Cross-examination of Gregory Matheson (part 4)

Witness: Gregory Matheson
Examiner: Robert Blasier
Called by: Prosecution • Date: Wednesday, May 3, 1995 • Utterances: 260
Defense attorney Robert Blasier cross-examines LAPD criminalist Gregory Matheson about systemic failures in the handling of physical evidence, focusing on three main areas: the incomplete initial search of the Bronco (which left blood behind), the presence of blood on the outside of victim reference vials, and a pheno test performed by Dennis Fung on the Bronco in July that went undocumented for months. Matheson repeatedly acknowledges he lacked knowledge of key events and trusted subordinates whose work is now being challenged.
1 (Discussion held off the record between Defense counsel.)
2 MR. BLASIER:

When would these reports be copied and distributed? How long after a particular search took place, in general?

3 MR. MATHESON:

Are we talking about in relation to this case or in other cases?

4 MR. BLASIER:

This case. This case.

5 MR. MATHESON:

Well, as a rule, given some of the conditions, that we were trying to get things turned over as soon as possible. I don't know. It would depend. I mean, sometimes we were not receiving some of this information until a significantly later time.

6 MR. BLASIER:

At some point did you become aware of the possible significance of four small stains on the door or the door sill of the Bronco?

7 MR. GOLDBERG:

No foundation for personal knowledge; calls for hearsay.

8 THE COURT:

Overruled.

9 MR. MATHESON:

The first time I specifically remember hearing about those was in testimony on this case.

10 MR. BLASIER:

So you are not aware at any time prior to that that there was any concern about whether those stains existed or not?

11 MR. GOLDBERG:

Your Honor, this is argumentative.

12 THE COURT:

Sustained.

13 (Discussion held off the record between Defense counsel.)
14 MR. BLASIER:

When you say the testimony in this case is where you became aware of that, was that Detective Fuhrman's testimony at the preliminary hearing?

15 MR. MATHESON:

No, it was Mr. Fung's during the trial.

16 MR. BLASIER:

You had no awareness of Mr. Fung being sent out by the District Attorney's office to look at that Bronco on July 6th?

17 MR. GOLDBERG:

Not relevant.

18 THE COURT:

Overruled.

19 MR. MATHESON:

Not as I recall, no.

20 MR. BLASIER:

Were you still supervising him at that time?

21 MR. GOLDBERG:

Assumes facts not in evidence.

22 THE COURT:

Sustained.

23 MR. BLASIER:

Were you still in charge of managing the items in this case at that time?

24 MR. MATHESON:

It was one of my tasks to be involved in tracking the items, yes.

25 MR. BLASIER:

Would you agree that it is proper procedure for a criminalist collecting an individual stain to collect the whole stain, if possible?

26 MR. MATHESON:

If possible. If it is not--if it is a very, very large stain, there is no reason to, but if it is a small stain I would expect it to be collected.

27 MR. BLASIER:

If it is a manageable size stain, they should collect all of it, correct?

28 MR. MATHESON:

As much as possible, yes.

29 MR. BLASIER:

And the reason for that is you can't tell from looking at a stain how good the mood or whatever it happens to be is going to be in terms of your being able to extract any information from it?

30 MR. MATHESON:

That's correct.

31 MR. BLASIER:

So you try to get as much as you can, correct?

32 MR. MATHESON:

That's correct.

33 MR. BLASIER:

And your people understand that?

34 MR. MATHESON:

I believe so, yes.

35 MR. BLASIER:

Now, when Dennis Fung and Andrea Mazzola searched the Bronco on the 14th, did you discuss, after they were done with that, anything about that search?

36 MR. MATHESON:

I may have gotten a general overview of what was collected, but not in detail, no.

37 MR. BLASIER:

Did Dennis Fung ever tell you after the 14th that he had left a lot of blood in the Bronco?

38 MR. GOLDBERG:

Calls for hearsay, argumentative.

39 THE COURT:

Sustained.

40 MR. BLASIER:

Did you become aware at any time--let me rephrase that. Did you have any awareness at all, after the 14th, that blood--let me rephrase. When did you first become aware that there was more blood in the Bronco after the 14th?

41 MR. MATHESON:

That was when I saw the console when it was in the serology laboratory.

KEY QUOTE
42 MR. BLASIER:

So nobody had informed you of that fact prior to that time?

