you call it a swipe or a compression until just now; isn't that right, sir?

263 MR. NEUFELD:

Objection. Argumentative.

264 THE COURT:

Sustained.

265 MS. CLARK:

You did not tell the jury before cross-examination that it didn't matter whether it was a swipe or a compression, did you, sir?

266 PROF. MACDONELL:

No, I did not.

267 MR. NEUFELD:

Objection.

268 THE COURT:

Overruled.

269 MS. CLARK:

Now, is it--now, the notes that you have before you that were taken--made contemporaneously with the observations on April the 2nd, contain no description of little balls, do they?

270 PROF. MACDONELL:

No. Again, I was not describe. I made a couple of very simple sketches and Dr. Lee made all the tests and made all the detailed notes.

KEY QUOTE
271 MS. CLARK:

And can you tell us, sir, if you have his notes with you?

272 PROF. MACDONELL:

I believe I do have his notes.

273 MS. CLARK:

Please look at his notes and tell us whether Dr. Lee makes any--has any description in his notes of little balls, lateral swipe or voids.

274 PROF. MACDONELL:

(The witness complies.) No. He only mentioned that he takes photographs of them.

275 MS. CLARK:

He mentions that there are photographs taken of the holes; isn't that right, sir?

276 PROF. MACDONELL:

Photographs taken, and he indicates little tiny dots within the cut-out area. He states blood-like materials were observed on the inner surface of the other side of this cut, and he's got many little tiny dots, and it says photographs taken, photo micrographs.

277 MS. CLARK:

And where is the description in his notes of lateral transfer--of lateral swipe? Excuse me.

278 PROF. MACDONELL:

He doesn't use those words. He says a reddish brown color around--he shows it around the cut-out area.

279 MS. CLARK:

Uh-huh. There is no note there concerning lateral swipe; isn't that right?

280 PROF. MACDONELL:

Not on this page, no.

281 MS. CLARK:

Nor on any page of his notes?

282 PROF. MACDONELL:

No, not that I recall.

283 MS. CLARK:

Right. And there's no mention in there of voids either, is there?

284 PROF. MACDONELL:

There was mention of voids and lateral transfer or transfer, but not in his report. We discussed it.

285 MS. CLARK:

There was verbal discussion on April the 2nd. Is that what you're saying, sir?

286 PROF. MACDONELL:

There was.

287 MS. CLARK:

But there is no written record to document that; isn't that right?

288 PROF. MACDONELL:

Not that I'm aware of.

289 MS. CLARK:

And the only written record that you made concerning your observations of the socks with respect to the nature of the stain and the little balls is the report dated July 11th; isn't that right?

290 PROF. MACDONELL:

That's correct.

291 MS. CLARK:

So between April the 2nd and July 11th, you made the observations on April the 2nd, but you wrote nothing down concerning your observation of the little balls, the voids, the lateral swipe until July 11th; is that right?

292 PROF. MACDONELL:

That's correct. I wasn't in the country.

293 MS. CLARK:

So you wrote that report from memory; is that right?

294 PROF. MACDONELL:

Yes. And a very, very few lines that I wrote in my description which are in your possession.

KEY QUOTE
295 MS. CLARK:

I'm sorry?

296 PROF. MACDONELL:

The few notes that I made are in your possession. I referred to them.

297 MS. CLARK:

No. I gave them back to you, didn't I?

298 PROF. MACDONELL:

Oh, I'm sorry. Yes, you did. Thank you.

299 MS. CLARK:

But these notes do not contain--excuse me, sir--a description of evidence, do they?

300 PROF. MACDONELL:

No. Just sketch.

301 MS. CLARK:

Matter of fact, those notes just document your receipt of the evidence and the date and time and what you got; isn't that right?

302 PROF. MACDONELL:

Well, it lists the time that was spent examining the two items, 42a and b, according to my notes, and the length of time.

303 MS. CLARK:

Now, your examination on April the 2nd was done with a very high intensity light; is that right?

304 PROF. MACDONELL:

Yes. High intensity.

305 MS. CLARK:

And microscope; is that right?

306 PROF. MACDONELL:

Correct.

307 MS. CLARK:

And you will agree, will you not, that the observation of blood on those socks was a difficult one in view of the dark color of the fabric, sir?

308 PROF. MACDONELL:

Not when you've got good high intensity illumination. It would be difficult in this room, yes. But under the conditions that you would use for an examination, it was not difficult. It was straightforward.

309 MS. CLARK:

And, again, though, when you're talking about high intensity light, can you explain to the jury what you mean by that?

310 PROF. MACDONELL:

High intensity is more lumens per square centimeter. A pocket light like this can give extremely high intensity right at the end, much more than a thousand watt bulb would give here on the ceiling if the bulb was on the ceiling. So high intensity is the concentration of light in a given area, and it's expressed physically as lumens per square centimeter.

311 MS. CLARK:

So it would be--if we were to light up this courtroom with that kind of high intensity light, would we all be wearing sunglasses?

312 PROF. MACDONELL:

We ought to be. I would be if I could or I'd close my eyes.

313 MS. CLARK:

Now, with respect to the distinction between swipe and compression, sir--

314 (Brief pause.)
315 MS. CLARK:

You did indicate that you observed crime scene photographs, correct?

316 PROF. MACDONELL:

Yes, I did.

317 MS. CLARK:

Can I approach?

318 THE COURT:

I think you'd better.

