Cross-examination of Professor Herbert MacDonell (part 2)

Witness: Prof. Herbert MacDonell
Examiner: Marcia Clark
Called by: Defense • Date: Monday, July 31, 1995 • Utterances: 195
Marcia Clark cross-examines defense bloodstain expert Prof. Herbert MacDonell about his conclusions regarding microscopic 'little balls' of dried red material found on the inner surface of the sock. Clark systematically challenges MacDonell's methodology by establishing he had no knowledge of the sock's handling history — including whether it had been frozen/unfrozen, twisted, or examined microscopically by Dr. Lee before his April 2nd inspection. The examination ends abruptly with Neufeld calling a sidebar after Clark attempts to introduce photographs showing Dr. Lee manipulating the sock.
1 THE COURT:

All right. Thank you, ladies and gentlemen. Please be seated. Mr. MacDonell, would you resume the witness stand, please. And, Miss Clark, you may continue with your cross examination.

2 MS. CLARK:

Thank you, your Honor.

3 MS. CLARK:

Now, when we left off, sir, we were discussing the fact that you were not aware of the history of the sock before you saw it on April 2nd, 1995.

4 MR. NEUFELD:

Object--

5 MS. CLARK:

Do you recall that?

6 MR. NEUFELD:

Objection. He didn't say anything about history.

7 THE COURT:

Overruled.

8 PROF. MACDONELL:

No, I do not know the history prior to that, how it was stored, maintained, no.

9 MS. CLARK:

And you made no effort to determine what the history of the sock was with respect to how it was handled before you saw it on April 2nd of 1995?

10 THE COURT:

All right, we've established that already. Let's proceed.

11 MS. CLARK:

I think I only asked him about Greg Matheson. I would have liked--

12 THE COURT:

Let's proceed.

13 MS. CLARK:

Well, can you tell us, sir, what effort you made to determine what the history of the handling and testing of that sock was before you saw it on April 2nd, 1995?

14 PROF. MACDONELL:

I did not make any determination of the history. My purpose there was to examine it as it was in the condition received.

15 MS. CLARK:

In that case, sir, then you can not tell us whether the condition that you observed on April 2nd was there before August 4th, 1994?

16 PROF. MACDONELL:

No. Of course not.

17 (Brief pause.)
18 THE COURT:

Miss Clark.

19 MS. CLARK:

Yes, your Honor. I'd ask that this photograph be marked People's next in order, People's 5--

20 THE COURT:

553.

21 MS. CLARK:

-53?

22 (Peo's 553 for id = photograph)
23 THE COURT:

Appears to be a photograph of a sock with a q-tip.

24 MS. CLARK:

Do you recognize what's being done in this photograph, sir?

25 PROF. MACDONELL:

Yes, I do.

26 MS. CLARK:

That's a phenolphthalein test, isn't it?

27 PROF. MACDONELL:

Well, it's the sampling prior to the phenolphthalein test.

28 MS. CLARK:

Yes. And the phenolphthalein test is a presumptive test for blood; is it not?

29 PROF. MACDONELL:

That's correct.

30 MS. CLARK:

Now, do you--

31 MS. CLARK:

If you would focus in, Jonathan, on that. Thanks.

32 MS. CLARK:

Do you see that spot there, sir?

33 PROF. MACDONELL:

Well, I did.

34 MS. CLARK:

Used to. Do you see it?

35 PROF. MACDONELL:

I see--yeah. There it comes. I see a spot, yes.

36 MS. CLARK:

All right. Does that appear to be water, sir?

37 MR. NEUFELD:

Objection, your Honor.

38 THE COURT:

Sustained.

39 MR. NEUFELD:

No foundation for that.

40 THE COURT:

Sustained.

41 MS. CLARK:

Does it look wet?

42 MR. NEUFELD:

Objection, your Honor.

43 THE COURT:

Sustained. Sustained.

44 MS. CLARK:

Appear wet?

45 THE COURT:

Yes.

46 MS. CLARK:

What does it look like to you?

47 PROF. MACDONELL:

Looks like a yellow ellipse.

48 MS. CLARK:

And does it look like liquid?

49 MR. NEUFELD:

Objection, your Honor.

50 THE COURT:

Sustained.

51 MS. CLARK:

Is there a form of phenolphthalein test that uses distilled water, sir?

52 PROF. MACDONELL:

Yes. Certainly. You have to have a solvent, either phenolphthalein or distilled water.

53 MS. CLARK:

And if that is the test being--does that appear to be the test being performed here, sir?

54 MR. NEUFELD:

Objection, your Honor, what appears.

55 THE COURT:

Overruled.