43 MR. MATHESON:

It is possible that it was mentioned to me. I believe the search and the collection of the item from the Bronco was on August 26th. It is possible at that point that Miss Kestler mentioned to me there was blood present. I did not see any of these items, though, until they were back into the laboratory.

44 MR. BLASIER:

Now, you indicated earlier that it is your practice or the lab's practice, for continuity, to have the same criminalist stay with a case throughout the case, if possible?

45 MR. MATHESON:

If possible we try to.

46 MR. BLASIER:

Now, when did Andrea Mazzola stop working on this case in terms of doing searches?

47 MR. MATHESON:

I believe it was following the Bronco search in the shed, but I'm not quite sure.

48 MR. BLASIER:

On the 14th?

49 MR. MATHESON:

I believe so.

50 MR. BLASIER:

Was she available after the 14th?

51 MR. MATHESON:

She was working, yes.

52 MR. BLASIER:

Was she available to do further searches on this case?

53 MR. MATHESON:

I don't know. She works not in one of my units. I wouldn't know on any particular date and time if she was available.

54 MR. BLASIER:

For continuity of the case isn't it your practice that she should have stayed on the case?

55 MR. GOLDBERG:

Asked and answered.

56 THE COURT:

Overruled.

57 MR. MATHESON:

In--all of this leaves us with the ability to make changes. In other words, in a normal case where we have a crime scene search and then maybe a follow-up scene of one type and that is it, we try and maintain this continuity. However, given the extent and the complexity of this case, at one point we decided to start involving other people besides the original two.

58 MR. BLASIER:

And was she taken off because of her lack of experience?

59 MR. GOLDBERG:

Assumes facts not in evidence.

60 THE COURT:

Sustained.

61 MR. BLASIER:

Why did she not do any further searches in this case?

62 MR. MATHESON:

Because she had duties in her own unit and she was done at that point with this particular situation. We were bringing other people in that potentially would be being involved with the analysis of the evidence farther down the road.

63 MR. BLASIER:

Now, the search that was done on August 26th, that was done by Michele Kestler, the head of the lab, correct?

64 MR. MATHESON:

She was one of the parties there, yes.

65 MR. BLASIER:

And the media was invited to that search, correct?

66 MR. MATHESON:

I believe there was a photographer.

67 MR. BLASIER:

Dennis Fung wasn't invited to that search, was he?

68 MR. MATHESON:

I don't know if he was invited or not.

69 (Discussion held off the record between Defense counsel.)
70 MR. BLASIER:

A photographer from life magazine was invited to that search, correct?

71 MR. GOLDBERG:

Not relevant.

72 THE COURT:

Sustained.

73 MR. BLASIER:

What level of security, to your knowledge, had been provided to--for the Bronco during the period of time from June 14th until August 24th?

74 MR. GOLDBERG:

No foundation, personal knowledge.

75 THE COURT:

Sustained. Reask the question.

76 MR. BLASIER:

Do you have any personal knowledge about what security there was surrounding the Bronco between June 14th and August 24th or 26th when that search took place?

77 MR. MATHESON:

No specific knowledge, no.

78 (Discussion held off the record between Defense counsel.)
79 MR. BLASIER:

Now, is there a policy with respect to vehicles in terms of processing them quickly because they are mobile to a certain extent?

80 MR. MATHESON:

I don't know if the reason to process them quickly has to do with any sort of mobility. It would be imperative or important to process any sort of scene quickly, of which a vehicle is one, to attempt to recover any biological evidence that my degrade.

81 MR. BLASIER:

Now, vehicles are not stored in the evidence control unit, are they?

82 MR. MATHESON:

No, they are not.

83 MR. BLASIER:

They are stored at a tow yard, aren't they?

84 MR. GOLDBERG:

Vague as to time.

85 THE COURT:

Overruled.

86 MR. MATHESON:

There are two different ways that a vehicle can be brought into the possession of our department and stored. One of them is we have a facility where--which is under the control of the police department located behind Parker Center where we have temporary storage of vehicles and it is an area where they can be searched. At some point then they are transferred out to an official police garage or in some cases they go directly to the police garage.

87 MR. BLASIER:

Directly to, I'm sorry?

88 MR. MATHESON:

The police garage, an official tow yard.

89 MR. BLASIER:

This Bronco was moved to a tow yard, was it not?

90 MR. GOLDBERG:

No foundation of personal knowledge. Beyond the scope.

91 THE COURT:

Sustained.

