9:06 am
employed? you are a forensic scientist? >> i'm a forensic scientist. >> could you describe to the jury the background to be a forensic scientist? >> i have a bachelors, and a masters from george washington university. >> when did you achieve your bachelors of science degree? forensic science? >> 2007. >> where from? >> university of south dakota. >> you said that already. >> so you worked on a master's, where did you get that george washington? >> george washington. >> what year was na. >> 2009. >> what do you have to do to get a masters in forensic science? >> the course work included criminal justice course work, law courses, there was a lot of hands-on many a --
9:07 am
application of forensic practices and my concentration was forensic molecular biology and dna testing. >> after you achieved your bachelor's degree in forensics science and working on your master's, did you work in the field as well? >> yes. >> where did you initially start? >> at a lab bodie technology out in virginia, it was a private forensic laboratory and i did dna testing while there. >> prior to that, did you have experience at bca? >> prior to that i was an intern at the bca between my first and second year of graduate school. >> and what kind of work did you do during your internship? >> i did project with our lay tennant print section and also with the mitochondrial dna
9:08 am
section had to do with validating a new instrument they were using at the time. >> so then you went to work with bote technology, that's b-o-te. >> correct. >> what did you do there? >> i started working in the group customized case, would -- casework. i did technician work for them and then moved to a role in the data basing. so i did convicted offender samples from a variety of states who contracted with that lab. >> and so, at some point did you leave that lab, obviously? >> yes. >> where did you go? >> i started with bca in 2009, october of 2009. >> and what job did you take at the bca? >> i was hired on as a forensic scientist in the biology section. >> and what does the biology section do?
9:09 am
>> the biology section does dna testing and also body fluid identification, which is the identification of bodily fluids as it's relevant to a case and including sample collection from a variety of physical items of evidence that come into the lab for dna testing. >> so when did you start doing that? >> i was hired in october of 2009. >> when you get that job for the bca, was there specific training they made you go through because you were hired by the bca? >> yes. >> can you describe that for the jury? >> so the dna training program takes a year to complete. typically people start with that body fluid identification portion first, they'll get trained in that and then move on to dna testing. >> so all of that training includes watching other scientists do their work. many practice samples, competency sets that we need to
9:10 am
do. we do written tests, oral tests before we are some kind off and able to work independently and issue our own reports. >> so are you still working in the biology section? >> yes. >> and at some point did you take on additional responsibilities at the bca? >> yes. in 2014 i joined our crime scene team. >> and have you been working crime scene team since then? >> yes. >> at some point did you become a crime scene team leader? >> yes, i did, in 2016. and we'll come back to that in a little bit. are you a member of any professional organizations or affiliations? >> i am, i am a member of the association of forensic sciences and also american academy of forensic sciences. >> so we've heard a little
9:11 am
about the bca, the different divisions they have, you're in the laboratory division, correct? >> correct. >> can you describe to the jury what it does, not in any great detail. >> they have a number of section, that include dna, direct chemistry, lay tennant prints, firearms, toxicology so depending on what the item of evidence is, it gets routed to the appropriate section. lab. sometimes there are items of evidence, items that we work on in multiple sections of the lab so just kind of depends what the request is and what the item of evidence is that we're working on. >> and is the crime scene team considered a separate section? >> yes. >> do you know how many crime scene teams there are? >> we have two main crime scene teams. we have a team down in st. paul
9:12 am
at our bca headquarters and a second team up in our regional lab. >> and so when did you-- you started working on a crime scene team in approximately what did you say, 2014? >> yes. >> and you became a team leader in 2016? >> correct. >> is there something you need to do to become a crime scene leader? >> yes, in order to join the crime scene team initially, there's a lot of training that we go through at the lab that includes, you know, lectures and presentations and handon practical exercises, oral boards in order to join the team. to become a team leader there is some additional training that we go through specifically that covers sceny-- scene reconstruction, and
9:13 am
before we issue reports in those. >> you're working now, in the both section, the crime scene time and the dna or biology section? >> that's correct. >> so when you're on a crime scene team, who you do you generally get called out on a particular case? >> so we're on call on a rotational basis, we're on call for at week at a time. when we're on call, we're available 24/7 to respond to a potential crime scene and our requests come in from an agent to will call me and kind of give me a synopsis or a rundown. case that they have and the request that they have for us to come out and if it meets our criteria, i will send out word to the rest of the crime scene team that we need to respond. >> any idea -- well, let's look at like the last year, how many
9:14 am
crime scenes you've been to? >> last year i responded to about 30 crime scenes. >> last calendar year? >> yes. >> so 30 been a typical year? >> that's more than normal. >> now, is the lab, the bca lab accredited? >> yes, we are. >> can you describe to the jury what that means to be accredited? >> accreditation is a process in which trained auditors and assessors and other scientists who work in the field come into our lab and do an independent assessment on our entire quality system and all of our laboratory systems and they evaluate us on hundreds of criteria to make sure that we're qualified to perform the testing that we do. >> and do you know how long the lab has been accredited? >> we have been accredited since the '90s, since 1994. >> over time, different
