393 lines(In open court:)
BY MR. FICK:
MR. FICK: So, Agent Swindon, I'd like to talk a little bit now about how one traces the history of when a USB device was attached to a computer, okay?
KEVIN SWINDON: Okay.
MR. FICK: Okay? So you've heard of something called SetupAPI is a registry artifact in Windows. You're aware of that?
KEVIN SWINDON: I have to look at the registry report, but I believe it is one of the categories in a registry report, yes.
MR. FICK: Right. And that captures information about when a USB memory device is plugged into a computer for the first time, correct?
KEVIN SWINDON: I'm not sure what the chronological of events are, but I do know there is information stored there, yes.
KEVIN SWINDON: I would have to test that. I don't have that information in front of me.
MR. FICK: Well, I'm not talking about a specific computer, I'm talking about the methodology of doing the investigation now, okay? So as a general matter, SetupAPI contains date and time information about when a device is first plugged into a computer, correct?
KEVIN SWINDON: You have to pull that up so I can see a registry report to see what you're referring to.
KEVIN SWINDON: I'm familiar with it. It's an entry in the USB report that comes from the registry, yes.
KEVIN SWINDON: It records when it is attached. I'd have to see the report to know that that is the first time that was in that.
MR. FICK: The registry, apart from SetupAPI, also contains other information about incident -- incidents when a USB is attached, correct?
KEVIN SWINDON: Yes, it does.
MR. FICK: Okay. Now, these two sources I've mentioned, the SetupAPI and other data in the registry, actually record the event of the attachment, right?
KEVIN SWINDON: It would be the physical attachment or the physical putting of the USB drive into that particular machine.
MR. FICK: And in addition to those pieces of data, there's -- there are also artifacts called shortcuts and links that I think you testified about with Mr. Chakravarty, right?
KEVIN SWINDON: Yes.
MR. FICK: Okay. And shortcuts and links and jump lists contain information about files that a user may have accessed on a USB device, right?
KEVIN SWINDON: Among other things, but yes.
MR. FICK: Okay. So those record information about the files themselves, not the event of the USB connecting, correct?
KEVIN SWINDON: It could be the same event. But, yes, it does capture the file information.
MR. FICK: So in other words, you might be able to infer something about when a USB was attached from the jump list or link information but that's -- the jump list or link information itself records information about the file on the USB storage device, right?
KEVIN SWINDON: Right. So just for clarification, the registry contains the information about the hardware and the connection of when that piece of hardware went into that particular computer as opposed to the link file is going to have information regarding a file or files or folder that was accessed on that removable drive.
KEVIN SWINDON: Yes.
MR. FICK: Okay. So I'm going to pull up Exhibit 1142-02 which is the exhibit called "External Device Access on the Sony." You remember this spreadsheet that you talked about with Mr. Chakravarty, right?
KEVIN SWINDON: I do, yes.
MR. FICK: Okay. And this spreadsheet is based on jump list and shortcut data about files that were viewed on the Sony that were located on external devices, correct?
KEVIN SWINDON: These are the information from the jump list records that existed on the computer, yes.
KEVIN SWINDON: Yes.
KEVIN SWINDON: It includes some of the same information but it is not the registry report.
MR. FICK: It's not the registry report about the event of the device attachment, it's information about the files that were viewed on the external devices?
KEVIN SWINDON: Yes.
MR. FICK: Okay. Now, the creation date for each of these entries is the date the file was created on the external device, correct, because these are jump lists and links, right?
KEVIN SWINDON: I believe this might be the creation date of the actual link file. Let's see. 1B shortcut.
KEVIN SWINDON: Can you give me a minute because this is the only -- this is a -- a derivative report does not include all the information. So I would need to see the file, the information about the file, and then also the information about the Kingston thumb drive and the registry to determine that.
MR. FICK: Well, this is a spreadsheet that you reviewed and deemed to be accurate enough to include in an exhibit, correct?
KEVIN SWINDON: Yes.