92 MR. BLASIER:

When it was searched on the 26th, where was that?

93 MR. MATHESON:

I don't know about on the 26th. I can make an assumption, but I don't know for a fact.

94 MR. BLASIER:

Is it important to process a vehicle, as a general rule, before it is put in a place where there is ready access by civilians?

95 MR. GOLDBERG:

Beyond the scope.

96 THE COURT:

Overruled.

97 MR. MATHESON:

Well, it is important to perform--it is important to perform any search, if you can, before it has--has the potential of access by anybody that doesn't belong there.

98 MR. BLASIER:

What steps did you take to see that the Bronco was thoroughly and carefully searched before it went to a tow yard, if any?

99 MR. GOLDBERG:

Beyond the scope, irrelevant.

100 THE COURT:

Overruled.

101 MR. MATHESON:

My understanding was that a search of that vehicle had been performed, I believe it was on the 14th or the 15th of June, and at that point that we were done with it.

102 MR. BLASIER:

So your impression was that everything of evidentiary value had been collected?

103 MR. MATHESON:

I trusted the criminalist we had at the scene to make that decision, yes.

KEY QUOTE
104 MR. BLASIER:

And that is the way they should have done it, correct?

105 MR. GOLDBERG:

Argumentative.

106 THE COURT:

Sustained.

107 MR. BLASIER:

Is that the proper way to do it?

108 MR. GOLDBERG:

Argumentative.

109 THE COURT:

Overruled.

110 MR. MATHESON:

Is what the proper way to do it?

111 MR. BLASIER:

When you go to search the vehicle to do it all at one time if you can, be thorough and get all the evidence that is there so you don't have to go back. Of course the best thing to do is get it all the first time.

112 MR. BLASIER:

And it is not desirable to have to go back a second time to a vehicle or any place to collect evidence that you missed the first time, is it?

113 MR. GOLDBERG:

It is vague as to "desirable."

114 THE COURT:

Overruled.

115 MR. MATHESON:

If you can avoid it, sure, it would be nice to get everything the first time every time. Occasionally, though, we do have to do repeats.

116 (Discussion held off the record between Defense counsel.)
117 MR. BLASIER:

Your Honor, I would like to show the witness a form.

118 (Discussion held off the record between the Deputy District Attorneys.)
119 THE COURT:

All right. Mr. Blasier.

120 MR. BLASIER:

Mr. Matheson, do you know what the term "special care" means with respect to a vehicle that has been seized?

121 MR. MATHESON:

Not that specific term, no.

122 MR. BLASIER:

Are you aware of any procedure that LAPD has in effect to provide special care to vehicles that have been seized?

123 MR. GOLDBERG:

No foundation for this witness' knowledge.

124 THE COURT:

Overruled.

125 MR. MATHESON:

Well, I do know--excuse me. I do know that the garages that the police department uses to store vehicles have areas that are designated as print sheds or what are supposed to be more secure areas than just their lot, so that they are maintained until our arrival for searching.

126 (Discussion held off the record between Defense counsel.)
127 MR. BLASIER:

Let me show you this form again and ask you if you are familiar with it. I wasn't sure I gave you a chance to look at it.

128 MR. GOLDBERG:

I would object to showing the witness the form. It is nothing that he created.

129 THE COURT:

Overruled. Do you recognize the form?

130 MR. MATHESON:

I recognize it by its title as being a Los Angeles Police Department vehicle investigation form. I have never utilized one of these.

131 THE COURT:

All right. Do you recognize the information? Are you familiar with the information that is on that form?

132 MR. MATHESON:

Information regarding the form itself or what it is filled out?

133 THE COURT:

The information that is contained on the form that has been filled in, are you familiar with that information?

134 MR. MATHESON:

Well, I recognize notations regarding this case and the--

135 THE COURT:

All right. Thank you. Mr. Blasier.

136 MR. BLASIER:

Are you familiar with the procedure that the Los Angeles Police Department uses to release a vehicle that they are done with?

137 MR. MATHESON:

No, I am not.

138 (Discussion held off the record between Defense counsel.)
139 MR. BLASIER:

I have a couple of pictures I would like to have marked.

140 THE COURT:

All right. 1128 and 1129.

141 (Deft's 1128 for id = photograph)
142 (Deft's 1129 for id = photograph)
143 MR. BLASIER:

Actually I have four, your Honor.