9:15 am
accrediting boards? >> yes, that's correct. >> and have you gone through the accreditation process? >> yes, i have been employed while we have gone through many accreditation cycles. so it's a fancy way of saying your work gets checked by other individuals? >> yes. >> does the lab also perform audits of other labs for their accreditation? >> yes, we do. >> and were you called to a scene on may 25th of 2020? >> yes, i was. >> and how did you get called out? do you remember how that call came to you? >> i received a phone call from assistant special agent in charge mike phil around 11:30 on the night of may 25th, 2020 and he requested crime scene assistance to a scene in south minneapolis. >> and did you, in fact, then
9:16 am
respond? >> yes. >> could you tell the jurors who all was on the crime scene that night? >> our team consists, of a team leader, a technician, a photographer with the bca. for this particular scene i responded with myself and technology, i decided not to go with the member initially and let him know that we might need him if it came-- if more information came to light, but initially i responded to the scene with myself, the technology and our photographer. >> and so when you get this call, you gather them together and head to that scene, correct? >> yes. the laboratory scientist on the crime scene team, we respond to the headquarters in st. paul so then we can grab our crime scene truck and we all respond together. >> the crime scene truck has all of your equipment ap stuff you need? >> yes.
9:17 am
>> and what we sometimes see on tv a crime scene like almost an rv? >> yes, exactly. >> and do you recall going to the scene then in minneapolis because of this? >> yes. >> and do you recall what time it was that you arrived on scene? >> we arrived on scene, it was about 1:15, so early in the morning on the 26th. >> and do you recall how long you were at that scene? >> we were there for a little over two hours. >> and that location in minneapolis, do you remember the intersection? >> yes, it was at the intersection of chicago avenue and east 38th street. >> and when you get there, what is sort of the first step in the process? >> when the team arrives, we get a briefing from the agent on scene. >> and what kind of information did you learn at that point? >> the briefing that we got included that an employee of
9:18 am
the cup foods restaurant called 911 when they suspected someone was using what they thought could be counterfeit money. minneapolis police officers arrived to the scene. they attempted to arrest mr. floyd. there was a little-- perhaps a little struggle to get him into the back seat of the squad car. eventually he was moved to the ground. at some point mr. floyd became unresponsive and was then taken by ambulance to hcmc. >> so that's the information you were given about why this was a scene? >> yes. >> and from there then did you proceed to process that area? >> yes. >> and can you describe when you first arrived, you know, what you see as that scene? general? >> when we first arrived we saw
9:19 am
at that intersection there were two vehicles parked on east 38th street. there was a mercedes benz suv and a minneapolis squad car parked behind it on 38th street by dragon wok restaurant. other than that, there wasn't a whole lot else that was around at the time. there was-- it was raining when we got there and from my quick walk through that we do with the agents, i didn't necessarily see a lot of processing that was potentially going to be needed at that particular scene. >> and at some point when you were at the scene did you become aware that there had been a video taken of the incident? >> yes, after we had been on scene for a little while, i was made aware of a video. >> did you watch a portion of that video? >> i did watch just a small portion of it. >> and did that help you try
9:20 am
and locate things-- areas that might be of interest? >> yes, the primary reason for watching it was, we didn't know exactly where the incident had occurred. the assumption was when we got there was that it happened where the squad car was packed, by watching the video we could see it was around the corner on chicago avenue. the objective of watching the video for me to see where mr. floyd would have been on the street so i could specifically look at that part of the street. and did you. >> yes was it part of the process to take photographs of the scene. >> yes. >> and have you or did you in fact take a number of photographs of the scene? >> yes, the special agent who was with me took a number of photographs on scene. >> and would those photographs help you describe to the jury what you saw at the scene that
9:21 am
night. >> yes. >> and have we shown you previously what had been marked as exhibits 129-135? >> yes. >> and do those appear to be photographs taken that night of the scene? >> yes. >> your honor we would offer 129 through 135. >> any objection? >> no objection. >> 129 through 135 inclusive are received. >> and then we'll publish 129, please. can you describe for the jurors what is depicted in this photograph? >> in exhibit 129, this is a photograph of the photographer is standing on chicago avenue basing south, that cross street that you see is east 38th street. cup foods is on the left, on the corner of that intersection and then just beyond that, you can see a portion of the minneapolis squad car. >> and appears to be what we call crime scene tape, correct? >> yes, or the crime scene tape
9:22 am
was up prior to the arrival of the crime scene team. >> and moving to exhibit 130. describe this, please. >> this is a photograph taken, again, from chicago avenue looking north and it's another view of cup foods. >> and exhibit 131? >> 131 is a photograph from 38th street looking east. this is a view of the mercedes benz suv and also the squad car parked behind it. >> and does this photograph also show some of the crime scene tape? >> yes, it does. >> and there's a stylus in front of you if you want to just point it out to the jurors on the screen. >> there's crime scene tape running along in front of the suv and then there's a little bit of crime scene tape further down the block as well.