56 PROF. MACDONELL:

As stated before, it appears to me to be the sampling phase. First you sample the material and then you analyze it by adding the reagent to it. This would be just sampling, removing a suspect stain or a portion thereof for testing.

57 MS. CLARK:

Okay. And you remove the suspect stain or portion thereof by adding--by using a damp q-tip to sample the area; is that correct?

58 PROF. MACDONELL:

That's correct. A damp q-tip or whatever. Filter paper you can use also.

59 MS. CLARK:

In this case, they used what appears to be a damp q-tip; would you agree, sir?

60 PROF. MACDONELL:

I would agree it's a q-tip and it apparently has been damped. It should be if it's going to be used.

61 MS. CLARK:

Now, are you aware of the date on which this photograph was taken?

62 PROF. MACDONELL:

No.

63 MS. CLARK:

Now, sir, would it be important to you to know whether as of the date--after the date of this photograph, assumed for the hypothetical that it's August 4th, 1994--

64 MR. NEUFELD:

Objection. There's been no evidence as to when this particular test was made.

65 THE COURT:

Overruled. Overruled.

66 MS. CLARK:

--that the socks were frozen and unfrozen, twisted, cut?

67 MR. NEUFELD:

Objection as to "Twisted."

68 THE COURT:

Sustained. Rephrase the question.

69 MR. NEUFELD:

Objection as to "Cut."

70 THE COURT:

Overruled.

71 MR. NEUFELD:

At this point.

72 THE COURT:

Overruled.

73 MS. CLARK:

Would you agree, sir, that it would be important to know that after the point of the testing shown in this photograph, the socks had been frozen and unfrozen repeatedly? Would that be good for you to know?

74 PROF. MACDONELL:

Well, again, this is not testing in the photograph. The test followed the photograph. It would not be important for me to know because I saw what I saw at the time I examined it. If you want me to speculate as to what could have caused it, then if I knew certain factors, I might be in a position to speculate.

75 MS. CLARK:

Then you would agree, sir, that your lack of knowledge as to whether or not the socks had been frozen and unfrozen repeatedly would have an impact on your ability to give us some opinion as to how the microbe--the little balls that you saw got to be on the inner side of the sock that you saw on April 2nd, correct?

76 MR. NEUFELD:

Objection, your Honor.

77 THE COURT:

What's the objection?

78 MR. NEUFELD:

Objection as to the form of the question.

79 THE COURT:

Overruled.

80 PROF. MACDONELL:

Freezing and thawing I do not conceive as a mechanism that would allow the things that I observed in the cut-out portion on the opposite side to have been formed. I can't imagine a mechanism by simply freezing and thawing unless you purposely put it in a high-humidity cabinet. That could cause that. I just don't see that that's a factor.

81 MS. CLARK:

So it's your opinion then, sir, that even though you're not aware of how many times it was frozen and unfrozen, you are willing to give the opinion to this jury that that would have no impact on whether or not those little balls would appear on the other side of the sock; is that correct?

82 MR. NEUFELD:

Objection. Argumentative.

83 THE COURT:

Overruled.

84 PROF. MACDONELL:

The statement I made did not say "Have no effect." I said that might explain an effect, but I can not imagine how simply freezing and thawing or the number of times it's done would have any significant effect upon creating what I observed when I looked at them on April 2nd.

85 MS. CLARK:

But you don't know, do you, sir?

86 PROF. MACDONELL:

Of course not.

87 MS. CLARK:

And you can not tell this jury whether or not that's how those little balls came to be on the other side of the stain; isn't that right, sir?

88 MR. NEUFELD:

Objection. Asked and answered twice.

89 THE COURT:

Overruled.

90 PROF. MACDONELL:

I don't know what you mean by "That." You'll have to explain. Is "That" supposed to mean a mechanism? Would you rephrase that, please?

91 MS. CLARK:

You can not tell us, sir, whether or not--you can not state to this jury that the freezing and unfreezing process absolutely did not cause the appearance of those little balls on the inside of the sock that you saw on April 2nd, 1995; isn't that true?

92 MR. NEUFELD:

Objection. Asked and answered twice.

93 THE COURT:

Overruled.

94 PROF. MACDONELL:

No scientist can state absolutes. Of course not.

KEY QUOTE
95 MS. CLARK:

And you did not inquire--you examined these socks with Dr. Lee on April 2nd; isn't that right?

96 PROF. MACDONELL:

That is correct.

97 MS. CLARK:

Did you discuss with him his examination of the socks on February 16th, 1994--5?

98 PROF. MACDONELL:

No.