144 THE COURT:

1130 and 1131.

145 (Deft's 1130 for id = photograph)
146 (Deft's 1131 for id = photograph)
147 (Discussion held off the record between Deputy District Attorney and Defense counsel.)
148 MR. BLASIER:

I'm sorry, what was that first number, your Honor?

149 THE COURT:

1128.

150 (Brief pause.)
151 MR. GOLDBERG:

Were those marked a through--

152 THE COURT:

1128, 1129, 1130 and 1131.

153 (Brief pause.)
154 THE COURT:

And generally what are these, Mr. Blasier?

155 MR. BLASIER:

These are pictures of reference blood vials for both victims.

156 THE COURT:

All right.

157 MR. BLASIER:

Mr. Matheson, let me show you first 1128 and ask you if you recognize the blood vial in that picture?

158 MR. MATHESON:

Yes, I do.

159 MR. BLASIER:

And let me show you 1129 and see if you recognize that?

160 MR. MATHESON:

I believe it is the same one.

161 MR. BLASIER:

And what are those pictures of?

162 MR. MATHESON:

Of item no. 60 which I believe is Mr. Goldman's reference blood.

163 MR. BLASIER:

Let me show you 1130 and 1131. Do you recognize those and what are they?

164 MR. MATHESON:

These are both photographs of two sides of item no. 59 which I believe is Miss Brown's reference samples.

165 MR. BLASIER:

May I show these on the elmo, your Honor?

166 (Brief pause.)
167 MR. BLASIER:

Let me show first 1128 and 1129.

168 (Brief pause.)
169 MR. BLASIER:

Mr. Matheson, do those two pictures appear to be accurate pictures of the reference blood vial for Ronald Goldman?

170 MR. MATHESON:

Yes, they do.

171 MR. BLASIER:

Now, reference blood from victims is taken by the Coroners, correct?

172 MR. MATHESON:

That's correct.

173 MR. BLASIER:

That is not a function of SID, correct?

174 MR. MATHESON:

That's correct.

175 MR. BLASIER:

And after it is taken at the Coroner's office it is transported in some fashion to SID, correct?

176 MR. MATHESON:

Yes.

177 MR. BLASIER:

Now, you will agree that there is blood on the outside of that vial, would you?

178 MR. MATHESON:

Yes, there is.

179 MR. BLASIER:

There is a substantial amount of blood on the outside, isn't there?

180 MR. MATHESON:

Yes.

181 MR. BLASIER:

Do you know how that blood got on the outside of that vial?

182 MR. MATHESON:

Not specifically, no.

183 MR. BLASIER:

When blood gets outside of a vial would you agree that it is more likely that it can contaminate things?

184 MR. MATHESON:

Something comes in contact with it, sure.

185 MR. BLASIER:

And like a hand would come in contact, you could have some transfer of a small amount of blood from the blood to the hand, correct?

186 MR. MATHESON:

That's correct. That is why I would wear gloves if I was to handle this item.

KEY QUOTE
187 MR. BLASIER:

A small amount of blood that you might not be able to see?

188 MR. MATHESON:

That's correct.

189 MR. BLASIER:

But there would be enough blood to test and get a result on using DNA testing, correct?

190 MR. GOLDBERG:

Vague as to under what conditions.

191 THE COURT:

Sustained.

192 MR. BLASIER:

Are you aware of how much--well, let me withdraw that. Let's take a look at 1130 and 1131. 1130 and 1131, those are pictures of Nicole Brown Simpson's reference vial, correct?

193 MR. MATHESON:

Yes, it is.

194 MR. BLASIER:

And that would have been taken from the--originally taken from the Coroner's office, correct?

195 MR. MATHESON:

Yes.

196 MR. BLASIER:

Would you agree that there is blood also on the outside of that vial?

197 MR. MATHESON:

Yes.

198 MR. BLASIER:

Do you know how the blood got on the outside of the vial?

199 MR. MATHESON:

No, I have no personal knowledge of that.

200 MR. BLASIER:

When you use these vials to perform tests on them, do you pour blood out or do you use something like a pipette to take blood out?

201 MR. MATHESON:

You take it out with a pipetter.

202 MR. BLASIER:

You don't take it out in a fashion that would cause it to spill on the outside of the container, do you?

203 MR. MATHESON:

Try not to.

204 MR. BLASIER:

And to your knowledge does the Coroner follow the same procedure if they need to take a withdrawal, they use pipetters as well?

