Cross-examination of Professor Herbert MacDonell (part 4)

Witness: Prof. Herbert MacDonell
Examiner: Marcia Clark
Called by: Defense • Date: Monday, July 31, 1995 • Utterances: 191
Marcia Clark continued cross-examination of defense bloodstain expert Prof. Herbert MacDonell, pressing him on the distinction between his report's characterization of the sock bloodstain as a 'swipe' versus his trial testimony calling it a 'compression.' Clark then pivoted to attacking MacDonell's academic credentials, highlighting that his professorial positions were part-time night-school roles at small or now-defunct institutions, and that he lacked a graduate degree when heading his sole-faculty chemistry department.
1 THE COURT:

All right. Proceed. All right. Miss Clark, you may conclude.

2 MS. CLARK:

All right, sir. Now, in characterizing the stain on the outside as a swipe and then changing your testimony in court here to a compression, were you--

3 MR. NEUFELD:

Objection, your Honor, to the characterization.

4 THE COURT:

Sustained. Rephrase the question.

5 MS. CLARK:

You initially characterized the stain as a swipe, is that correct, in your report?

6 PROF. MACDONELL:

In the report, yes.

7 MS. CLARK:

And then you came in and you testified to say that it was a compression and not a swipe; is that correct?

8 PROF. MACDONELL:

No. It could be a swipe if the leading trailing edges are uniform as they appear to be in the enlarged photographs that I found that Dr. Lee had taken.

9 MS. CLARK:

So you're saying it could be either one at this point?

10 PROF. MACDONELL:

Yes. They're the same thing. They're both compression transfers. One has a little more lateral motion than the other.

KEY QUOTE
11 MS. CLARK:

One has a little more pressure than the other, doesn't it, sir?

12 PROF. MACDONELL:

Not necessarily, no. You have to have pressure or you won't get any transfer at all.

13 MS. CLARK:

All right. So compression then could be from touching?

14 PROF. MACDONELL:

Yes. That's compression.

15 MS. CLARK:

Could be from pressing?

16 PROF. MACDONELL:

Touching is pressing.

17 MS. CLARK:

Okay. So you don't--what you're saying, sir, is that there's no particular amount of pressure applied. Any pressure will indicate compression; is that right?

18 PROF. MACDONELL:

There has to be sufficient pressure to transfer a liquid to the surface, and that's very minimal when you have a liquid.

19 MS. CLARK:

In characterizing it as a compression instead of a swipe in your direct examination testimony, were you attempting to be more helpful to the Defendant?

20 MR. NEUFELD:

Objection.

21 THE COURT:

Sustained. Argumentative.

22 MS. CLARK:

Well, in attempting to charac--excuse me. Not attempting. In characterizing the stain as a compression as opposed to a swipe, were you attempting to make it sound more sinister, Mr. MacDonell?

23 MR. NEUFELD:

Objection, your Honor.

24 THE COURT:

Overruled.

25 PROF. MACDONELL:

I am a scientist, not an advocate, and I am not changing, modifying or correcting anything for anyone's benefit except to clarify the matter to the jury. That's my purpose here.

KEY QUOTE
26 MS. CLARK:

Nevertheless, you have--would you answer the question, sir? Do you think in your mind that saying it is a compression makes it sound more sinister than a swipe?

27 MR. NEUFELD:

Objection. Argumentative.

28 THE COURT:

Sustained. Sustained.

29 MS. CLARK:

You saw photographs of the crime scene; have you not?

30 PROF. MACDONELL:

Yes, I have.

31 MS. CLARK:

And let me ask you this, sir. If someone wearing the socks that you saw were to step near to the body of the victim Nicole Brown Simpson, near enough for the ankle bone to come in contact with her bloody hand, could that cause a compression transfer?

32 PROF. MACDONELL:

Certainly.

33 MS. CLARK:

Could it also cause a swipe?

34 PROF. MACDONELL:

Yes.