9:23 am
>> and did the crime scene tape appear to be appropriate for securing that scene? >> yes, i thought so. >> did it, in fact, essentially encircle that intersection? >> yes, it does. >> and going to exhibit 132. describe this for the jurors as well pan if you also just point out the crime scene tape here. >> sure. this is a photo on east 38th street again, this view is looking west and it shows the mercedes benz in the foreground, the minneapolis squad car parked behind it. there's crime scene tape behind the squad and then a little bit further down on the other side of the intersection as well. >> and when you are -- well,
9:24 am
let's go to exhibit 133 then as well. do you see this -- can you describe this for the jurors, please? >> exhibit 133 is a photo taken across the street from where that other photo was that we just saw. this was on the same sidewalk as cup foods that read belong to cup foods and this is looking west on 38th. >> when you're at a crime scene outdoors like this, do you also try to locate the security cameras? >> yes, that's part of what we do. >> in this photograph, part of exhibit 133 do you see some security cameras that you spotted while you were there? >> yes, there are a couple crime-- or a couple of security cameras. do you want me to circle them? >> sure. so that's just customary to take note of those for
9:25 am
investigative purposes? >> it is. >> i'm going to ask at that back up to 132, please. and this is where we're seeing the other side of the street by the dragon wok, is that correct? >> yes. >> is there a security it camera in this photograph as well? >> oh, yeah, sorry, there's this one on dragon wok on the corner. >> and then going to exhibit 134, describe this for the jurors as well. >> this is a photograph taken from chicago avenue slightly closer to cup foods. cup foods is that building on the left and then, you can also see squad 320 in full view on the other side of 38th street. >> so the crime scene tape was almost redundant in some areas, right? >> it was a little, yes.
9:26 am
>> and are there security cameras visible in this photograph as well? >> yes. you can see the one on dragon wok and the one underneath the awning of cup foods. >> so now if we go to exhibit 135, is there a better view of that? >> yes. exhibit 135 is a photograph specifically of the security camera underneath the awning of cup foods. >> and when you-- take that down. when you're out there, you make note of those security cameras for investigators? >> yes. >> when you were at the scene did you notice any blood at the scene? >> no. i searched the street around where the squad car was parked. the street and the sidewalk and then also the street and the sidewalk when we had watched the video, the approximate location that we thought he
9:27 am
could have been and i did not see any blood. >> but you understood that it had rained since the event and could have interfered with the scene? >> it could have. >> and then you noticed the two vehicles present. other than those two vehicles did you collect any evident from the scene? >> no, there was no evidence collected from the scene. >> and what was decided about what to do with the vehicles? >> it was decided that both of the vehicles would be towed back to the bca for further processing. >> why would you process them at the garage rather than out there? >> it's a common practice for us to tow vehicles back to the bca so we can process them in a more controlled environment with better lighting, you know, we're not out there in the dark in the rain and we can do it in a controlled setting with all of the equipment that we need around. >> so were those vehicles, in fact, towed from the scene? >> they were.
9:28 am
>> were you present when that was done? >> yes. >> and agent reyerson was involved in that process, is that correct? >> he was. >> and so then you left the scene after that approximately 3:30 in the morning? >> yes. >> so what was the next step in the process for the crime scene team then? >> the next step that we did, i arranged with agent reyerson to the agreed upon time to process the actual vehicle and so we agreed that we would do them on may 27th. >> so that would be essentially the next day now, correct? >> yes. >> is that customary to wait a day to process a vehicle? >> it is. >> where were the vehicles at that time? >> they both were towed to a secure garage that we have at the bca that we use for processing vehicles.