KEVIN SWINDON: I would need the other two pieces of information that we verified this with to determine that.
KEVIN SWINDON: We verified hundreds of pieces of information on various spreadsheets.
MR. FICK: Okay. So sitting here you cannot tell me, then, whether this is the creation date of the file on the thumb drive or whether it's the date the thumb drive was inserted in the computer?
KEVIN SWINDON: Not without the supporting information.
KEVIN SWINDON: Not without the supporting information.
MR. FICK: Okay. Now, this Patriot thumb drive here, I believe you talked about that with Mr. Chakravarty, the serial number reflected there, that's not the same as the Patriot thumb drive that was recovered in the investigation and was included as an exhibit, correct?
KEVIN SWINDON: This is the -- you're talking about the volume serial number?
KEVIN SWINDON: Yes, that is not the Patriot that was --
MR. FICK: And, in fact, this Patriot thumb drive with this volume serial number was never recovered in the investigation, was it?
KEVIN SWINDON: I don't have it, no.
KEVIN SWINDON: I'm not aware of it being recovered.
MR. FICK: Now, do you know whether the FBI ever traced the artifacts from this missing Patriot across all of the electronic devices in the case?
KEVIN SWINDON: I'm not sure I understand the question.
MR. FICK: Well, for example, what we have here on this chart reflected in the first line is a data artifact taken from the Sony about this particular Patriot thumb drive at a particular point in time, right?
KEVIN SWINDON: Yes.
MR. FICK: At some point in time, it was attached to the Sony and this file on the Patriot thumb drive was viewed from the Sony, right?
KEVIN SWINDON: Yes.
MR. FICK: Okay. Now, did the FBI, to your knowledge, do any investigation of whether this Patriot thumb drive, the missing Patriot, was attached to other devices seized in the case?
KEVIN SWINDON: I believe that there was an analysis done on that, yes.
KEVIN SWINDON: I don't have access to that report.
KEVIN SWINDON: Or a report. I don't know.
MR. FICK: Now, another one of the devices you talked about was the Hewlett Packard desktop computer seized from 410 Norfolk Street, the Tsarnaev family apartment. You remember that?
KEVIN SWINDON: If you could bring it up to reference it, yes.
MR. FICK: Of course. I'm bringing back up 1557. The second line here, 2R14, HP Pavilion, 410 Norfolk, that's a desktop computer seized from 410 Norfolk Street, the Tsarnaev family apartment in Cambridge, correct?
KEVIN SWINDON: It was seized from 410 Norfolk, yes.
MR. FICK: Okay. And I think you testified on direct with Mr. Chakravarty last week that you acknowledge -- the FBI acknowledges that that computer was used by many people, right?
KEVIN SWINDON: I believe people -- yeah, many people had access to that computer, yes.
MR. FICK: A large number of Tsarnaev family members at various times lived in that apartment, right?
KEVIN SWINDON: I don't know. "Large" isn't a number. I'm not sure that we were able to determine how many, whether small or large, who had access to that computer.
KEVIN SWINDON: Yes.
KEVIN SWINDON: Only from the computer username.
KEVIN SWINDON: I don't. I don't.
KEVIN SWINDON: I didn't have anything to do with his parents in this investigation.
MR. FICK: So you know a number of people had access to the computer at 410 Norfolk Street, this computer, but you don't know who that might have been?
KEVIN SWINDON: Not from the information in front of me, I can't determine that, no.
MR. FICK: Well, apart from the information in front of you, from your knowledge of the investigation, being a supervisor of the CART team for two years -- for the last two years, do you know anything about that?
KEVIN SWINDON: Well, there are a number of pieces of information we would use to determine access to a computer. We would use the username that's associated with the computer. There would also be pattern-of-life investigative information that we would use. And then there would be email access, Skype access and different types of maybe social media or access that we would be able to determine who was using that computer.
MR. FICK: And when you say "pattern-of-life information," that's information developed from the investigation about people who may have had access to the computer, right?