35 MS. CLARK:

If she were to reach a bloody hand out and touch her thumb or finger or hand to the ankle of Mr. Simpson wearing those socks, could that cause a compression or a swipe?

36 MR. NEUFELD:

Objection. No foundation.

37 THE COURT:

Sustained. Rephrase the question. Rephrase the question.

38 MS. CLARK:

Oh. If Nicole Brown Simpson reached out a bloody hand to touch the ankle of the murderer wearing those socks, could that cause a compression or a swipe transfer?

39 MR. NEUFELD:

Objection. No foundation.

40 THE COURT:

Overruled.

41 PROF. MACDONELL:

Certainly it could. Anything that has blood on it can either be projected and touch the area that's stained or this area that's stained could have come in contact with it. It's simple transfer.

42 MS. CLARK:

Well, for example, I see the way you're sitting, sir. I can't demonstrate this obviously. But if you were to--the jury--

43 MS. CLARK:

Can the jury see?

44 MS. CLARK:

If you were to move your knee back, sir--

45 PROF. MACDONELL:

My knee?

46 MS. CLARK:

Yeah--to where your ankle bone, the bony protrusion of your ankle was on top of your knee, would that--could that produce a compression or a swipe?

47 PROF. MACDONELL:

If one surface was wet, yes.

48 MS. CLARK:

Now, you noted, sir, that the stain appeared to be in the area of the ankle where there would be the bony protrusion of the ankle, correct?

49 PROF. MACDONELL:

It appeared to be in that general area. I don't know the socks were put on, if it would be at the outer-most portion or the apex of that circular area. But in that general area, yes. It very well could be at the extreme of the ankle bone.

50 MS. CLARK:

And by the "Extreme," you mean the highest point, the point that protrudes the most?

51 PROF. MACDONELL:

Correct. On either side of the leg. There's one on each side.

52 MS. CLARK:

Right. And by the way, sir, by looking at the sock, could you tell whether it was the right or left sock, sock a that we're talking about here?

53 PROF. MACDONELL:

No.

54 MS. CLARK:

Okay. By the way--and did you happen to have a look at a photograph of the socks in the condition in which they were found on the bedroom floor?

55 PROF. MACDONELL:

I've seen some pictures of it, yes.

56 MS. CLARK:

Let me--this has been marked so many times, I hate to mark it again, but--it's People's 127 already marked. I have one handy.

57 THE COURT:

All right. 127.

58 MS. CLARK:

Let me ask you, sir, if you've seen this photograph before.

59 PROF. MACDONELL:

Yes, I have, or one just like it.

60 MS. CLARK:

Now, you've seen the socks in person, correct?

61 PROF. MACDONELL:

Yes, I have.

62 MS. CLARK:

And do they appear to be inside out in this photograph, sir?

63 THE COURT:

Would you like a magnifying glass?

64 PROF. MACDONELL:

I've got one, but I don't need it. I honestly can't tell. If I had the socks to compare to this, I might be able to. But I--I don't think so. It's just heavier fabric in the heal and the toe. But they certainly--the upper portion seems to be inside out, but the--to tell whether the whole sock is inside out or not that's lying down, I honestly can't tell you.

65 MS. CLARK:

Nevertheless, they are lying flat on the--somewhat crumpled, but lying on the floor, correct?

66 PROF. MACDONELL:

One is. One is more or less folded over. I don't know which side is up or down. It would appear that it is the left side of the one that is spread out the most that is down, but the other one is kind of wadded up.

67 MS. CLARK:

And so the jury knows what we're referring to, I'm going to put it on the monitor. I wanted you to see it, sir, because I don't know if your monitor is going to give you as much resolution as you get looking at it up close. Now, when you said that one appeared to be more crumpled up, you were referring to the one up on top; were you not, sir?

68 PROF. MACDONELL:

Yes, I was.

69 MS. CLARK:

All right. And--now, let me ask you a question. If you have--may be just a matter of common sense, but if you have a bony protruding area on an item of clothing like around the ankle bone, you're wearing a sock, that area is sticking out, that area would be more likely to get blood assuming blood is in the area of the feet. Would that be a fair statement?