Key Quotes (5)

Prof. Herbert MacDonell
It was written for attorneys. Not scientists.
MacDonell's attempt to explain why his July 11 report said 'swipe' while he testified to 'compression' — effectively conceding the report was imprecise.
Prof. Herbert MacDonell
There's no change. They're both transfers.
MacDonell's defense of the swipe/compression discrepancy, which Clark systematically exposed as contradicting his own repeated distinctions during direct testimony.
Marcia Clark
If it makes no difference, sir, then why testify before this jury repeatedly that it was a compression and not a swipe if it doesn't matter?
The sharpest formulation of Clark's core attack — MacDonell emphasized the distinction on direct but retreated from it on cross.
Prof. Herbert MacDonell
Yes. And a very, very few lines that I wrote in my description which are in your possession... Oh, I'm sorry. Yes, you did. Thank you.
MacDonell accidentally accuses Clark of withholding his notes — then immediately realizes she had returned them to him.
Prof. Herbert MacDonell
No. Again, I was not describe. I made a couple of very simple sketches and Dr. Lee made all the tests and made all the detailed notes.
MacDonell confirms his own notes contain no description of the 'little balls,' deflecting to Lee — but Lee's notes are then shown to contain no such description either.

Evidence (6)

People's 555
Photograph of Dr. Henry Lee manipulating the sock on February 16, 1995
discussed; MacDonell agrees Lee appears to be turning it inside out
People's 556
Photograph of Dr. Lee taking a picture through a stereobinocular microscope on February 16, 1995
discussed; establishes Lee examined socks under microscope before April 2nd examination
1278
Enlarged photograph showing 'little ball' (red ball) on the inside of the sock, taken April 2, 1995
discussed; Clark notes only one such photograph was taken despite six or seven balls being observed
Informal
MacDonell's expert report dated July 11, 1995
used to impeach — report says 'swiped,' testimony says 'compression'; also contains no mention of voids or little balls
Informal
MacDonell's contemporaneous notes from April 2, 1995 examination
produced in court; shown to contain only simple sketches and time logs, no description of little balls, voids, or transfer type
Informal
Dr. Henry Lee's notes from April 2, 1995 examination
reviewed on stand; contain references to 'little tiny dots' and photographs taken, but no description of lateral swipe, voids, or compression transfer

Notable Exchanges (4)

Marcia ClarkProf. Herbert MacDonell
Clark reads paragraph 4 of MacDonell's own report aloud — it uses the word 'swiped' — and then confronts him with the fact that he testified on direct it was a compression, not a swipe. MacDonell tries to minimize the distinction, eventually claiming 'a swipe is a compression with lateral motion,' but Clark boxes him in by pointing out he made the distinction himself, repeatedly, before this jury.
devastating
Marcia ClarkProf. Herbert MacDonell
Clark establishes that the report was written entirely from memory three months after the examination, with no contemporaneous documentation of the 'little balls,' 'voids,' or the nature of the transfer — the three pillars of MacDonell's direct testimony.
strategic
Marcia ClarkProf. Herbert MacDonellPeter Neufeld
Dispute over whether MacDonell's notes had been turned over to the prosecution. Neufeld asserts they had been; Clark says they had not. Judge Ito defers resolution, telling them to proceed and take it up later.
procedural
Lance A. ItoMarcia ClarkProf. Herbert MacDonellScott Gordon
Brief confusion over whether the red-ball photograph was exhibit 1278 or 1279 — Clark says 1279, MacDonell corrects her to 1278, and Gordon confirms 1278. Ito had to intervene to get the record straight.
procedural

Light Moments (4)

Lance A. Ito / Marcia Clark
Clark attempts a grammatically tortured double-negative question ('you have not said that you make that assumption; have you not, sir?') and Ito steps in with deadpan humor: 'You can not say that you haven't said it; have you not?' Clark responds: 'No. See? Clear to me.'
Prof. Herbert MacDonell
MacDonell explains high-intensity light using a pocket flashlight analogy, then Clark asks if they'd all need sunglasses if the courtroom were lit that way. MacDonell: 'We ought to be. I would be if I could or I'd close my eyes.'
Prof. Herbert MacDonell
MacDonell accidentally accuses Clark of withholding his notes, then immediately realizes she'd just handed them back to him seconds earlier: 'Oh, I'm sorry. Yes, you did. Thank you.'
Prof. Herbert MacDonell
MacDonell says 'I hope so' when Clark asks if he is aware the Defense has retained him as an expert.

Credibility Attacks (4)

⚔ Prof. Herbert MacDonell
prior inconsistent statement
Clark uses MacDonell's own signed report, which describes the stain as 'swiped,' to contradict his direct testimony characterizing it as a compression rather than a swipe. MacDonell attempts to minimize the distinction but cannot explain why he repeatedly emphasized it before the jury if it were truly irrelevant.
⚔ Prof. Herbert MacDonell
omissions in documentation
Clark establishes that neither MacDonell's report nor his contemporaneous notes nor Dr. Lee's notes contain any description of the 'little balls,' 'voids,' or the swipe/compression distinction — the core elements of his direct testimony — despite the report being presented as an accurate summary of his findings.
⚔ Prof. Herbert MacDonell
memory-based report
Clark establishes that MacDonell's July 11 report was written entirely from memory, approximately three months after the April 2 examination, with only a few lines of contemporaneous notes (sketches and time logs) to support it.
⚔ Prof. Herbert MacDonell
failure to file addendum
Clark presses MacDonell on the fact that he never notified the prosecution — through an amended report or addendum — that he was changing or refining his characterization of the stain from swipe to compression before taking the stand.