KEVIN SWINDON: It's more -- not specifically the computer but pattern of life would be when somebody comes and goes either for work or for school or --
MR. FICK: And your testimony was you do know that multiple people had access to this computer, right?
KEVIN SWINDON: Yes.
KEVIN SWINDON: I can't specifically tell you who specifically had access to that computer.
MR. FICK: Now, one of the artifacts that you looked at in Exhibit 1143-01, which I will pull up here -- these are exhibits in evidence. I'm going to go to 1143, 1143-01. You testified about an artifact in this derivative spreadsheet noting that on January 1st at 2013 at 1:47 a.m. there was a log in to Yahoo email for Jahar Tsarnaev. Do you see that?
KEVIN SWINDON: I do see that, yes.
MR. FICK: Isn't it true that that is the one and only time there is any record on this computer of that email account being accessed?
KEVIN SWINDON: I don't have that information in front of me.
KEVIN SWINDON: I don't know that to be true.
KEVIN SWINDON: I don't know it's not true.
MR. FICK: Sitting here today you can't say whether there was ever another occasion on which Jahar Tsarnaev's email was accessed from that computer?
KEVIN SWINDON: I don't have the information in front of me to make that determination.
MR. FICK: And I'm going to also open 1143-05A, which is a derivative spreadsheet -- sorry. One moment. Bear with me one moment.
(Pause.)
MR. FICK: So 1143-05A is the complete -- well, it's the lengthy 2,000 page or so long complete spreadsheet of the files from the Hewlett-Packard computer at 410 Norfolk, correct?
KEVIN SWINDON: It was generated, yes, by X-Ways Forensics, yes.
MR. FICK: And I just want to draw your attention to the date and time information that's generated on this spreadsheet on this computer. You see there's some -- some of the date and time information has real, like, normal dates and times after it. Do you see that? And then some of the same columns have information that does not appear to be in the format of a date or time?
KEVIN SWINDON: Okay. That's what -- that's what this -- you're displaying, yes.
KEVIN SWINDON: The complete list was -- the complete list that X-Ways Forensics generated was provided as an exhibit, yes.
KEVIN SWINDON: If you're looking at --
KEVIN SWINDON: Okay.
MR. FICK: So at least in this form, this spreadsheet could not be used to verify any of the filed time data in your derivative spreadsheet because it's missing --
KEVIN SWINDON: I'm not sure all of the columns have the time and date listed the way that it is but, again, we used both AD Labs and X-Ways Forensics to verify the information.
KEVIN SWINDON: I do not know which one.
MR. FICK: Can you explain why this particular tool generated date and time information that's not comprehensible?
KEVIN SWINDON: I don't know.
MR. FICK: I'm going to go now to Exhibit 1150 which is the Kingston thumb drive found in the landfill that you talked about. Do you remember that? Do you remember talking about that?
KEVIN SWINDON: If you could bring up the spreadsheet again we could confirm.
MR. FICK: Hold on. Exhibit 1145-01 -- I'm sorry -- 1150-01. Now, the bulk of the files that you talked about on this thumb drive were carved; in other words, they were recovered from deleted space, correct?
KEVIN SWINDON: They were either recovered or carved, yes.
MR. FICK: And when we see this path, "path unknown" with all of that -- those numbers, et cetera, directory markers before the file name, that's an indication that the file was carved, right?
KEVIN SWINDON: Using this particular software product, yes, it would tell you that -- that CL is a cluster number of where that file was located or started.
KEVIN SWINDON: There's not. As again, with carved and deleted files, it's more of access for investigative purposes than it is for the date and timestamps.
MR. FICK: And one of the carved items retrieved from this thumb drive, Exhibit 1150-09, was a rental application from Katherine Tsarnaev, correct?
KEVIN SWINDON: Yes.
KEVIN SWINDON: If that's '09, then yes.
MR. FICK: Let's talk a little bit more about 1475 which is the hard drive seized from the street in Watertown. The derivative file listing for that exhibit -- actually, rather than showing you the file listing, what I think I'm going to do is go to the file directory here. Now, you testified last week and I think today that these four folders at the top here actually existed in that form on that hard drive, right?