70 PROF. MACDONELL:

Yes, if it was transferred.

71 MS. CLARK:

Uh-huh.

72 PROF. MACDONELL:

But spattering or something would be not dependent upon that, but brushing against something, yes, the bone sticks out further.

73 MS. CLARK:

Right. So the bone area where you found that bloodstain would be the place that would be most likely to receive blood from a transfer if you're in the area of blood or a bloody body, correct?

74 PROF. MACDONELL:

Yes. If that transfer again is in--right on the ankle bone. I think it would make a difference whether you had it on the right or left foot though. I think there's a slight difference. But I don't know. It's in that area. I don't know that it's at the peak of the bone as I say. Of course, the sock is elastic. So you could adjust it so it was or was not.

75 MS. CLARK:

But it was in that general area, you would agree, sir?

76 PROF. MACDONELL:

Yes, I would.

77 MS. CLARK:

So if that sock was worn to--in the commission of a murder and the feet were in the area of a bloody victim, an area that would swipe the bloody victim, then the area where you found the stain is the area most likely to receive that swipe or compression, correct?

78 MR. NEUFELD:

Objection. Compound.

79 THE COURT:

Overruled.

80 PROF. MACDONELL:

I would say yes.

81 MS. CLARK:

Now, let me ask you a couple other questions, sir. As a matter of practicality, if someone is sweating and they are wearing socks of this kind of nylon nature, as a practical matter, is it not more difficult to take socks off of a sweaty foot?

82 MR. NEUFELD:

Objection, your Honor. No foundation.

83 THE COURT:

Sustained.

84 MS. CLARK:

Have you ever taken off--have you ever had--

85 MR. NEUFELD:

Objection.

86 MS. CLARK:

Well, I don't know.

87 MS. CLARK:

Mr. MacDonell, have you ever had the experience of wearing nylon socks and exerting yourself to the point where you were sweating?

88 PROF. MACDONELL:

I used to wear work socks in the oil fields where I grew up and did a lot of manual labor, but I do not honestly remember ever sweating to the point where my socks got wet, and I didn't wear dress socks in the oil fields. I don't sweat when I wear dress socks. And if I can avoid it, I never wear them.

89 MS. CLARK:

Okay. So you've never had the experience yourself, sir, of ever sweating in dress socks?

90 PROF. MACDONELL:

Not that I can remember, no.

91 MS. CLARK:

Well, can I ask you, sir, if in your experience you have ever had occasion to note whether wet socks or sweaty feet made thin socks like this more difficult to remove? Do you have any experience in that?

92 MR. NEUFELD:

Objection. No foundation.

93 THE COURT:

She is asking for the foundation at this point. Do you wear these kind of socks?

94 PROF. MACDONELL:

No.

95 THE COURT:

Men have very particular preferences about their socks. Next question.

KEY QUOTE
96 MS. CLARK:

I'm sorry. All right. If someone has bloody hands, sir, and they attempt to take a sock off by maybe inserting the thumb, the thumbs inside and the fingers on the outside, if one or more of the fingers are bloody and pressing into the sock, will that cause a compression?

97 MR. NEUFELD:

Objection. Speculation at this point.

98 THE COURT:

Overruled.

99 PROF. MACDONELL:

Well, certainly. If you have bloody hands and touch any fabric, you can transfer blood to it.

100 MS. CLARK:

Okay. And if you were to touch--if there were wet blood on a piece of fabric that you pressed, that would cause a compression as well, correct?

101 PROF. MACDONELL:

If the blood was already on the fabric?

102 MS. CLARK:

Right, and it was wet.

103 PROF. MACDONELL:

You would squash the blood out of the fabric a little laterally, yes. It wouldn't cause a transfer unless it was in contact with something else. If you're transferring it to the thumb, yeah, you could transfer it from the fabric to the thumb, if that's what you mean.

104 MS. CLARK:

What I'm saying though, sir, is that if there's wet blood on a surface and you press it, will you cause a compression?