9:29 am
>> and did you then, in fact, process the vehicles on may 27th? >> yes, we did. >> do you remember when approximately you began processing those vehicles? >> we started at about 9:00 in the morning, i'd say, processing the vehicles. >> who all was involved in processing the vehicles? >> to process the vehicles, it was myself, a team member and an agent who is taking photographs for us. >> and can you just describe the overall process you're going to take when you're going to process a vehicle. so the first step that we do, we will photograph and document the outside of the vehicle in its condition that it was when we towed it from the scene. after that, we'll open up the doors and take photographs of the interior of the vehicle. as it is before anybody moves or touches anything. so then after that, we start going through the contents of the vehicle and marking items
9:30 am
as necessary for collection. >> and when you processed these vehicles, you know, what kind of information did you have about the incident itself? did you get any further information than when you were originally at the scene? >> no, there really was very little additional information that was known at the time, so not much had changed, i guess from my perspective, from just that day that had passed. >> we saw a lot of photographs of the scene. did you also take a lot of photographs of the vehicles? >> yes. >> what's the purpose of taking that many photographs? >> just documentation purposes so we can photograph, like i said, the condition of everything that it was prior to us doing anything or moving anything, and then as we move objects around, and as we find items of evidence, we're documenting and photographing its location, the condition of
9:31 am
the items that we're taking, just so everything is thoroughly documented and someone else can then look at the photos and get an idea of what we did. >> and when you are processing a vehicle, do you always know for sure what would become an item of evidence in the future? >> no, that can be said about anything vehicle or anything that we really process. >> when you started the processing of these vehicles, did you know that they were going to be kept by the bca? >> yes, i do believe i knew the intention was always to hold onto the vehicles, yes. >> so even after you processed them, they're going to stay in the custody of the bca? >> yes. >> and have you looked at what we've marked as exhibits 137 through 149. >> yes. >> and do you recognize those as photographs taken during the processing of the mercedes benz suv? >> yes.
9:32 am
>> and would those photographs help you explain what you did to the jury. >> yes. >> and offer exhibits 137 through 149. >> any objection? >> no objection. >> 137 through 149 are received. >> then let's go to 137, please. so is this then the mercedes suv that you processed on may 27th? >> yes, this is the suv we processed and this is the condition it was the morning that we started the processing. >> and where is this location? >> this is in the bca processing garage at our headquarters in st. paul's. >> do you remember at the time you did this processing, what information you had about this vehicle itself? >> the information that i had that was kind of helping guide my search of the vehicle, again, was just that there was potentially some blood that could be present on either of
9:33 am
the vehicles. the other thing that i knew about was money. the potential to be-- to have counterfeit money, could be found in any of the vehicles, so i had those things in mind. other than that, there wasn't necessarily anything specific i was looking for, just looking through to see if there's anything of note that i needed to collect forensically or investigatively. >> and why did you think there might be some blood to look for? >> just because of the information that i had and the briefing at the scene, that there was a little bit of a struggle to perhaps get mr. floyd in the back seat of the squad car and i had information that he could have been bleeding possibly from the nose or mouth. >> and did you have any information whether he may have been under the influence of something? >> no, i did not have that information at that time. >> when you--
9:34 am
all right, so let's go to exhibit 138 then. >> and describe what's depicted here. >> exhibit 138 is a photo of the driver's seats of the vehicle with the driver side door open. >> and this is how it appeared upon first opening the suv? >> yes, this is how it appeared when we first opened it and before anything had been moved or collected. >> then let's go to exhibit 139. >> i'm sorry. we apparently haven't put those up on the screen. can we go back to 138? and actually, i guess 137.
9:35 am
these were not up on the screen earlier, correct? and again, 137 depicts the vehicle in your garage, correct? >> yes. >> and then 138, can you put that up, please? and that is the driver's side as it appeared? >> yes. >> and then i think we're on 139. and this is the front passenger side, correct? >> yes, that's correct. >> and in the center of this photograph you'll see a blue bag or envelope. do you see that? >> yes. >> are you familiar with what that is? >> yes. >> can you describe that for the jurors, please? >> that is called a faraday bag. and we use to put electronics in, specifically cell phones, so there was a cell phone observed on the front passenger seat of the vehicle and that was put in that bag by agents prior to towing the vehicle.
9:36 am
the about upper of that is to prevent anyone from remotely accessing a cell phone or trying to perhaps delete data or change anything on the phone. >> so essentially locks people out of that phone? >> yes. >> and then 140, please? >> and again, describe this for the jurors. >> this is a photo of the rear passenger side of that suv. >> and exhibit 141? >> can you describe that for the. >> caller:,? >> this is a photo of the trunk area of the suv with the lift gate open. >> and going to exhibit 142. can you describe what's depicted in this photograph? >> this is photo that is of the front passenger seat area of the vehicle a little closer in, you can see a portion of the floor of the seats and the
9:37 am
center console. >> the center console there appears to be what looks like a small white, looks like a pill. >> yes, next to there is a small white pill. >> when this photograph was taken did you have any knowledge that the case had anything to do with pills? >> no, not at all. >> so then you preserved this area by taking photographs of it all, correct? >> correct. >> and that becomes part of the investigative file of the photographs? >> yes. >> and after the vehicle is it fully processed, what's the process you go with it? >> after everything is photographed, at that point then i start marking items for evidence collection by putting down item tense or item number and those are rephotographed after i mark them.
