All right. Thank you, ladies and gentlemen. Please be seated. All right. Let the record reflect that we have been rejoined by all the members of our jury panel. Mr. Sims, would you resume the witness stand, please. All right. Mr. Harmon has completed his direct examination. And Mr. Scheck, you may commence your cross-examination.
Thank you, your Honor. Good morning, ladies and gentlemen of the jury.
THE JURY: Good morning.
CROSS-EXAMINATION BY MR. SCHECK
Mr. Sims, could you join me for a minute, and if we could look, just to clarify some of the facts here, at People's 172 and also the results board, People's 260, to understand precisely what you have done here. Now, first of all, items 30 and 31 are depicted in the upper right-hand corner; is that correct?
And each picture on this board, 29, that is the steering wheel you told us about, right?
And number--the next picture over, 33, another picture of the steering wheel, 29, 33 again, 22, 23, 34, the picture showing 25, 26, 27, all those pictures were of collections made on June 14th, 1994? That is your understanding, correct?
All right. Now, samples 303, 304 and 305, those are the samples that you combined to do your new RFLP test, right?
Okay. Now, the results you got on the Bronco samples that were collected on June 14th are shown in the result board here that is 30 and 31, correct?
Now, 30 is depicted in the upper right-hand corner from that swatch collected on June 14th, you got a 1.1, 1.2, 24, 25, correct?
And from that typing there is--you can exclude Ronald Goldman and Nicole Brown Simpson?
All right. Which is that one on the DQ-Alpha and D1S80, you got results that were consistent with Mr. Simpson, Mr. Goldman and Nicole Brown?
And in theory it is your understanding that 30 and 303 were taken from the same area?
Is it your understanding that 303 and 30 were supposed to be bloodstains in the same area?
I remember we went through all this in May and I think we got down to the issue of what is--what are we talking about when we are saying it is exactly the same area?
Thank you. Now, 31, okay, that is the second stain from the console from June 14th, right?
And that is the one that you say has a DNA--a DQ-Alpha profile that is consistent with Mr. Goldman?
All right. Now--your Honor, I'm--for the sake of--I don't know if it can be seen, so I will try to put it in the middle.
And my--you would agree when I asked you those questions on cross-examination the issues probably weren't so clear the way I did it that way with dots?
Oh, you thought it was clear? I apologize. But when dr. Gerdes testified he made points that were similar to precisely the points I made--was making with you when we visited this issue on cross-examination?
Now, you stated on direct examination one of the concerns that dr. Gerdes expressed with respect to this 1.3 dot, correct?
Now, wasn't one of the points that dr. Gerdes made is that there was also evidence of the 1.3 dot appearing on the quality sample 86 and the positive control on the same run?
Right. And he took the position that scientifically when your controls are showing 1.3's, that shouldn't be there, it is improper to call a 1.3 that is also faint within a mixture? You remember he made that point?
And your protocol, as we discussed when I cross-examined you, does say that if the quality control and the positive control fail or show unexpected results, that the procedure is to do it again?
That's what we would say, yes. In other words, if they show--I think the key word is whether or not they fail, but in my opinion, they didn't fail.
However, on item 52 on board 1310 there was a--what you in your terminology called a 1.3 trace, correct?
Right. And there is also on one of the quality assurance samples in this run what you called a trace of a 1.3?
Yes. I believe that is right, but I would like to quickly check the note sheet for that day.
Well, would you accept my representation that this came from the note sheet? Is that your--
Yes. In other words, there was more of a dot showing on this particular positive control than the previous one you showed me.
And if that 1.3 were a real allele, then that would indicate that there was perhaps more than one contributor to the stain you had?
And in your notes, even though it is not really visible on this strip, it was recorded very faint trace?
And would you agree that the amount of time that you develop them may relate to the intensity of the 1.3 dot?
Well, beyond--beyond about twenty minutes it was really very little difference in those. It is mainly what happens in the first twenty minutes that is the issue.
Well, you didn't indicate on the sheets how long the original run of item 52 was developed?
All right. Now, dr.--to finish this up, you recall that dr. Gerdes criticized your results by saying that it was inconsistent to call this 1.3 not real and without further testing to call the 1.3 on sample 31 real?
Okay. So those are some of the concerns that dr. Gerdes expressed with respect to a full rendition of his concerns with respect to sample 31. Fair statement?