205 MR. MATHESON:

I don't know the procedures that they use.

206 (Brief pause.)
207 MR. BLASIER:

When are criminalists supposed to write reports of testing that they do with respect to when they do the test?

208 MR. MATHESON:

The final report?

209 MR. BLASIER:

Any report or notes?

210 MR. MATHESON:

Well, the notes, some of them are going to be completed as the work is done. At some point after that, upon the completion of the analysis, the notes or the summary is going to be brought together to make the report.

211 MR. BLASIER:

Is it acceptable procedure within your department for a criminalist to perform a test in July and not make any record of it until October?

212 MR. MATHESON:

That would be unique.

KEY QUOTE
213 MR. BLASIER:

That would be bad, wouldn't it?

214 MR. GOLDBERG:

Well, argumentative as to "bad."

215 THE COURT:

Sustained. Rephrase the question.

216 MR. BLASIER:

That would be unacceptable, wouldn't it?

217 MR. MATHESON:

I would want to know why that much time past.

218 MR. BLASIER:

You are aware that that happened with respect to a test that Dennis Fung did on the Bronco on July 6th, are you not?

219 MR. GOLDBERG:

Argumentative.

220 THE COURT:

Overruled.

221 MR. GOLDBERG:

It is also vague.

222 THE COURT:

Overruled.

223 MR. MATHESON:

I know that there was some information that was provided in a report at a later date. I don't specifically know which one you are talking about right now.

224 MR. BLASIER:

What effort did you make to find out about it, like you said you would?

225 MR. GOLDBERG:

Well, assumes facts not in evidence, also beyond the scope.

226 THE COURT:

Overruled.

227 MR. MATHESON:

Do you mean to find out why it had taken that long?

228 MR. BLASIER:

Yes.

229 MR. MATHESON:

Well, if I received a report after that amount of time, I would just ask him why it took so long to get the information down on a report.

230 MR. BLASIER:

What did you find out when you made that inquiry this time?

231 MR. GOLDBERG:

Assumes facts not in evidence.

232 THE COURT:

Sustained.

233 MR. BLASIER:

If you made an inquiry?

234 MR. GOLDBERG:

Well, it is an improper hypothetical.

235 THE COURT:

It is not a hypothetical. Did you make such an inquiry with regard to this report?

236 MR. MATHESON:

I am not specifically remembering which report we are talking about.

237 MR. BLASIER:

Well, let me make it more specific. A pheno test on purported or alleged stains on the bottom of the Bronco door?

238 MR. MATHESON:

Would it be possible for me to review that report?

239 (Discussion held off the record between Defense counsel.)
240 THE COURT:

Mr. Blasier, why don't we move on to something else and we will find that later.

241 MR. BLASIER:

Okay.

242 MR. BLASIER:

Is it proper procedure, when you do a pheno test on something such as a car, to photograph it before you do the test?

243 MR. MATHESON:

Sometimes we do and sometimes we don't. As an explanation for that is if I see a stain and I don't know whether or not it is blood, I normally will not photograph it first because if it is not blood, if it is not something of interest, then it won't be collected, and thus it is not evidence, there is no reason to have a photograph of it. If I--it is something that I know I'm going to be collecting, there is a very good chance I would have it photographed before performing the pheno test on it.

244 MR. BLASIER:

What if it is something that you suspect you are going to be collecting and that is why you run a test on it to begin with?

245 MR. GOLDBERG:

Improper hypothetical.

246 THE COURT:

Overruled.

247 MR. BLASIER:

Shouldn't you take a picture first?

248 MR. GOLDBERG:

It is not relevant.

249 THE COURT:

Overruled.

250 MR. MATHESON:

If it is something that I suspect that I'm going to be collecting? Because we do a lot of spot tests out in the field. In--well, if I found a blood stain or a stain that I suspected of being blood, and many times you can tell just by looking that it is probably blood, again it depends on the situation. If it is a very small sample and then I was going to be consuming a large portion of it, first off, I wouldn't want to necessarily run a pheno, but if I felt it was necessary, it would be a good idea to document first. If it is a larger sample, larger item and by removing a small portion and running my test is not going to make any significant alteration to it, then no, I wouldn't necessarily do it; I might.

251 MR. BLASIER:

Well, let me give you a more detailed hypothetical. Suppose a Prosecutor sends you out to look at something because a detective said there is blood there, go out, look at it and see if it is blood, come back and tell me. Would you document that by way of taking a photograph.

