Mazak says Mo Wilson's bike was found at the approximate location where Kaitlin's Jeep was parked for about half an hour.
At 9:21, Colin texts Kaitlin. She never responds.
Kaitlin's Jeep travels north on I-35 all the way to HWY 290 before turning around and heading back to South Austin via I-35.
At 9:43pm, Kaitlin's Jeep stops at a dumpster near an apartment complex for three minutes. It then turns and heads home. This is where Kaitlin's phone is once again powered on and goes "on-network."

At 9:54pm, Cash arrives home and calls 911.
Correction: Kaitlin's phone arrives home at 9:47pm. It goes "on-network" at 9:55 pm. Mazak doesn't have a reason why there is a time gap between the two, other than to say it could be for a number of reasons.

Duggan asks if she looked at DNA swabs from Armstrong's jeep. Perkins says no & doesn't know if any DNA was taken from it.
10:59 AM · Nov 14, 2023

Perkins says, "I don't have any information on whether she had previously touched the bike or come in contact" in regards to why there was very strong support Kaitlin Armstrong's DNA was on Moriah Wilson's bike seat by state prosecutor Rickey Jones.
11:04 AM · Nov 14, 2023

Duggan: You can't say that #KaitlinArmstrong's DNA was for sure on bike seat? Perkins: Right. The likelihood ratio is a comparison of two hypothesis, is she a contributor or is she not. the likelihood obtained is indicating that she is a possible contributor.
11:08 AM · Nov 14, 2023

We are on a 1-hour break for lunch. We are finished with witness Perkins, who says there is a very strong likelihood that Kaitlin Armstrong's DNA was on Moriah Wilson's bike seat.
11:21 AM · Nov 14, 2023

 

[Howl]

Sounds like Cash’s apartment and Deep Eddy is only about 10-15 mins away

Strictly depends on time of day and traffic, although things should be relatively settled down by 8 or 8:30 pm.
You've got to get across downtown on surface streets somehow, navigating mucho traffic lights whichever way you go. A lot of people use WAZE navigation app to sort out which of multiple routes is fastest.

 

[Maat99]

Is this when the defense asks who else may have had access to KAs phone? Because someone would have needed to take her car and her gun and her phone. They can’t even really dispute the gps data because she is also on video.

I wonder if she was going to steal the bike to make it look like a robbery, but then changed her mind or was interrupted before attaching it to her car rack, and just dumped it in the bamboo thicket.

I think this is the part where Cofer says...defense rests....

Early tweets before lunch recess:

Next witness, you guessed it, Samantha Perkins.

Perkins, DNA supervisor and technical leader, Texas DPS. Has held position for six years. Responsible for DNA operations of lab. She has had specialized training in molecular biology, statistics and other physical sciences.


The courtroom is being shown a PowerPoint presentation of the results of the DNA analysis.The first slide explains what DNA is: how it is genetic instructions that code everything in our bodies from how they function to what we look like. ~1% is highly different from other individuals, which is what an analyst is interested in.


DNA Analysis four steps: Extraction, quantitation, amplification and detection-generation/interpretation of a DNA profile. Perkins is going through each of the four steps.

Perkins says they use STRmix Software to interpret a DNA profile. Perkins says she looks at every location to determine if the sample contributes to the profile or if it should be excluded. The software helps interpret the mix, deconvolute the profile and compare reference samples, performing a statistical calculation called "likelihood ratio" to provide weight to the evidence.


Likelihood Ratio is two conditional probabilities:1) Prosecution's hypothesis: DNA came from a suspect in the case 2) Defense's hypothesis: The DNA came from an unrelated, unknown individual (not the suspect)



Perkins says that DNA profiles are never a 100% match. The highest likelihood that a DNA match exists to a subject uses nationally recognized language of "very strong support.”


We are now looking at the reports that Perkins created regarding the DNA profiles. First submission: Swabs from handlebars of bicycle. DNA profile has three contributer matches. Mo Wilson, Kaitlin Armstrong and one unrelated individual. Kaitlin Armstrong is considered a possible contributor to the profile. Probability of Colin Strickland and Caitlin Cash is excluded.