Okay. And just so we are all clear, with respect to the console of the Bronco and the samples that were collected on June 14th, the only evidence of DNA testing that you had with respect to the console is that 1.3, 4 finding that you and dr. Gerdes disagree about on item 31?
Okay. Now, with respect to the results on 303, 304 and 305, you recall that dr. Gerdes expressed the view that the integrity of the evidence had been compromised by the way in which the Bronco was handled between June 14th and August 26th. Do you recall that?
Objection, that misstates the testimony. That is argumentative. That is not what he said. It is beyond the scope of the direct examination.
All right. So you recall that with respect to his opinions about 303, 304 and 305, that was a concern of his?
All right. And do you have some familiarity with the way the Bronco was handled between June 14th and August 26th.
Mr. Sims, from what you know about the way the chain of custody for the Bronco was handled, between June 14th and August 26th, do you think it was handled appropriately, in your forensic opinion?
Well, I don't--I don't know the whole history of how that Bronco was maintained. I don't know the whole history of that. I've heard that there were some--
I've heard that the Defense has raised some issues with regard to that. I don't know the truth of the matter on all these issues, though.
I heard him express concerns. I don't know what his basis for those concerns were, other than the general term "Chain of evidence."
Well, you have no knowledge with respect to whether or not this Bronco was secured for further biological analysis between August 26th and June 14th in a way that would preserve the integrity of the evidence? You have no knowledge of that?
Well, I--I know what I see in the newspaper and I know, for example, that I think two weeks ago I called a witness that addressed some of those issues, but that is what my knowledge is.
And you have not familiarized yourself then at all with what the history was of how the Bronco was kept? Is that what you are telling us?
Have you--let me try it this way: Mr. Sims, in your forensic opinion, based on your experience--
All right. Mr. Scheck, is it necessary for him to be down there at this point? Simply because the--we ought to use the microphones when we--
Mr. Sims, to try to cut to the heart of it quickly, let me--let me ask you to assume that between June 14th and August 26th the Bronco automobile was not--was put into a tow yard, that no records were kept as to who entered or left it between June 14th and August 26th, that unauthorized personnel were in and out of that Bronco automobile, that is non-police personnel, they were in the seats, they were looking around the car. Would you consider that an appropriate way to preserve the integrity of biological evidence?
Well, I--I don't think that should be allowed. I don't think one should be allowed to come in and out of a car. I think that should be done by authorized people.
And that records should be kept as to who has access and doesn't have access to the vehicle if you were going to preserve blood evidence for future biological testing?
Well, when you put it in the context of records should be kept, I don't know. I mean, for example, there may be, you know, other tow yards that I have been involved with in forensic cases where perhaps just one person has the keys, so there is no record kept of all those things, but that should be controlled. Access should be controlled.
Now--so basically you have no basis for disagreeing with dr. Gerdes' judgment that the integrity of those samples, 303, 304 and 305, was compromised by the chain of custody procedures used in this case?
All right. You heard his testimony that he believed as a scientist that the chain of custody for those samples compromised the integrity of future analysis? You recall that?
And you are saying to us that you are really not familiar with the details of how--of the chain of custody of the Bronco?
And you have not endeavored to become more familiar with the exact detail of how it was kept and who was in and out of the car?
And therefore you wouldn't want to render an opinion on it because you don't have enough information?
Well, I think I did offer the opinion of what should be done with that kind of evidence as far as securing it, yes.
All right. So your general opinion is that wasn't handled properly, but you don't know the specific detail of how bad it was.
Now, just so we are clear, what you have done since we last visited is that you combined the samples that were found on August 26th, 303, 304 and 305, and you put them together; is that correct?
Now, altogether, when you did the quantitations on all these stains combined, you came up with 72 nanograms of high-molecular weight DNA?
Well, there was actually more than that, I believe, after, but some other tests were run in between, but it is about 72 nanograms.
And the predominant contribution in the mixture is DNA that you say is consistent with Mr. Simpson?
Yes. I--I would say it is somewhere 3 to 1, maybe 2 to 1, but that is the right ballpark.
And therefore the amount of DNA on the RFLP tests that is consistent with the profile of Mr. Goldman would be something on the order of 20 nanograms of DNA?
And that is why you had to put these probes, keep those probes cooking, so to speak, for fifteen or sixteen days, to try to draw up the amount of DNA because there was comparatively a small amount there?