KEVIN SWINDON: Yes, I believe so. Yes.
MR. FICK: And this English paper that's still listed on the top here, that actually was not visible in the hard drive as an active file at the time it was seized. That, in fact, was carved from having been deleted at some point in the past, correct?
KEVIN SWINDON: Yes.
MR. FICK: And the hard drive sort of contains a kind of greatest hits collection, right? There's Awlaki materials, audio files in that first folder, right?
KEVIN SWINDON: I'm not sure what you mean by "greatest hits" but --
MR. FICK: Well, a lot of files that we've seen on -- that you talked about from the Sony and other devices, a lot of those files -- a very large number of them are all here collected together on this hard drive from Laurel Street in Watertown. Is that right?
KEVIN SWINDON: Can you slide the screen over so I can see the next half?
KEVIN SWINDON: Those are a collection of Awlaki files, yes.
KEVIN SWINDON: There are Russian textbooks in there, yes.
MR. FICK: Well, and you remember looking at the translations from the derivative file exhibit that the titles have to do with explosives and munitions and that kind of thing, right?
KEVIN SWINDON: You're going to refer to each of them specifically or do you want --
MR. FICK: Well, as a general category. You've looked at the translations of these titles in your spreadsheet, right?
KEVIN SWINDON: Well, yeah. Do you want to make reference back to that or are you asking --
MR. FICK: I'm trying to ask some general questions about the category, the type of materials first. If you want to look at the list, we can.
KEVIN SWINDON: Well, if you'd like to ask me specifically, I can comment on --
MR. FICK: Well, the first thing I want to do is ask as a general matter this collection of DjVu e-reader files in Russian, it's a collection of lengthy texts about explosives and munitions, correct?
KEVIN SWINDON: We can go through each one and look at the top page and I can tell you --
MR. FICK: Well, your own exhibit, the derivative exhibit, contains translations in the side, right, titles include "Detonation of Explosive Media," "Physics of Explosion and Impact," "Blast Effects of Explosions," "Initiating Explosive Substances," et cetera, right? Those are the titles of those files, correct?
KEVIN SWINDON: Yes.
MR. FICK: And you testified that carved artifacts of those files were found on one of the thumb drives, right?
KEVIN SWINDON: Yes.
MR. FICK: But it's true, isn't it, that none of these files or any artifacts reflecting these files exist on the Sony VAIO computer?
KEVIN SWINDON: I'd have to go back to the information that we have, but I don't have that all committed to memory. I mean, I do know they existed here. If you would like to go back and look at the file listing we can identify whether or not they were there.
MR. FICK: As far as you know sitting here today it's true, isn't it, or at least as far as you can recall, that these files do not exist on the Sony VAIO?
KEVIN SWINDON: I don't know that for a fact. I would have to go back and look at the listing.
KEVIN SWINDON: I don't have the information to make that determination.
MR. FICK: Okay. Now, in addition to those materials, there's a collection of Inspire magazines as well, right?
KEVIN SWINDON: Yes.
MR. FICK: Okay. And there were also some files on the top level of this hard drive that -- when it was recovered that were not included in this exhibit, correct?
KEVIN SWINDON: I think there were. I was asked to verify these to make sure that they existed.
MR. FICK: Okay. I just want to pull out some things from the complete file listing just to nail that down. Pulling up a page out of 1475-02A, which is the complete file listing from this drive, there were some other items at the top level of the drive that are highlighted in yellow here that we have seen on other exhibits but that also were on this hard drive recovered in Watertown, correct?
KEVIN SWINDON: Yes. If this is from 02A, then, yes, that is a directory listing from the drive.
MR. FICK: So "Book of the End," "Join the Caravan," those are all on, as well, the top level of this hard drive when it was recovered, correct?
KEVIN SWINDON: Apparently so, yes.