Based on the chart we were looking at, there is "strong support" that Kaitlin Armstrong's DNA is a match on the bicycle handlebars.


2nd Submission: Swabs from seat of bicycle. Mixture of three individuals including Mo Wilson. Also two unrelate individuals. Kailtin Armstrong is a possible contributor for the profile. "Very strong support" it is Armstrong's DNA. There is no higher likelihood than "very strong support." Cash and Strickland have been excluded.



3rd Submission: Swabs from firearm grip, trigger, trigger guard, safety, magazine release and slide serrations. DNA profile obtained could match three individuals. Kaitlin Armstrong and Colin Strickland are possible contributors. Cash and Mo Wilson are excluded. Armstrong's DNA likelihood is 3.87 septillion times greater than the probability that this profile came from unrelated, unknown individuals.


4th submission: Swabs from magazine base and loading port. No interpretable DNA profile obtained.

5th & 6th: The saliva standards for Armstrong and Wilson were used for comparison purposes.

7th: Swabs from from underside of bicycle seat. No interpretable DNA profile obtained.

8th: swabs from exterior of gum wrapper. No DNA profile obtained.

9th: Saliva from Colin Strickland used for comparison purposes.

10th: Saliva from Caitlin Cash used for comparison purposes.

11th: Swabs of stain on floor. DNA profile matches Mo Wilson. Armstrong, Strickland, Cash were all excluded as possible matches of blood on floor.




Witness passed.



--- Defense's turn. Perkins says she interpreted the DNA in this case. Defense pushes that DNA does not tell when or how the DNA got to an eventual location, just that it exists.Swabs were only taken from the Sig Sauer firearm, not the Springfield, says Perkins.


Defense asking about the firearm testing, which shows that there could have been three possible contributors. Armstrong, Strickland and a third unknown profile. That third profile showed a Y chromosome, indicating male DNA. It is impossible to say who the unknown contributor is.


Defense asking about trace and transfer DNA. Perkins going through how some people shed skin cells more than others. "Good Shedders vs. Bad Shedders" is the term Perkins uses.


Perkins says that because the trigger, trigger guard, magazine, etc. were all apart of the same swab, you cannot differentiate where on the gun the DNA was pulled from.


Defense hypothesizing about the potential transfer of DNA on non-tested items, like motorcycle helmet, face guard, chin strap, etc. Perkins says DNA would likely be found on all those things. Defense concludes that via transfer, it's possible for someone's DNA to exist in a place where they have never actually been.


Defense keeps ensuring the jury knows that Perkins cannot say that Armstrong's DNA was definitively on the bike. Only that there is a "strong likelihood" that Armstrong's DNA was on the bike.


No further questions.

The court will take a one hour break for lunch. I'll have a new afternoon thread when we return.

KAITLIN ARMSTRONG AFTERNOON THREAD


This morning we heard from a DNA analyst who said it was highly likely that Armstrong's DNA was found on Mo Wilson's bike at the crime scene. A medical examiner showed us pictures of the gunshot wounds Wilson sustained. Live tweets below.


Next Witness: Pamela Mazak, Criminal Intelligence Analyst, Cold Case and Missing Persons Unit, Texas Attorney General's Office.Former APD Crime Analyst for 20 years.


Mazak helped detectives analyze the cell phones and extraction data. She also looked at the Jeep infotainment system. We are going to look at call detail records.

Because the cell phone records are so voluminous, it is too difficult for the witness to easily explain to a jury. For that reason, it appears we are going to instead look at a PowerPoint presentation that Mazak created.


This PowerPoint presentation was altered on Nov. 10, 2023. A previous version was discoverable and given to the defense for review. There is a sidebar happening with the Judge now; I suspect because this version was not made available to the defense with enough time to review.


Sidebar over. The PowerPoint has been admitted into evidence without objection. We are now about to view it.
Presentation: Methodology was using databases from cell phone companies. Call Detail Records document the network interactions to and from the cellphone, including date, time, duration, number called and calling number. CDRs use cell towers to pinpoint cell placement.