252 MR. GOLDBERG:

Improper hypothetical, calls for speculation.

253 THE COURT:

Sustained.

254 MR. BLASIER:

Is it proper to do a pheno test on an item and take a picture after you do the test while the stain is still moist from the pheno test?

255 MR. GOLDBERG:

Not relevant.

256 THE COURT:

Overruled.

257 MR. MATHESON:

I don't see any problem with it being moist from the test. As I mentioned before, I laid out the reasons or the times where I would have a photograph taken and that is if I ran--let's say I had a stain that I didn't know whether or not it was blood and I ran my pheno test on it and it turned out that it was blood and had it photographed. At that point I wouldn't worry whether or not it was damp from the testing.

258 MR. BLASIER:

Well, adding that moisture changes the appearance of it, does it not?

259 MR. MATHESON:

It depends on the size of the stain. If you are just testing a small corner, yes, it does, it makes a minor alteration.

260 THE COURT:

Mr. Blasier, I have to interrupt at this point. Remember all my admonitions to you. If you will just step back in the jury room. Don't go too far.

Key Quotes (5)

Gregory Matheson
I trusted the criminalist we had at the scene to make that decision, yes.
Matheson admits he simply deferred to Fung's judgment that the Bronco had been fully searched, setting up the defense argument that the missed blood was due to negligence.
Gregory Matheson
That was when I saw the console when it was in the serology laboratory.
The supervisor of the case did not learn that blood had been left behind in the Bronco until the console was retrieved weeks later — undercutting any claim of tight oversight.
Gregory Matheson
That would be unique.
Matheson's careful, bureaucratic answer when asked whether it was acceptable to perform a test in July and not document it until October — Blasier immediately follows up pressing him to call it 'unacceptable.'
Gregory Matheson
Yes, there is [a substantial amount of blood on the outside of that vial].
Matheson concedes that both victim reference vials had unexplained blood on their exteriors, supporting the defense theory of potential cross-contamination.
Gregory Matheson
That's correct. That is why I would wear gloves if I was to handle this item.
While explaining proper handling, Matheson implicitly confirms that blood on the outside of a vial can transfer to hands or other surfaces — a contamination vector the defense was building toward.

Notable Exchanges (4)

Robert BlasierGregory Matheson
Blasier establishes that Matheson had no knowledge blood remained in the Bronco after the June 14 search until he personally saw the console in the serology lab weeks later — meaning no one in the supervisory chain flagged it.

Robert BlasierGregory Matheson
Blasier displays photographs of both victim reference vials with visible blood on their exteriors and walks Matheson through the contamination chain: blood on outside of vial → hand contact → invisible transfer → enough for DNA testing. Matheson confirms each step.

Robert BlasierGregory MathesonHank Goldberg
Blasier asks whether it is 'bad' for a criminalist to perform a test in July and not document it until October. Goldberg objects to 'bad' as argumentative; Ito sustains. Blasier rephrases to 'unacceptable' and Matheson hedges: 'I would want to know why that much time past.'

Blasier reveals that a Life magazine photographer was invited to the August 26 Bronco re-search while Dennis Fung — the original criminalist — was not. Goldberg objects on relevance grounds and Ito sustains, cutting off the line.

Credibility Attacks (3)

⚔ Dennis Fung
prior bad acts / professional negligence
Blasier uses Matheson's supervisory role to establish that Fung left blood behind in the Bronco, ran a pheno test in July without documenting it until October, and was not invited back for the August 26 re-search — all through the testimony of his own supervisor.
⚔ LAPD SID (lab procedures generally)
established failure to follow stated policy
Blasier gets Matheson to articulate proper procedure at every step — collect everything at once, document promptly, maintain chain of custody — then demonstrates each standard was violated in this case, without Matheson being able to explain why.
⚔ Gregory Matheson
lack of supervisory knowledge
Matheson repeatedly admits he was unaware of key events in a case he was managing: the blood left in the Bronco, the July pheno test, whether Fung was sent out by the DA, and the security arrangements for the Bronco.

Witness Demeanor

Measured and careful — consistently hedging with 'I believe,' 'I don't specifically recall,' and 'It is possible.'
Matheson at one point asks to review the report being discussed before answering, suggesting discomfort with the specifics.
No stage directions indicating emotion or physical reaction.