Yes. Technically what is going on is that there is a low amount of DNA on that membrane, that southern blot that we made, which means that there is a low amount of radioactive probe that is binding, and so you have to let the film that is--that is developing, you have to let that film go for a longer period of time. Usually we do these in a couple days, but for this type of sample you have to let it go a week or longer to get those weak bands to show up.
So 20 nanograms of DNA, that is really at the low end of your ability to detect, isn't it?
Now, if we were to look at--to give us some perspective, one drop of blood contains about 1000 nanograms of high-molecular weight DNA?
All right. And in fact you have seen estimates in the NRC report and other places that some people put it at between one and 2000?
Now, if you, based on your quantitations, were to combine the amount of DNA that you got as a whole in 305, 304, 303, the August 26th collections, and for just the purpose of this hypothetical, let's also include the amount of DNA that came out of the swatches from 30 and 31--are you with me?
--would you not agree that combining all of those together, all that from the console together, the amount of DNA would not exceed a hundred nanograms?
Well, you have to remember that with a drop of blood, for example, if you are testing liquid blood, that is not the same as extracting DNA out of a stain's worth of one drop of blood, so there is--you are not quite talking apples--you are somewhat talking apples and oranges there, but in terms of the ballpark you are talking about, you know, maybe getting three/quarters of that DNA out, so you can figure it from that.
All right. So what you are basically saying to us is that maybe if you are just dealing with a pristine drop of blood, you won't get a thousand nanograms, you will get 750?
Okay. And if we were to--I mean no disrespect for that, just summarizing it. And so if you've got about a hundred nanograms of DNA and there is 750 nanograms in a drop of blood, can you give me that fraction quickly? That would be, what, about a seventh?
Okay. So certainly, just reasoning from the DNA alone, the amount of blood, just looking at the DNA in the console, as you said, is in the area of a hundred nanograms of DNA?
Here is the problem. The moment I start to think about something else--proceed.
KEY QUOTEOkay. Now, you also were asked some questions on--withdrawn. I will start this way: Now, you don't know anything about the order in which blood was deposited on that console?
Are you familiar with the testimony of dr. Baden in this case that Mr. Simpson told him that he had cut himself on the evening of June 12th, I believe, and that he had gone into the Bronco searching for his cellular phone?
And with a small cut on the side of his finger and had blood within the Bronco? Are you familiar with that testimony.
No, I really wasn't interested in doctor, is it Baden how you say it, in his testimony. I don't recall that. I don't recall his testimony on that issue.
All right. Just look at it then from the point of view of forensic DNA expertise that you have, ask you to assume that there was an initial deposit of Mr. Simpson's blood on the Bronco from a small cut and I ask you further to assume that a--at a later point in time there was a second deposit, all right? Do you have that hypothetical?
And if one assumes, for the sake of argument and for the sake of this hypothetical, that the bloodstains of 303, 304, 305, all right, were all present also on June 14th, all right, asking you to assume both of these--there is no question, just for the purpose of this hypothetical--that everything that was on--on August 26th, all right, that was found there, was also present on June 14th, just for the purpose of this hypothetical. Are you with me?
Right. But if we assume that on August 26th the finding--the stains there 303, 304, 305, were also present on June 14th, but somehow they were missed, okay--
--your conclusions with respect to mixtures are not inconsistent with two deposits at two separate times?
Objection. That is an improper hypothetical. Misstates the testimony. There is no foundation.
Okay. I understand the hypothetical, but now give me the last phrase, please, the question.
In other words, your findings here of mixtures are not inconsistent with a contribution of Mr. Simpson's blood at one point in time and then a subsequent contribution of blood from Mr. Goldman at a subsequent point in time?
And in fact, based on all the testing that you did, most of the blood, if we--withdrawn. Most of the DNA that you extracted from that console is consistent with Mr. Simpson?
In the sample that we look at he would be consistent with the main contributor of that DNA mix.
Yes, that is--again, that is a reasonable figure, something like 3 to 1, maybe 2 to 1.
Now, finally, there--you have continued testing--are you still continuing testing in this case?
Well, as I mentioned, there is another autorad that we would--I would like to look at this afternoon, another probe or another one of these autorads that we are developing.
Have you tested item 1, the speck on the door that was first observed by Detective Fuhrman?
I think the key word is whether or not they fail, but in my opinion, they didn't fail.
I don't think one should be allowed to come in and out of a car. I think that should be done by authorized people.
So that is one/tenth of one drop of blood?
Here is the problem. The moment I start to think about something else--proceed.
That's correct. I'm not familiar with those details.