MR. FICK: And further down the file list you're aware that there are a couple of Russian language documents also on the top level of this drive when it was recovered, correct?
KEVIN SWINDON: Yes.
MR. FICK: And these are documents that have Russian language instructions about making explosives, correct?
KEVIN SWINDON: I don't know that.
KEVIN SWINDON: No, I did not look in the translation for those files.
MR. FICK: Did anybody under your supervision at the CART team of the FBI ever find out what was in those files?
KEVIN SWINDON: Not that I'm aware of.
MR. CHAKRAVARTY: Objection, your Honor.
THE COURT: No, it may stand.
BY MR. FICK:
MR. FICK: Now, isn't it true that this hard drive retrieved on Laurel Street in Watertown was formatted by Tamerlan's Samsung computer?
KEVIN SWINDON: I don't have the information to determine that.
KEVIN SWINDON: I do not have the information to determine that.
MR. FICK: Well, whether you have it in front of you now, do you know from anything you ever did in the case whether that is true?
KEVIN SWINDON: I don't have the information in front of me to confirm that.
MR. FICK: Again, putting apart what you do or don't have in front of you, did you ever become aware from your work on this case as a supervisor of the Boston CART team whether Tamerlan's computer was the computer that formatted this hard drive?
KEVIN SWINDON: I don't have that information to be able to make that determination.
MR. FICK: Again, I'm asking not only about today but whether you ever came to know -- or whether this was true in the past?
KEVIN SWINDON: I don't know.
KEVIN SWINDON: Checked what, sir?
MR. FICK: Isn't it true that every single file and folder on this hard drive is owned by Tamerlan's computer, using the "owner" as used in Windows parlance?
MR. CHAKRAVARTY: Objection, your Honor.
THE COURT: Overruled.
You may answer it.
KEVIN SWINDON: Again, I don't have that information to be able to make that determination nor did I, you know, validate or verify that.
BY MR. FICK:
MR. FICK: Well, whether you have it in front of you now or validated it or verified it, did you ever become aware in your role as a supervisor of the CART team in Boston that every single file and folder on this hard drive was created by Tamerlan's Samsung computer?
KEVIN SWINDON: I'm not aware of that.
(Counsel confer off the record.)
MR. CHAKRAVARTY: Just briefly, your Honor.
REDIRECT EXAMINATION BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: Agent Swindon, you were asked several questions about different pieces of information on different devices, that you weren't able to recall whether that information that Mr. Fick asked you was, in fact, on those devices. Can you explain for the jury what the conditions are in which you go through in order to verify that certain documents are, in fact, on the different devices that you've talked about?
KEVIN SWINDON: It was different for each of the different -- it was a variety of devices and a variety of different types of files. In they were in active space and an MD5 was available, as we spoke earlier, we would do that MD5 match to verify that that was there. If they were carved in recovered space, we would sit and go file by file and do a visual as we did like in the DjVu files. So there was -- we used a different -- a variety of different information to verify the information that was on the exhibits.
MR. CHAKRAVARTY: And is this the kind of activity that you can do on the fly when -- during cross-examination?
THE COURT: Sustained.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: What are the circumstances -- what are the resources you have at your disposal to do that?
KEVIN SWINDON: Well, we have the forensic team here in Boston, and we were -- I mean, the process to validate and verify took days to do, 20-hour days, probably four, five days of looking through every single one of the files on the exhibits. And this was just a subset of the totality of all the files that were seized in the case or that were a part of the forensic process in the case.
MR. CHAKRAVARTY: In response to one of the questions from Mr. Fick you said that it's -- you weren't sure what one of the files on one of the -- I think the file system record date was. Is that right?
KEVIN SWINDON: I was actually not sure of where that information actually originated from.
MR. CHAKRAVARTY: Right. And at one point did you know that and just didn't remember?
KEVIN SWINDON: Again, we used a variety of different tools to verify that information.
MR. CHAKRAVARTY: Can I show you something that might refresh your recollection?
KEVIN SWINDON: Okay.