Cells are considered radios that scan the cellular network looking for the best signal from the cell sites. It is often the closest cell site, but not always. Various factors affect signal quality.


The location of cell towers are often determined by population and anticipated capacity/use. Generally, there are more cell towers with partial overlapping coverage in urban areas and less cell towers in rural areas.


We are looking at Kaitlin Armstrong's cell records, received from Verizon. Phone was disconnected on 5/16/22.Mazak was asked to analyze Armstrong's data from 9/1/21-5/15/22.Location information is provided for calls only, location information is NOT provided for texts.


Before going into the mapping, Mazak is also sharing that she looked at the cell phone data of Strickland and Mo Wilson, as well. Armstrong's data will be mapped in yellow, Strickland's in blue, Wilson's in green. Only mapping locations with accuracy of <= 200 meters.


The locations of interest: Fort Clarke Home, Deep Eddy Pool, Pool Burger Bar and crime scene in East Austin.


There is now a timeline of Kaitlin, Colin and Mo's communication on 10/28/21. Kaitlin and Colin text back and forth, including the text: "I know you know better than to show up at Meteor with that girl." There is a phone call from Kaitlin to Colin. Kaitlin also calls Mo at 6:34 pm. That call lasts 1 minute and 28 seconds. At 6:41 pm, Kaitlin calls her sister Christine Armstrong and speaks to her for 23 minutes.



Later on at 6:53pm, Colin responds to Kaitlin. "Could you please be an adult?" Later, "Mo left for Meteor with friends an hour ago. I am not going because I am trying to respect you"... "Yet, I'm not feeling respect from you." Kaitlin responds: "Not the best feeling is it." Colin: "Yeah, you sure are paying it back.”



About an hour and a half after Kaitlin's phone calls Mo's phone, Colin texts Kaitlin: "Did you call Mo? Wtf?""Sorry, I can't talk right now," is the response.



About an hour and a half after Kaitlin's phone calls Mo's phone, Colin texts Kaitlin: "Did you call Mo? Wtf?""Sorry, I can't talk right now," is the response.



We are now fast forwarding to May 9 & May 10, 2022.Kaitlin's phone views Mo's Strava profile once on 5/9/22 and four times on 5/10/22. Mo Wilson arrived in Austin at 4:47pm on 5/10/22.



On 5/11/22, the day of the murder, Mo texts Colin at 9:01am: "Whatcha thinking?" Kaitlin and Colin's phone records show an arc location that most likely means they were at home. Mazak says it is hard to be precise with location data. Mo's location is likely Cash's apartment.



Kaitlin and Colin's phones leave home for a morning bike ride around 9:00am. Mo texts Colin for the first time of the day one minute later.Colin's phone continues to Lockhart while Kaitlin's turns around and heads home. This path matches her Strava activity of the day.



Colin responds to Mo at 11:12 am after returning from his bike ride: "I rolled out early with my buddy...I never heard from you!"Moriah wonders if the two are having phone troubles again. In reality, the phone issues of the past were likely a result of her phone number being blocked without either of them realizing it.


At 12:41pm, Mo texts Colin: "Do you have plans tonight? Cash has a dinner with some college friends who are visiting so I'm on my own." At 1:31pm, Mo goes on her own bike ride.



Colin to Mo at 3:15pm: "Want to go swimming? Maybe swimming and a beverage."Kaitlin's jeep begins leaving their home area shortly after Colin's phone arrives back home. Kaitlin's Jeep and phone travel to S Lamar Blvd and stop around 2:07pm. That's the last location of the Jeep for over an hour.


Colin's texts about swimming plans happen around the same time he arrives to his dentist at 2:30pm. Mo is still on her bike ride at this time. Kaitlin's Jeep is now heading downtown. At 3:41pm, Colin follows up with Mo: "What do you think?" Mo agrees.



At the dentist, Colin finalizes plans to pick Mo up after her bike ride on his motorcycle. Kaitlin arrives back home at 4:13pm. Her cellphone location data is being corroborated by her Jeep infotainment location data.