99 MS. CLARK:

Were you aware of his examination of the socks that he had conducted on February 16th, 1995?

100 PROF. MACDONELL:

To the extent that he just observed them. I do not believe he made a microscopic examination at that time. That is my best recollection.

101 MS. CLARK:

But you do not know?

102 PROF. MACDONELL:

I don't recall further. So I don't know.

103 MS. CLARK:

And you do not know if he during the process of his experiment on February 16, 1995 twisted and pulled the socks in an effort to get a better look at any side of it or any aspect of it, do you?

104 MR. NEUFELD:

Objection. Assumes facts not in evidence.

105 THE COURT:

Sustained. Sustained.

106 MS. CLARK:

Are you aware, sir, of the fact that LAPD set up a microscope for Dr. Lee to use in his February 16th examination?

107 PROF. MACDONELL:

No. I was not aware of that.

108 MS. CLARK:

And in the course of a microscopic examination, sir, in your experience, can it occur that material or fabric will be pulled or twisted in an effort to get a certain area under the field of view?

109 PROF. MACDONELL:

Certainly.

110 MS. CLARK:

And would it be important to know whether that that had occurred on multiple occasions with this particular sock?

111 PROF. MACDONELL:

It could be, but I can't imagine exactly how.

112 MS. CLARK:

But it could add important information, sir, with respect to determining how those little microbes got onto the side of the sock when you observed them in 1995?

113 MR. NEUFELD:

Objection.

114 THE COURT:

Sustained. Sustained. Rephrase the question.

115 MS. CLARK:

I'm sorry. Little balls.

116 PROF. MACDONELL:

They're not microbes. Microbes are alive. Now I forgot the question.

KEY QUOTE
117 MS. CLARK:

All right. Could it be important information whether or not the sock was repeatedly manipulated and twisted during microscopic--repeated microscopic examinations to determine how those little balls got onto the side of the sock when you observed them on April 2nd, 1995?

118 PROF. MACDONELL:

I can't imagine how. I really don't see how manipulating the fabric could create dried balls of red fluid inside of the sock. It may be possible, but I have no idea what the mechanism would be that could cause those to form simply by manipulation. They were dried when--and they were wet and they dried.

KEY QUOTE
119 MS. CLARK:

Let me ask you something, sir. You said you observed one of those little balls to be adherent to the fiber; is that correct?

120 MR. NEUFELD:

Objection. That is not his testimony.

121 THE COURT:

Overruled.

122 PROF. MACDONELL:

I observed several, I think half a dozen at least. We photographed the one that showed the bonding to the fiber the most distinctly.

123 MS. CLARK:

Okay. Is it--sir, based on your examination, one was bonded well enough to photograph; is that correct?

124 MR. NEUFELD:

Objection. That's not his testimony.

125 THE COURT:

Overruled.

126 PROF. MACDONELL:

I think they were all bonded, but this one showed the bonding to a fiber that was also part of the woven thread. That's the reason it was selected.

127 MS. CLARK:

And that's the reason you took only one photograph although you saw six or seven of these little balls; is that right?

128 PROF. MACDONELL:

I didn't take the photographs. Dr. Lee actually clicked them off. I observed them.

129 MS. CLARK:

You observed them, but there was only one photograph taken; is that right, sir?

130 PROF. MACDONELL:

It's the only one that I have seen. I think it's the best representation and I'm sure that's why he enlarged it.

131 MS. CLARK:

Is your answer yes?

132 PROF. MACDONELL:

What was the question? Did I observe just one?

133 MS. CLARK:

No. No. Mr. MacDonell, please listen to the question. I asked you whether you took only--there was only one photograph taken of those little balls that you saw on the inner surface of the sock.

134 PROF. MACDONELL:

I answered that when I said Dr. Lee took it. I did not take any.

135 MS. CLARK:

The question is, only one photograph, correct?

136 PROF. MACDONELL:

To the best of my knowledge.

137 MS. CLARK:

And that one photograph was taken because in your opinion or in your collective opinion, that demonstrated most clearly the bonding of that little ball; is that correct?

138 PROF. MACDONELL:

That is correct.

139 MS. CLARK:

Now, let me ask you something. With respect to that little ball that you saw bonded, what tests did you perform to determine whether it was in fact adherent to the fabric or simply lying in the weave where you saw it?

140 PROF. MACDONELL:

It seems to surround the fiber or the thread-like material to which it is bonded, and it didn't move. So it didn't fall off. We're dealing with something extremely small. We didn't do any testing to dry to abrade it to perhaps fracture it. But it's exceedingly small. We did no actual testing except observation.

141 MS. CLARK:

All right. As a matter of fact, those little balls that you saw--you said six or seven of them?