9:38 am
>> and in fact, during this search, did you remove some money from the vehicle? >> yes, i did. >> where was that money located. >> money was located on -- there was one bill on the front passenger seat and the other bills were in the gap between the front passenger seat and the center console. >> and can you show the jurors kind of in this photograph, 142, where that would be? >> it was in this gap, but a little bit further back of the seat. >> i'm sorry, were they easily visible there or-- >> no, you can't see it here. >> were they stuffed down in between? >> they were. >> and have you also seen what we've marked as exhibit 136. >> yes. >> is that photograph taken after the vehicle was
9:39 am
processed? >> yes. >> we'd like to enter 136. >> any objection? >> no objection. >> i've gone out of order, your honor, thank you. that's how this works. so 136, you see the vehicle here? >> yes. >> there appears to be some red tape on the door areas, can you explain that to the jury? >> yes, once we were done processing the vehicle, all of the doors were taped sealed and initialled like you can see there. >> and why is that done? >> we do that to preserve the item of evidence and to ensure that no one enters the car and if someone has, it would be obvious and that the tape seal is broken. >> and then where is the suv taken after that? >> the suv is towed to a secure storage facility. >> now, with regard to this
9:40 am
blue suv, were you asked to search that again later? >> i was. >> and do you recall when that was that you did that? >> i searched the vehicle for a second time on december 9th of 2020. >> do you recall why that was done? >> special agent reyerson had relayed to me that there was a request from the attorney general's office to collect additional items from the suv. >> and so did you then -- well, did you have -- were you given specific information about what to recover from the vehicle? >> yes, i was given specific things to look for. >> and what was that? >> i was told to collect suboxone bills in the center console. gum, if there was any gum
9:41 am
present and money and also a request to photograph some of the contents of the luggage in the trunk. >> and have you seen what we've marked as exhibits 143 through 149? >> yes. >> and are those photographs taken during the subsequent, the second processing of the suv? >> yes. >> your honor, i'd offer 143 to 149. [inaudible] >> if they aren't received before, they are now. >> they are, i'm sorry. duplicating efforts. and so showing you exhibit 143 again, or showing you 143. and is this photograph-- can we publish this as well, your honor? is this the photograph taken during the second processing of the vehicle? >> yes, it was. >> and were the seals intact when you began that? >> all of those seals were intact on the vehicle. >> and so what are we seeing
9:42 am
here on this evidence tape? what's the handwriting? >> the handwriting is initials cm, it's one of our agents, and then the date that it was taped sealed up initially, so 5-27-2020. >> and did you then break those seals and begin a secondary processing of that? >> yes. >> and i'd like to move that into exhibit 144. and can you describe what's depicted in this photograph? >> in this photograph you can see inside the front driver's side of the suv and there is an item of evidence that has been marked with that 46 item tent. >> and so why do you do that? >> every item that we collect in a case gets its own unique item number so that way we can track it through the lab and the chain of custody after that point when it's collected. >> all right. so let's proceed then to
9:43 am
exhibit 145. and is this now a close-up of item 46? >> yes, this is a close-up of item 46. it was a suboxone packet that was opened on the driver's side floor. >> and are you generally familiar with what suboxone is? >> generally, a little bit. >> what is it? >> it is a prescription medication used for adults with an opioid addiction. >> and so, is this item recovered by you? >> yes. >> and then if we could go to exhibit 146. can you describe what's in this photograph, please? >> in this photograph is an item of evidence that has been marked as item 47, which is on the front driver's seat.
9:44 am
>> and if we can go to exhibit 147. is this then a close-up of item 47? >> yes, this is a close-up of item 47 which was an unopened packet of suboxone on the driver's seat. and can we then proceed to exhibit 148? describe what's depicted in this photograph. >> in exhibit 148 there's an item of evidence marked as bca item 48 and that is referring to the two pills that you can see there in the center console. >> and appears to be the same kind of pill we saw in the previous photograph from the first processing of the vehicle, is that correct? >> yes, that's correct. >> were those the pills that were you specifically asked to retrieve from the vehicle? >> yes, they were. >> and did you in fact take those two pills? >> i did. >> and if we can go to 149.
9:45 am
how many pills did you find there? >> there were two pills in the center console. >> and did you recover them both as item 48? >> yes, both were collected together as item 48. >> so why collect them together? >> because they were in close proximity like you can see there and they both have the same markings on them as well. >> and what did you do with those after you recovered them from the vehicle? >> after they're recovered from the vehicle, they're packaged up by myself and they're taped sealed in a package and they're given a bca bar code so then i can transfer it to the appropriate section of the lab for testing. >> was that done? were they made available to another section. lab? >> yes, they were sent to our drug chemistry section. >> and i understand you did some other work in processing
9:46 am
the vehicle at that time. nothing of additional evidentiary value removed from the vehicle at that time? >> correct. >> and now going back to the initial processing on may 27th, did you also process squad 320 on that day? >> yes. >> and i would ask you if you have looked at exhibits-- well, let's just start with exhibit 150. and is that a photograph taken from the processing of the squad car? >> yes. >> your honor, i'd offer exhibit 150. >> no objection. >> 150 is received. >> we can look at exhibit 150. can you describe that for the jurors, please? >> exhibit 150 is a photograph of minneapolis squad car number 320. this is the condition as it was
9:47 am
towed from the scene and also the morning of the 27th when we began processing on it. >> and this was in the bca garage? >> it is. >> and so i'm now going to offer your honor exhibits 162 to 169. >> any objection? >> no objection. >> okay. 152 to 169. >> we'll skip over 151 and go to 152, please. >> can you describe what's depicted in this photograph for the jurors? >> in exhibit 152, this photograph is of the front driver's side area of the squad car and the door opened. >> and you had some information of a struggle with mr. floyd.