105 PROF. MACDONELL:

If you press it, you cause a compression, yes.

106 MS. CLARK:

And if wet blood is on a surface and you brush it, will that cause it to appear as a swipe?

107 PROF. MACDONELL:

Yes, it will. At that point, we would call a swipe pattern produced by a wiping action.

108 MS. CLARK:

And can you tell the difference, sir, between whether or not a blood drop has been dripped and swiped later? You know what I mean? Let me make that more clear. Can you tell the difference between whether or not a drop of blood is dripped onto a surface and while still wet, swiped between blood that is initially swiped on?

109 PROF. MACDONELL:

If there's enough blood to remain on the surface, it doesn't quickly soak right into the fiber of the fabric, you could laterally transfer it and cause a swipe pattern, yes.

110 MS. CLARK:

In which case, what you would detect would be a swipe pattern as opposed to a drip and a swipe?

111 PROF. MACDONELL:

I thought I was just answering the drip and swipe. You dripped it--first of all, you're talking about just a drop of blood on a fabric?

112 MS. CLARK:

Uh-huh.

113 PROF. MACDONELL:

If it falls on the fabric and you very quickly create a lateral motion, you should get a swiping of that blood which will leave blood on the top of the fibers, yes.

114 MS. CLARK:

And then when you come to analyze it, you would see a swipe and not a drip and a swipe? That was my question.

115 PROF. MACDONELL:

Yes. That's correct. You couldn't tell the difference if it was done quickly. That's correct.

116 MS. CLARK:

And the same would be true I take it for a compression; is that right?

117 PROF. MACDONELL:

Yes. If the blood is still fluid enough, you can get a lateral motion and it would look like a swipe.

118 MS. CLARK:

And likewise, sir, if it was with respect to a stain that you call a compression, if the blood was still fluid and then compressed with the hand or a finger, you would--then it would look like a compression to you; would it not?

119 PROF. MACDONELL:

Well, you just said if it was a compression. So it would look like a compression, yes.

120 MS. CLARK:

As opposed to a drip and then a subsequent compression?

121 PROF. MACDONELL:

I think that would be a very difficult thing to differentiate with any degree of accuracy.

122 MS. CLARK:

Okay. Now, you--all right. The--those little balls on surface 3, you do not know--those were not typed to determine whether they were blood, correct?

123 PROF. MACDONELL:

As far as I know, they never have been.

124 MS. CLARK:

And you don't know obviously then--

125 MR. NEUFELD:

Objection, your Honor. Ask for a sidebar.

126 MS. CLARK:

Assuming they are blood, sir, you don't know whose blood they are; is that correct?

127 PROF. MACDONELL:

That is correct.

128 MS. CLARK:

Now, you indicated that you saw--you determined--without ever having seen the actual piece of fabric cut out of the center of the stain, you gave us an estimate that the entire stain would have been 50 to 60 microliters of blood, assuming it was blood.

129 PROF. MACDONELL:

That's correct.

130 MS. CLARK:

Okay. And that what you saw on the opposite side in terms of the little flakes and the little balls, you never attempted to quantify; is that right?

131 PROF. MACDONELL:

Other than to say there was an extremely small volume, no.

132 MR. NEUFELD:

Objection. Asked three times.

133 THE COURT:

Actually this is the fourth time. You're right.

KEY QUOTE
134 MS. CLARK:

All right. So let me ask you a few questions about your background.

135 MS. CLARK:

Do we have to quit exactly at 4:00?

136 THE COURT:

Yes, we do. We have a doctor's appointment that we have to keep.

137 MS. CLARK:

Oh, that's right. That's right. That's right. All right. Would you like to break now, your Honor? I have one very short area I intend to complete tomorrow. I won't be able to complete it before 4:00 o'clock.

138 THE COURT:

Why don't you finish what you can.

139 MS. CLARK:

Okay.

140 MS. CLARK:

All right, sir. You stated that you were a professor of chemistry at Milton College in Wisconsin for a period of time?