142 PROF. MACDONELL:

Yes.

143 MS. CLARK:

Did you make any effort to quantify those little balls?

144 PROF. MACDONELL:

As to volume?

145 MS. CLARK:

Yes. As to volume, sir.

146 PROF. MACDONELL:

No.

147 MS. CLARK:

If you took those six or seven little balls and put them all in a purple top tube and stacked them on top of each other, could you see them?

KEY QUOTE
148 PROF. MACDONELL:

Not without a microscope or unless you're extremely myopic.

KEY QUOTE
149 MS. CLARK:

And yet the stain on the outside of the opposite side of the sock you said was 50 microliters, 60 maybe?

150 PROF. MACDONELL:

Yes.

151 MS. CLARK:

And all you had were those six little balls, six or seven little balls that you couldn't even see if stacked up together with the naked eye; is that right?

152 PROF. MACDONELL:

Or grouped, yes.

153 MS. CLARK:

Now, with respect to the manipulation of the sock, sir, you indicated that you--strike that. These socks, they were stretchy, elastic in nature; were they not?

154 PROF. MACDONELL:

Yes.

155 MS. CLARK:

Blood when it dries is not elastic, is it, sir?

156 PROF. MACDONELL:

No.

157 MS. CLARK:

Now, if you were to have blood dry on a sock and then you were to stretch it, blood might flake off, if even in only microscopic amounts. Would that be true, sir?

158 PROF. MACDONELL:

Yes, it is.

159 MS. CLARK:

And if the sock is stretched in some fashion, which causes the blood to flake and then the sock is compressed through storage in a bag, you can--there will be some microscopic or some flaking happening of the blood that has dried on the sock; isn't that correct?

160 PROF. MACDONELL:

That's correct. There should be.

161 MS. CLARK:

And if in fact the blood that has hit the outer surface of the sock has seeped through to the inside, if it rubs against the other side in a dried condition causing--by friction, there will be some flaking as well, would there not, even if only in microscopic in amount?

162 PROF. MACDONELL:

Well, it's even simpler than that. It wouldn't have to flake off and go through the sock because when it dries, it's through the sock to begin with. So could flake off from the inside of the outside surface at that point. And then if it landed on the inside, you would have some flakes on the side opposite the inside. Yes, that could happen.

163 MS. CLARK:

And you indicated that you were not present when Dr. Lee did his examination of the socks on February 16th, 1995; is that right, sir?

164 PROF. MACDONELL:

That is correct.

165 MS. CLARK:

Now, on the date that you did the examination with him, did you turn the socks inside out?

166 PROF. MACDONELL:

I think we did after the initial photographs were taken.

167 MS. CLARK:

And when you say the initial photographs were taken, are you talking about the photographs of the little balls?

168 PROF. MACDONELL:

Yes. We--I believe we took all the photographs before we did any what you could call stretching or manipulation of the socks. We left them quite flat as we took them out.

169 MS. CLARK:

Do you know whether anyone turned those socks inside out or twisted them in any fashion before you made that examination on April 2nd, 1995?

170 PROF. MACDONELL:

No, I don't.

171 MS. CLARK:

Would that be information that you would like to have, sir, in forming your opinion as to how those little balls got onto that side of the sock?

172 PROF. MACDONELL:

No.

173 MS. CLARK:

You don't think that would be important to know?

174 PROF. MACDONELL:

No. Not unless you added many factors such as if the socks were wet and you turn them inside out. That might make a difference. But you're exposing the inside where I detected these small balls of red material to the outside at that point. So you're defeating the purpose of transfer.

175 MS. CLARK:

Uh-huh.

176 PROF. MACDONELL:

That would no longer be in contact with the area that was stained. So you're losing ground that way if you're trying to transfer them.

177 MS. CLARK:

No. You're--let me ask you this, sir. You don't know whether they were wet on some occasion after the blood was detected on August 4th with that q-tip, correct?

178 MR. NEUFELD:

Objection. No foundation for that.

179 THE COURT:

Sustained. Rephrase the question.

180 MS. CLARK:

Well, let me--

181 MS. CLARK:

Your Honor, I have a series of three photographs I'd like to show to the witness. I'm going to show them to counsel. Be marked People's 554--

182 THE COURT:

554.

183 MS. CLARK:

--555 and 556.

184 (Peo's 554, 555 and 556 for id = photographs)
185 MS. CLARK:

554, your Honor?

186 THE COURT:

Yes. 554 is the first one.

187 MS. CLARK:

All right. Sir, I'm going to show you a photograph. Do you recognize--do you recognize the person in that photograph, sir?