9:48 am
why the driver's side? >> when we process the vehicle we document all of it, regardless of the circumstances, we just will photographically document everything about the vehicle before we start processing it. >> so if we go to 153 now, please. and this is the photograph of what? >> this is a photograph of the driver's side door, like the pocket on the door. >> so when you have this photograph taken, do you have any knowledge that these items have anything to do with the case? >> no. >> just to document it, you take this photograph? >> exactly. >> and exhibit 154, what is this? >> exhibit 154 is a closer photo of the driver's side floor of the squad. >> and again, just to document the scene? >> yes. >> and 155? >> describe this for the
9:49 am
juror, please? >> this is a photograph of the contents of the front passenger side pocket on the door. >> and 156? >> this is a photograph of the front passenger seat of the squad. >> so again, these are just taking the documents for future reference, if needed? >> yes. >> now, i'd like to show you exhibit 157 and can you describe for the jurors what's depicted in this photograph? >> in exhibit 157 this is a photograph of the rear driver's side of the squad, you can see a little bit of the rear driver's side seat and then the interior of the rear driver's side door. >> this is-- well, prior to this had you processed other police squad cars? >> yes. >> all right. i assume as an adult you've sat in the back seat of regular cars before? >> yes. >> the back seat of a squad car
9:50 am
here, different than the typical vehicle? >> yes. >> how so? >> the back seat, you can kind of see the cage, the glass that separates the front of the vehicle from the rear of the vehicle, and all of the plastic that's up on the back side of the seats. the back seat itself is also rubber and, yeah, they're a little different looking, obviously than a regular volk. cloth seats or anything like that. >> and we go to exhibit 158. this is a view into the back seat of the squad car, correct? >> yeah. >> and that's how it looked as you began processing it on may 27th? >> yes, it is. >> and fair to say that the back seat area is a lot smaller in the squad car than it is in
9:51 am
a regular passenger car like this? >> yes. >> and i'm showing you exhibit 159 then. is this a view of the back seat from the other side, the passenger side? >> yes, this is a perspective from the passenger side, the rear passenger side of the squad. >> and exhibit 160 as well. >> this is a photo of the back seat taken from the perspective, again, of the rear passenger side of the vehicle. >> there appears to be a strap item on the back seat. do you see that? >> yes, there was a back strap on the rear passenger seat. >> and there an i pierce -- appears to be a shot on the floor. >> yes, there was a pair of shoes on the floor, and the left shoe is on the floor on the other side. >> on the floor on the other side? >> yes. >> and exhibit 161.
9:52 am
this is a close-up of the right shoe on the passenger side. >> correct. >> and again, just documenting the location of that shoe? >> yes. >> now, if we can go to exhibit 162, what does this depict? >> this is a photograph of the trunk area of the squad. that was a large removable plastic tote that had various items and supplies in it. >> again, didn't have any specific information that this area of the squad car was involved in the incident? >> no, we did not. >> but you still document this. >> yes. >> i think what we can do is scroll through exhibits 163 through 166, please. each of those photographs depict the stuff in the back of
9:53 am
the squad car? >> yes. >> and again, that's done just to document what's there. and certain items -- you can take it down, please. documented by you and recovered? >> yes. >> and did that include the pair of shoes? >> yes. >> and that strap in the vehicle? >> yes. >> and as well did you see any blood stains or what appeared to be blood stains on the vehicle? >> yes, i did. >> i'm going to show you exhibit 167. do you see that photograph? >> yes, yes. >> and so the strap is labeled as what item? >> as item 9. >> and the shoe? >> the shoe is item 8.