141 PROF. MACDONELL:

Yes, I was.

142 MS. CLARK:

Yeah. Is that college now closed, sir?

143 PROF. MACDONELL:

Yes, it is.

144 MS. CLARK:

When it was opened, it was a small liberal arts college; is that right?

145 PROF. MACDONELL:

That's correct.

146 MS. CLARK:

About what? 350, 500 students?

147 PROF. MACDONELL:

Well, I don't think they ever had 500 while I was there. More like 250 to 300 I would think.

148 MS. CLARK:

Now, let me ask you, at the time that you became a professor, you had an undergraduate degree, correct?

149 PROF. MACDONELL:

That's correct.

150 MS. CLARK:

And you became the head of the department of chemistry at Milton College; is that right?

151 PROF. MACDONELL:

That's correct.

152 MS. CLARK:

Now, when you were head of the department, sir, the entire chemistry department consisted of who?

153 PROF. MACDONELL:

Me. I was it. I replaced two people and offered 12 courses.

KEY QUOTE
154 MS. CLARK:

Okay. Did you give yourself assignments?

155 PROF. MACDONELL:

I gave a lot of assignments.

156 MS. CLARK:

I mean as head of the department. That was a joke. All right. You taught criminalistics at El Myra College in New York?

157 PROF. MACDONELL:

Yes, I did.

158 MS. CLARK:

And you left there in 1983; is that right?

159 PROF. MACDONELL:

That's correct.

160 MS. CLARK:

Okay. You were you said adjunct. But that's a part-time professor; is that right?

161 PROF. MACDONELL:

Part-time, rank of full professor. I believe they had adjunct, associate adjunct, assistant. It varies from one school to another.

162 MS. CLARK:

Okay. So what--were you teaching at night, sir?

163 PROF. MACDONELL:

Yes, I was.

164 MS. CLARK:

Was that a continuing education course you were teaching?

165 PROF. MACDONELL:

Continuing education courses. I taught quite a few.

166 MS. CLARK:

Okay. Was that two to three days a week?

167 PROF. MACDONELL:

It depended. It was usually two nights a week and--yeah. It was two nights a week every semester in the summer.

168 MS. CLARK:

You taught one time at Corning College; is that right?

169 PROF. MACDONELL:

For quite some time. Corning Community College.

170 MS. CLARK:

Okay. Yeah. That's a two-year college; is that right, sir?

171 PROF. MACDONELL:

Yes.

172 MS. CLARK:

Though they don't give any degrees other than AA?

173 PROF. MACDONELL:

I'm not sure about that. I think they have, since I left, negotiated some form of getting a four-year degree or a masters program through John J. College in New York. I'm not sure about that. But basically it's a two-year school, part of the State University of New York.

174 MS. CLARK:

Okay. And, again, there you were teaching part-time?

175 PROF. MACDONELL:

Yes.

176 MS. CLARK:

And was it night school again, continuing education program?

177 PROF. MACDONELL:

It was days in the beginning in 1960 and then it went through different transitions and ultimately ended up in the evening program, yes.

178 MS. CLARK:

Okay. And was that, again, two to three nights a week?

179 PROF. MACDONELL:

It varied depending on the semester. But two nights a week was the most I could do.

180 MS. CLARK:

Now, with respect to either El Myra College or Corning, sir, would you say that either one of them had a formal forensic science program?

181 PROF. MACDONELL:

They did at the time. They had a criminal justice program at both places. Department of criminal justice I think is what they called it. They also had a forensic science certificate.

182 MS. CLARK:

Okay. But when I say a formal forensic science program, sir, I'm talking about something akin to formal program for the giving of a degree in criminalistics or forensic science.

183 PROF. MACDONELL:

They gave a degree with a major in criminal justice. I don't remember the exact title of it. That's what it was.

184 MS. CLARK:

But the criminal justice program is like the administration of justice, isn't it?

185 PROF. MACDONELL:

Well, that's part of it I guess, yes.