MR. CHAKRAVARTY: May I approach, your Honor?
THE COURT: You may.
THE COURT: Show it to Mr. Fick.
(Pause.)
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: I'm handing you a note. Can you read that to yourself, please?
KEVIN SWINDON: Okay.
MR. CHAKRAVARTY: Does that help refresh your recollection?
KEVIN SWINDON: It puts the information in context.
MR. CHAKRAVARTY: All right. And is that just a note?
KEVIN SWINDON: It's just a handwritten note.
MR. CHAKRAVARTY: What I've just handed you is a handwritten note?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: With that information could you explain what the file system record date was that was in that column?
KEVIN SWINDON: The record column was the column, as we had spoken about, was created by AD Labs, or was taken from AD Labs.
MR. CHAKRAVARTY: And is that your memory that you're testifying from?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: And so various tools -- different tools were used at different times in order to both extract data as well as to verify data. Is that fair to say?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: And if you used two different tools to do the same function, does it sometimes produce different results?
KEVIN SWINDON: It depends on where it's pulling that information from.
MR. CHAKRAVARTY: So if you're comparing data from one tool with data from another tool, is that like comparing apples to oranges?
KEVIN SWINDON: For the most part, yes. The tools are tested and validated, although there are different version of the tools. And, again, I would have to go back to the original tool to get to the specific on that.
MR. CHAKRAVARTY: Mr. Fick asked you about some of the activity that occurred on the Sony VAIO computer. And when you had extracted files from the Sony VAIO computer, did you make observations of other files that were on that computer other than the ones that you extracted?
KEVIN SWINDON: I didn't extract the files; I just utilized the exhibits and went back to the original file set in the software and determined that they were there.
MR. CHAKRAVARTY: And were you able to make a determination as to who the user was of that Sony VAIO computer?
KEVIN SWINDON: Based on the activity that we were preparing and verifying from the exhibits that -- you know, we determined that it was Jahar's laptop.
MR. CHAKRAVARTY: And the fact that other devices were also plugged into that laptop, how did you come to that conclusion?
KEVIN SWINDON: Well, again, as we had spoke about before, in the registry there is a report that will track all of the physical devices that are plugged in through the USB ports.
MR. CHAKRAVARTY: So when Mr. Fick asked you as to whether some of the dates of the creation of some files on that laptop predated -- I think the date that he used was September 2011, does -- from the file listing, if the file listing was created -- or showed that a file was created after September of 2011, could you conclude as to who the likely user of that laptop was for that file list?
KEVIN SWINDON: I'm not sure. Can you rephrase the question?
MR. CHAKRAVARTY: I'll rephrase. It was a bad question. The complete file listing, did it show the dates that the files were accessed on that computer?
KEVIN SWINDON: It would show a created/modified/accessed in the file record or born-on update.
MR. CHAKRAVARTY: And you described that no good computer forensic scientist would rely exclusively on the Windows information. Is that right?
KEVIN SWINDON: There are a number of different pieces of information that we would draw on to make a determination.
MR. CHAKRAVARTY: Okay. And could you explain just to the jury why just if they see a date, that's not dispositive as to when something might be accessed?
KEVIN SWINDON: Well, it depends -- when files are created, depending on where they're created, sometimes if they were created on the Internet and you put a thumb drive in a computer and download that file from the Internet to the thumb drive, it's never really born on the computer; it could have been created someplace else and then written to the thumb drive. So you would have to use a number of different pieces of information to determine the actual, you know, creation date on that computer.
MR. CHAKRAVARTY: And so the file that Mr. Fick showed you actually had a creation date of October 10th of 2011. Do you remember that?
KEVIN SWINDON: Which file? He showed me --
MR. CHAKRAVARTY: I think it was the Five Ground Rules. It was a very dense chart. It's not worth putting it back up on the screen, but it was a very dense chart that you had to zoom in on. Do you remember that?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: And so October 10, 2011, in the complete file listing, what does that mean?