9:54 am
>> and were both shoes collected? >> yes. >> and going through exhibit 168, this is a close-up of that shoe, correct? >> correct. >> and was that shoe removed? >> yes, it was. >> and did you, in fact, remove it? >> i did, yes. >> and did it have any apparent blood on it? >> no, blood was not noted on it. >> and exhibit 169? and just describe for us, first of all, the shoe was missing, correct? >> correct. >> so this photograph was taken after you removed it. >> yes. >> and there appears to be a white spot on the floor here on the passenger side, correct? >> yes. >> and if you want to just take the stylus and draw around it. and at the time you removed the shoe did you notice that there? >> i did see it, yes. >> and did you remove it at the
9:55 am
time. >> no, i did not. >> why not? >> at the time, again, i didn't have any information that i was looking for anything like a pill or resembling a pill. it was in the back seat of a squad car, i wasn't exactly sure what it was, if it came off of somebody's shoe. so at the time i didn't give it any forensic significance given the information i had. >> so you left it in that location? >> i did. >> and obviously documented it with photographs. >> yes, correct. >> and when you were searching at that time, really, what was sort of the focus of your forensic processing of this vehicle? >> the focus of it was processing the blood in the back seat. >> and so then there are some
9:56 am
other-- we see some white stickers in this photograph? >> correct. >> we can come back to those later. after this initial processing were you asked to do a subsequent processing of the squad car with relation to that apparent pill on the floor? >> i was. >> and do you know what sort of prompted that second processing of the vehicle? >> i was informed on the morning of january 27th, 2021, i was informed by special agent reyerson that the vehicle, the squad was being towed back to bca headquarters. they had met, some of our agents had met with defense attorneys on the case who had gone through the squad and there was an additional request for evidence collection after that. >> and that specifically was for this bill or other pill-like items in the vehicle? >> yes. >> and so did you, in fact,
9:57 am
then process the squad car a second time with that in mind? >> yes. >> and have you seen exhibits 1170 through 176? >> i have. >> and are those taken from the processing of that vehicle? >> yes. >> your honor, i would offer 170 through 176. >> no objection. >> 170 through 176 inclusive. >> and was it sealed up from the initial processing? >> it was not sealed when i arrived at the garage. >> is that because others had already been in to look for this? >> correct, that was my understanding. >> so we're seeing in exhibit 170 this back seat area, the pill appears to be present there as well, correct? >> yes, the pill is in the position it was on may 27th. >> so let's go to exhibit 171. and did you assign this an item
9:58 am
number. >> yes, i assigned it bca item 51. >> and did you then recover that item? >> i did. >> can you describe-- describe its condition for the jury. >> the pill was round in shape, however, it had a rough textured appearance to it and there were no visible markings on this particular pill. >> did it appear like it wasn't whole any longer? >> yes, i think that's a fair statement, yeah. >> and then if we can go to 172, please. >> so this is a close-up of that item? >> yes, it is. >> and so then you collected that and did you make that available for further testing in the lab? >> i did. >> and i'll come back to that in a minute, too. exhibit 173, can you describe
9:59 am
what's depicted in that photograph? >> in this photograph, i can see an item that's been marked as item 52 and that is the rear driver's side of the squad car. >> and can you describe for the jurors, well, let's move on to 174 and then describe for the jurors what item 52 is. >> this was a closer photograph of item 52. it was a small irregular shaped piece that could have been a portion of a pill. it had that same kind of rough textured appearance as item 51. there was no visible markings on this particular item either. >> was that collected for testing as well? >> it was. >> and then going to exhibit 175. so a little harder to see, but can you describe for the jurors what appear to be marked as items 53 and 54?
10:00 am
>> yes, so in the background of the photograph is an item marked item 53. this was a small piece of what could have been a portion of a pill... everything else that looked like it could have possibly been a piece of pill, small remnants of powder remaining i collected together. >> let's go to exhibit 176, please. and is this a close up then of item 53? >> yes, this is a close-up of item 53 which looked like it could've been a piece of a possible pill, although it was
10:01 am
reddish brown in color. b it was actually stuck to kind of the seatback portion of the rear passenger seat. >> didn't seem consistent with 51 or 52 or 54? >> it did seem consistent except for the color difference. it did still seem consistent with the other pieces. >> was this also retained by you and made available to the lab? >> yes. and, in fact, you had done some testing yourself on these items? >> yes. >> and you had done some dna testing on that, correct? >> yes, i did some dna testing. >> which item did you do dna testing on? >> initially i did my dna testing on eight different bloodstains that were collected from the back seat of the t squ, and then in that same round of dna testing i did collect
10:02 am
samples from two two of the 20-dollar bills that were recovered from the mercedes-benz suv and they did dna testing on those items as well. >> and did you do dna testing on item 51 that we just saw? >> yes. in a subsequent report i i did item 51 as well. >> and did you do dna testing on items 52-54? >> no, did not no, did not. >> why not? >> they were quite small. they were fragile. item 51 was pretty fragile side to collect the sample very carefully. the other ones were too small and fragile and were not conducive for dna testing. item? >> addition to doing dna testing on item 51, i also tested it for the component of your saliva cited that first and it was
10:03 am
positive so i did dna testing on it. >> so without going into great deal of detail about dna testing, what is the general premise behind dna testing? >> dna testing this particular case, i did nuclear dna testing, the type of dna from your mom and half from your dad any combination that makes you different even than your siblings. the dna goes for air hair color, eye color, things you can't necessarily see, essentially your genetic blueprint. we do dna testing on items of evidence from the scene and compare it to dna samples.