Kaitlin and Colin speak over the phone at 4:24pm. They speak for 3 minutes and 4 seconds. Colin is still at his dentist appointment. Gotta wonder what that discussion was like. At 4:31pm, Mo tells Colin she got back and he can come and pick her up at Cash’s.


Kaitlin sends Colin a series of texts about real estate deals at the same time he is texting Mo. Simultaneously, Mo texts Colin Cash's address for him to come pick her up.Kaitlin begins to view Mo's Strava profile and activity at this time. She looks at her specific route and starting/ending point to view the map.


Cash leaves home at 5:30pm. Colin arrives to pick up Mo up at around 5:40pm. Mo locks the door of Cash's apartment behind her at 5:55pm. Mo & Colin's phones move together away from Cash's home, arriving at Deep Eddy at 6:09pm.


During this entire time, Kaitlin has remained at home through 6:15pm. Kaitlin calls Colin at 6:24pm. No answer. Kaitlin texts Colin. No response. Colin is at Deep Eddy this entire time. Around 6:57pm, the two head to Pool Burger.


Around 6:33pm, Kaitlin's jeep leaves home and heads down South Lamar. Jeep stays in one location until 6:54pm.Alex Note: Mazak's presentation is really well done. In addition to being informative, it is interactive and corroborates all of the facts with other evidence the prosecution has presented, including maps, receipts and still images. It is is really easy for a jury member to follow along to get the full picture.


Kaitlin's Jeep moves north on South Lamar around 7:15. She has not received any replies from Colin. We are watching an animation now of Kaitlin's Jeep traveling North on Lamar. It crosses Lady Bird Lake into Downtown around 7:20pm. The cell and Jeep data corroborate each other.


Kaitlin's Jeep takes a series of turns through downtown over the next 10ish minutes.At 7:30pm, the phone goes "off-network" meaning the network can no longer communicate with the phone.


The next time Kaitlin's phone would go "on-network" would be 9:55pm. Kaitlin's Jeep, however, continues to provide location information.Kaitlin heads east to I-35, North on Frontage Road, and then East on MLK toward Cash's place. The jeep circles the block twice using the alleys around Cash's apartment before stopping on a nearby road.


Kaitlin's Jeep is spotted on various video surveillance systems near Maple Ave. at 8:05pm, 8:06pm, 8:08pm. This video is corroborated by the Jeep infotainment data. The jury is reminded with still images from each of these video systems.



Colin and Mo leave the Deep Eddy/Pool Burger area at ~8:16pm. Video surveillance confirms cell phone data.Colin and Mo arrive back at Cash's around 8:28pm. The Jeep is seen around 8:26pm on video surveillance just a few doors down.


At exactly the same time, 8:28pm, all three phones are all within a few hundred feet from each other. The courtroom is enraptured by the drama and storyline that this map is providing. Everyone's eyes are glued to the closest screen.


8:29pm, Colin and Mo arrive at Cash's. The Black Jeep is stationary on the side of the street for 3.5 minutes. At 8;35, Colin's phone moves North while Mo's stays at Cash's. Colin's motorcycle is seen riding away on surveillance video. At 8:36pm, Colin texts Kaitlin his false alibi. Mo Wilson unlocks Cash's door.


At 8:37, the Jeep is seen traveling westbound in the alley next to the apartment where Mo was staying. A still image of the Jeep from the video pops up for the jury to see and remember.


Mo Wilson begins using phone apps within a few minutes of being dropped off. The Jeep pulls out of the alley and parks at 8:41pm. It doesn't move until 9:17 pm. Colin's phone shows that he arrives back home at 8:50pm.


At 9:07pm, Colin receives an incoming call from Allan Burrows that lasts 9 minutes. Cell phone data shows that he is home when he receives this call.At 9:13pm, Mo would send her final text message. At 9:16pm, a woman's screams can be heard and three gunshots. The full audio of that moment was played with a loud speaker for the jury to hear.