188 PROF. MACDONELL:

Yes, I do.

189 MS. CLARK:

Who's that?

190 PROF. MACDONELL:

That's Dr. Henry Chung Lee.

191 MS. CLARK:

All right. Did you see him perform the manipulation with the sock that he used in this photograph in your presence on April 2nd?

192 PROF. MACDONELL:

No, I did not.

193 MS. CLARK:

Did anyone--were you ever--

194 MR. NEUFELD:

Your Honor--I'm sorry, your Honor. Can we have a sidebar?

195 THE COURT:

Let me see the photographs. With the court reporter, please.

Key Quotes (5)

Prof. Herbert MacDonell
No scientist can state absolutes. Of course not.
MacDonell is forced to concede he cannot rule out that freezing/unfreezing caused the microscopic balls, undermining the certainty of his planted-blood conclusion.
Prof. Herbert MacDonell
They're not microbes. Microbes are alive. Now I forgot the question.
MacDonell corrects Clark's terminology mid-testimony, momentarily breaking his own concentration — a small humanizing slip that also shows he's attentive to precision.
Marcia Clark
If you took those six or seven little balls and put them all in a purple top tube and stacked them on top of each other, could you see them?
Clark uses a vivid analogy to illustrate how vanishingly small the evidence for planted blood actually is, contrasting the six invisible balls against a 50-60 microliter stain on the outer sock.
Prof. Herbert MacDonell
Not without a microscope or unless you're extremely myopic.
MacDonell's wry answer confirms Clark's point: the physical quantity of the alleged transfer evidence is essentially invisible to the naked eye.
Prof. Herbert MacDonell
I can't imagine how. I really don't see how manipulating the fabric could create dried balls of red fluid inside of the sock.
MacDonell holds his ground but frames his opinion in imagination rather than physical certainty, giving Clark further openings on cross.

Evidence (2)

People's 553
Photograph of the sock with a q-tip, showing sampling phase prior to phenolphthalein presumptive blood test
introduced and discussed; Clark uses it to establish a timeline anchor for the sock's condition
People's 554, 555, 556
Series of photographs showing Dr. Henry Lee manipulating the sock, apparently from his February 16, 1995 examination
introduced for identification; examination cut off by sidebar before testimony on them could proceed

Notable Exchanges (3)

Marcia ClarkProf. Herbert MacDonell
Clark walks MacDonell through every alternative mechanism that could explain the 'little balls' — freezing/thawing, stretching elastic fabric, microscopic manipulation during prior exams — and MacDonell concedes he cannot rule any of them out with certainty, only that he cannot 'imagine' the mechanism.
strategic
Marcia ClarkProf. Herbert MacDonell
Clark establishes that MacDonell saw six or seven balls, photographed only one, performed no quantification of their volume, and that their combined mass would be invisible to the naked eye — all while a 50-60 microliter stain sat on the opposite side of the sock.
revealing
Marcia ClarkProf. Herbert MacDonell
MacDonell himself acknowledges a plausible transfer mechanism — blood dried through the fabric could flake off the inner surface of the outer layer and land on the inside — effectively conceding one of Clark's theories under his own analysis.
revealing

Light Moments (2)

Prof. Herbert MacDonell
MacDonell corrects Clark's use of 'microbes' ('They're not microbes. Microbes are alive.') and then admits he lost track of the question entirely.
Prof. Herbert MacDonell
When asked if invisible stacked balls could be seen, MacDonell deadpans: 'Not without a microscope or unless you're extremely myopic.'

Credibility Attacks (3)

⚔ Prof. Herbert MacDonell
methodology challenge / incomplete investigation
Clark establishes MacDonell never inquired into the sock's chain of custody, how many times it was frozen/unfrozen, or what Dr. Lee did to it during his February 16 examination — leaving his conclusions about how the 'little balls' got there scientifically unsupported.
⚔ Prof. Herbert MacDonell
minimization of physical evidence
Clark highlights that the entire basis for planted-blood allegations rests on six or seven balls too small to see with the naked eye, no volume testing, and a single photograph — against a 50-60 microliter stain on the other side.
⚔ Prof. Herbert MacDonell
prior inconsistent characterization
Neufeld objects twice that Clark is mischaracterizing MacDonell's direct testimony about the ball being 'adherent to the fiber' — both objections overruled, but the friction highlights ambiguity in the original testimony.

Witness Demeanor

(Brief pause.) — after MacDonell acknowledges he cannot know the sock's condition before August 4, 1994
Witness repeatedly asks Clark to rephrase or clarify questions, suggesting careful defensiveness under pressure