KEVIN SWINDON: What column was that --
MR. CHAKRAVARTY: I think it was in the creation --
KEVIN SWINDON: In the creation? With the X-Ways report, it would have been when that was created, or created on that computer.
MR. CHAKRAVARTY: So that means during the school year of 2011, that file was created on the Sony laptop?
THE COURT: Sustained.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: What does that tell you about the -- in relation to the school year as to when that file was created on the Sony laptop?
THE COURT: Sustained.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: Can you conclude anything about the creation date of that file on that computer?
KEVIN SWINDON: Other than the report shows that it was that date of October 11th.
MR. CHAKRAVARTY: Call up 1143-01.
MR. CHAKRAVARTY: This was a document that Mr. Fick showed you.
MR. CHAKRAVARTY: Can we go down to the last page, or two pages down, please? Keep going down to -- I think it's January 1st. Keep going. Right there.
MR. CHAKRAVARTY: So he highlighted this entry where the JTsarnaev Yahoo mail account was accessed. Is that right? Do you remember that?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: And so if we can go back to the earlier page, Mr. Bruemmer.
MR. CHAKRAVARTY: Just to clarify, this spreadsheet was generated from the desktop computer that was at the residence of 410 Norfolk Street. Is that right?
KEVIN SWINDON: Can you go back up to the top of the report, please?
MR. CHAKRAVARTY: Page 1, please.
KEVIN SWINDON: At 2R14. Yes, the HP desktop.
MR. CHAKRAVARTY: So this showed that somebody logged into the JTsarnaev Yahoo email account on that computer on January 6th?
KEVIN SWINDON: There was a browser history record on that computer of somebody logging into that email account.
MR. CHAKRAVARTY: And Mr. Fick also asked you about when Tamerlan Tsarnaev was not in the country, and he gave you like a six-month period through July of 2012. Do you remember that?
KEVIN SWINDON: He asked that question, yeah.
MR. CHAKRAVARTY: And so all these dates that occurred before July of 2012, that would suggest that it was somebody else using this computer. Is that fair to say?
MR. FICK: Objection. Those aren't the dates on the screen. The dates on the screen are 2013 dates. Oh, I'm sorry. I'm on the wrong screen.
THE COURT: All right. Go ahead.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: Sir, you can answer the question. The question was: Does it mean that the user of this computer was not Tamerlan Tsarnaev during that time?
KEVIN SWINDON: It was not Tamerlan Tsarnaev.
MR. CHAKRAVARTY: So all of this ESPN, MTV, all that stuff was not Tamerlan Tsarnaev, right?
KEVIN SWINDON: It was not.
MR. CHAKRAVARTY: Okay.
MR. CHAKRAVARTY: Can we go to the next page?
MR. CHAKRAVARTY: And that goes on for another page.
MR. CHAKRAVARTY: Go down to the next page.
MR. CHAKRAVARTY: And another page. It looks like somebody's watching "Teen Wolf."
MR. CHAKRAVARTY: Next page.
MR. CHAKRAVARTY: And Netflix as well, and then "Walking Dead." These are all things that that person liked to watch?
KEVIN SWINDON: That was the Internet access that was recorded during that time.
MR. CHAKRAVARTY: Now can we go to the file listing of 1143?
MR. CHAKRAVARTY: So going back to 1143, we called up one of the folder directories. These are some of the files that were on the 1143, the desktop computer in the Norfolk Street residence, right?
KEVIN SWINDON: Except for the ones that are denoted with an A, they're actually the translations for the files that correspond to the numbers.
MR. CHAKRAVARTY: So all of the "Hereafter Series" is in there from Anwar Awlaki. Is that right?
KEVIN SWINDON: Yes, they are in that folder.
MR. CHAKRAVARTY: And a number of audio files, or nasheeds. Is that right?
KEVIN SWINDON: Can you scroll over for a second?
MR. CHAKRAVARTY: In fact, some of these nasheeds were also found on the 1R6. Is that fair to say?