Mazak says Mo Wilson's bike was found at the approximate location where Kaitlin's Jeep was parked for about half an hour. At 9:21, Colin texts Kaitlin. She never responds. Kaitlin's Jeep travels north on I-35 all the way to HWY 290 before turning around and heading back to South Austin via I-35. At 9:43pm, Kaitlin's Jeep stops at a dumpster near an apartment complex for three minutes. It then turns and heads home. This is where Kaitlin's phone is once again powered on and goes "on-network.”


At 9:54pm, Cash arrives home and calls 911.Correction: Kaitlin's phone arrives home at 9:47pm. It goes "on-network" at 9:55 pm. Mazak doesn't have a reason why there is a time gap between the two, other than to say it could be for a number of reasons.



State has no further questions. Defense's turn. But first. a 10 minute recess!

 

[Maat99]

What do people think KA discarded in the apartment dumpster? Some sort of covering for her clothing? Gloves?

 

[knla]

I wonder if she was going to steal the bike to make it look like a robbery, but then changed her mind or was interrupted before attaching it to her car rack, and just dumped it in the bamboo thicket.

She may have taken the bike to get away from the scene faster.

 

[jash]

You're back, @arielilane ! *tossing reins to Alex's thread back to you*

 

[Howl]

CS testified that nobody outside of the industry would recognize the value of MW's top of the line bike -- a tool of the trade.

True, but Austin has a staggering and brazen bike theft problem

Spoiler: More than you want to know about bike theft in Austin!

-- locked bikes robbed off a car's bike rack, out of garages, from bike racks in front of businesses and schools, from apartment balconies, from inside houses and storage units and sheds.
If thieves have been following a car with bikes, for example, the theft could take place in the few minutes someone went inside before unloading their bikes. There are random thieves stealing as a crime of opportunity as well as organized gangs that steal bikes, and move them down I 35 to sell in Mexico. Those people definitely know a bike's value. Remember, the Mexican border is less than five hours from Austin.
Alternately, the bike can be stripped down and the frame and components sold separately on line.

Defense Questioning:Mazak discussing how cell towers determine time and location of cellphones. It is reliable for getting general locations, but not precise locations. Mazak admits there is nothing in the presentation, records or analysis that definitively says that Kaitlin Armstrong was driving the Jeep or using her phone during that entire time.

12:13 PM · Nov 14, 2023

Defense objects to Mazak being an expert witness. Judge Kennedy objects. We are now being shown the powerpoint. Cell phone companies maintain databases on costumers related to usage of cellphone. CDR: call detail records document network interactions to & from cell phone
12:22 PM · Nov 14, 2023

CDRs capture cell tower (cell site) and cell sector when contact was initiated with network. Analysis is performed on CDRs obtained for cell #'s of interest. Cell phones are radios that use radio frequencies to communicate. constantly scan network looking for best signal

BACK TO TODAY
At 4:10PM, we are taking a break. When we come back it will be defense' turn to ask Mazak questions.
2:10 PM · Nov 14, 2023

Defense Attorney Jeremy Sylestine up asking Mazak questions.
Mazak says RTT is estimating the distance from the cell phone to tower based off how long it took radio signal to go from phone to tower.
2:40 PM · Nov 14, 2023

S: Nothing about your presentation that definitely shows KA was driving jeep on 5/1/22?

Mazak: That's correct. Says it's correct that she can't say for certain Kaitlin Armstrong was using her phone that day.

Sylestine says data doesn't show any 1 person was using phone, jeep
2:43 PM · Nov 14, 2023

Sylestine offers court exhibit titled, "Verizon Wireless RTT Report and Round Trip Delay Disclaimer."

Says RTT data are best estimates and are not related to any GPS measurements.....best estimates rather than precise locations for phones.

Mazak often spoke about how she corroborated her data and time stamps between two or more sources. Think: Cell data and Jeep data. Defense questioning how accurate the time stamps could be and how the data was inputted in the animations that were shown to the jury.

@alcaprari23

Defense asking if Mazak is ever asked for input on how detectives should investigate their cases. Mazak agrees that happens sometimes. Mazak says in this case there was a lot of data to comb through, and she helped detectives and the DA narrow down what is most relevant.