10:04 am
>> in what ways can dna be left behind, forensic testing be done? >> dna can be left behind in a variety of ways bodily fluid, something like saliva or blood, dna can be left behind by touching an object or handling an object, it can be found also in the roots of your harris, it can show up in a number of instances. >> when you have an item like item 51 that appears to be a pill, you can test to see if they are in the presence of the saliva? >> yes. >> with that be true even if it appears to be dried? >> it's possible to leave that behind. >> describe for the jurors how you try to determine if there is or has been saliva on an item like that.
10:05 am
>> the pill itself, i swabbed it with two swabs that essentially look like q-tips. each side of the pill together and from the swabs, i took a small cutting of it and used it tested it with the chemical that we use to detect the presence of amylase found in saliva so if it tested positive, it indicates that could possibly be saliva on the particular sample. >> regard to item 51, what did you find? >> it was positive. >> there was amylase indicated, there was a presence of saliva at one time? >> correct. >> did you then conduct dna testing on item 51 to determine swabbing from item 51 to try to determine the source.
10:06 am
>> i did. >> did you conduct dna testing in accordance with the operating procedures and an accredited lab. >> i did. >> did you have a known dna profile for george floyd? >> yes, known dna sample mr. floyd that i previously developed in my first round of testing. >> based on the testing of item 51, what did you find? >> from item 51 collected from the pill, i obtained a dna profile that matches george floyd, the dna profile would not be expected to occur more than once a month, and the population. >> after you did your testing, did you make it available for other sections? >> yes, it was sent to drug chemistry after i was done.
10:07 am
>> i deviated a little from the original search of the squad car processing, i want to go back to may 27 when you first processed the squad car. you mentioned finding apparent blood in the squad car, correct? >> yes. >> what was that located? >> primarily located in the rear passenger side as we will be able. >> exhibit 177 -- 182. >> i have. >> i would offer those. >> 152 received. >> exhibit 177, please. when you are processing a vehicle and you see something that appears to be blood, is there something you can do to determine if it is blood? >> yes, a presumptive blood test we use, we'll take a small
10:08 am
portion of a stain we think is blood and swallowed up and then use a chemical process on that, if tested positive, it will turn pink. if negative, the color will stay unchanged. >> when you are doing that, do tests for each of those? >> yes, for each bloodstain, it would get its own presumptive test. >> we see in the center of this photograph, exhibit 177 mentioned earlier, there are three white text, can you describe those? >> and see item 12, 13 and 14, marking locations of potential bloodstains and also, ph positive means the blood test
10:09 am
performed was positive. >> do you recall how many separate things you collected from the squad car that appeared to be in this area of the squad car? >> in this particular portion, there were four different bloodstains. >> than in other areas? >> on the rear passenger seat, an additional four stains. >> go to exhibit 178. can you describe what we are seeing here? >> exhibit 178, you can see the photograph in the center, and item marked ten with the ph positive marking bloodstains that was positive for the presumptive blood test and this was the rear passenger side, item number 11, a little out of
10:10 am
the photograph more in the door frame of the vehicle and that was positive for the dozens of blood. >> in this photograph exhibit 178, what we see on the left side is what? >> doorframe where the edge of the rear passenger seat on the seat backside. >> exhibit 179. describe this. >> these are two stains on the rear passenger seat bottom postmarked as items 14 and 15 and its ph positive, indicating it tested positive. >> these are the areas where we saw the strap. >> yes, the strap is right next to. >> exhibit 180 describe this. >> item marked item 16, a rear passenger seat back and again,
10:11 am
an area positive for the presence of blood. >> exhibit 181. >> a photograph of the seat back as well, you can see two items stickers, item ten is an area positive for the presence of blood in item 18 is also marking what i believe was possibly a bloodstain. i didn't do presumptive blood test while processing this at the particular time due to how small the stain was. >> finally, exhibit one age two. as been removed and we see other items here. >> correct, after the strap was moved and the four locations on the rear passenger seat were
10:12 am
blood was indicated. >> as we have seen then, there were from my calculations, seven blood like stains, six of which presumptively tested positive? >> there were seventh of presumptively tested positive for blood in a total 88 of eight. >> did you then -- describe where they were generally located in the car. >> rear passenger side of the vehicle. >> did you conduct further -- let me ask this, did you take samples of them back to the bca? >> yes, i collected a sample from each location, they are packaged up individually and
10:13 am
sent for dna testing. >> was dna testing done? >> yes. >> who did that? >> i did the dna testing. >> when you tested each, did you follow standard procedures necessary for your lab? >> i did. >> what was the result. >> all eight locations i obtained a single dna profile, george floyd and again, the dna profile would not be expected to occur more than once in the world population. >> that was george floyd blood. >> yes, essentially. >> i have nothing further. ... >> ten minutes, please.