KEVIN SWINDON: I would have to look at the verification, but I recognize some of the titles from --
MR. CHAKRAVARTY: Some of the titles. But until you see an MD5#, you wouldn't be able to --
MR. CHAKRAVARTY: And there's some videos as well?
KEVIN SWINDON: That came out of the new folder, yes.
THE COURT: All right.
MR. CHAKRAVARTY: I'm done with this.
THE COURT: All right.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: Now, you were also asked about whether there were any other computers in the Tsarnaev family household prior to this desktop computer that -- whether you were aware of any other computers. Do you remember that?
KEVIN SWINDON: Yes, I was asked that question, yes.
MR. CHAKRAVARTY: And going to 1557, we haven't talked much about the 2R58. Do you see that?
KEVIN SWINDON: Yes.
MR. CHAKRAVARTY: What do you know about that device?
KEVIN SWINDON: Well, from the description --
THE COURT: Sustained.
BY MR. CHAKRAVARTY:
MR. CHAKRAVARTY: Were there other devices found in 410 Norfolk Street?
KEVIN SWINDON: There are other devices on this list that were found from 410 Norfolk Street.
MR. CHAKRAVARTY: And with regard to the data that is on the disks that you've entered into evidence, with the exception of those pieces such as translations and the derivative analytical products which have some titles and things on them, was everything else that you brought into court actually found on each of the devices that you have talked about?
KEVIN SWINDON: With the exceptions that we spoke about this morning with the titles of the corrupted files and the DjVu files that were converted, yes.
MR. CHAKRAVARTY: That's all I have, your Honor.
(Pause.)
THE COURT: I'm waiting for something to come up.
THE COURT: No, I have it. I'm just waiting to see whether there's an image and then I'll expose it.
(Pause.)
RECROSS-EXAMINATION BY MR. FICK:
MR. FICK: Now, Mr. Chakravarty asked you some questions to clarify -- or at least try to clarify the meaning of this file -- system record date in local time, right?
KEVIN SWINDON: Yes.
KEVIN SWINDON: I don't recognize the handwriting on that.
MR. FICK: So anyway, your answer to the question was the data from the second column came from the AD Labs tool, right?
KEVIN SWINDON: I said the record column is in AD Labs. That's what all that --
MR. FICK: All right. But regardless of what tool we're talking about, all of these tools extract information from the -- from Windows and from the Windows metadata, correct?
KEVIN SWINDON: They do. But they also could interpret it in different ways.
MR. FICK: But ultimately there is an answer, for example, to the question about when a file was created on a local computer, right?
KEVIN SWINDON: There's information available from numerous sources that were used to determine when that file was created on that computer.
MR. FICK: And if tools conflict, one would have to look deeper to figure out what the conflict is and answer the question, right?
KEVIN SWINDON: They would have to do some additional analysis to determine that.
MR. FICK: Now, quite apart from what tool generated this file system record date, my question is still which Windows artifact is the file system record date?
KEVIN SWINDON: I'd have to check with AD Labs. I don't have that information sitting here today.
MR. FICK: Okay. So even if now you remember from the handwritten note that AD Labs generated this information, you still can't tell me what that information means?
KEVIN SWINDON: Not without having the software in front of me, no.
THE COURT: All right, Agent. Thank you. You may step down.
KEVIN SWINDON: Thank you.
(The witness is excused.
THE COURT: All right.
(Discussion at sidebar and out of the hearing of the jury:)
MR. FICK: In light of the witness's testimony on his lack of foundation and knowledge about how the various derivative spreadsheets were generated and the accuracy of the data they're in, we would renew our foundation and confrontation objections and move to strike all of the exhibits.
MR. CHAKRAVARTY: I think he laid a sufficient foundation for the exhibits. He individually verified each entry both on the spreadsheets as well as the files that were extracted, and I think it's sufficient.
THE COURT: I think it's sufficient for admission. It goes to the weight and the jury's evaluation.
(In open court:)
MR. CHAKRAVARTY: The government calls Dr. Matthew Levitt.