186 MS. CLARK:

It is not primarily a science program, is it?

187 PROF. MACDONELL:

No, but it satisfies certain science requirements or at least it did.

188 MS. CLARK:

It's primarily a course work--a study of course work that deals with the criminal justice system; isn't that right?

189 PROF. MACDONELL:

In general. But my work was primarily in the forensic area of physical evidence and crime scene investigation and microscopy and so on.

190 MS. CLARK:

Here, sir?

191 THE COURT:

Yep. Ladies and gentlemen, we are going to take our recess for the afternoon session. Please remember all of my admonitions to you; don't discuss the case amongst yourselves, form any opinions about the case, don't conduct any deliberations until the matter has been submitted to you, don't allow anybody to communicate with you with regard to the case. Take care of yourselves. Stay well. If there's anything we can do in that respect to help you out, let us know. All right. Get plenty of exercise, fresh air, see the doctor when you need to see the doctor. All right. As far as the jury is concerned, we'll stand in recess until 9:00 o'clock. After we clear the courtroom, we'll get Mr. Bosco's status report. And, professor, we'll see you tomorrow morning, 9:00 o'clock.

Key Quotes (5)

Prof. Herbert MacDonell
I am a scientist, not an advocate, and I am not changing, modifying or correcting anything for anyone's benefit except to clarify the matter to the jury. That's my purpose here.
MacDonell's most forceful self-defense against Clark's suggestion that he tailored his testimony to help Simpson; a signature moment of the examination.
Prof. Herbert MacDonell
Me. I was it. I replaced two people and offered 12 courses.
Devastating to his credibility as an academic — the 'chemistry department' he chaired consisted entirely of himself at a tiny college that has since closed.
Lance A. Ito
Men have very particular preferences about their socks. Next question.
Ito's dry aside after MacDonell admitted he never wears dress socks, cutting off a foundering line of questioning about sweaty feet.
Prof. Herbert MacDonell
Yes. They're the same thing. They're both compression transfers. One has a little more lateral motion than the other.
MacDonell concedes swipe and compression are not categorically different, undermining the significance of the terminology shift Clark was targeting.
Lance A. Ito
Actually this is the fourth time. You're right.
Ito agrees with Neufeld's objection that Clark has asked the same question about the unquantified bloodstain balls four times — a rare rebuke of the prosecutor.

Evidence (3)

People's 127

Clark systematically dismantled MacDonell's academic resume: his chemistry professorship was at a now-closed 250-student school where he was the entire department, and subsequent teaching was part-time night school at community colleges.
revealing

Light Moments (2)

Lance A. Ito
After MacDonell admitted he never wears dress socks and couldn't speak to sweaty-sock removal, Judge Ito cut off the line with: 'Men have very particular preferences about their socks. Next question.'
Prof. Herbert MacDonell
When Clark asked if MacDonell gave himself assignments as department head (a joke about being a one-man department), MacDonell deadpanned: 'I gave a lot of assignments.' Clark acknowledged: 'That was a joke.'

Credibility Attacks (2)

⚔ Prof. Herbert MacDonell
prior inconsistent statement / terminology shift
Clark documented that MacDonell's written report described the sock stain as a 'swipe' but he testified at trial it was a 'compression,' implying he adjusted his language to be more favorable to the defense.
⚔ Prof. Herbert MacDonell
impeachment of credentials
Clark established that MacDonell's academic positions were: (1) full professor at a now-defunct 250-student college where he was the entire chemistry department with only an undergrad degree; (2) part-time night adjunct at a community college; (3) part-time adjunct at a two-year school — significantly undermining his presentation as a senior academic authority.

Witness Demeanor

MacDonell was composed and combative when accused of advocacy, delivering his 'I am a scientist, not an advocate' line with apparent conviction.
MacDonell was matter-of-fact and unembarrassed about his one-man department, seemingly unaware of how damaging the admission sounded.
MacDonell acknowledged uncertainty about the sock photograph multiple times ('I honestly can't tell'), which was relatively candid for an expert witness.
