00:01She's laying on the floor and there's blood everywhere.
00:06There's a showcasing right here next to my right knee.
00:08Tonight we're learning the victim of a deadly shooting in East Austin was a well-known cyclist.
00:13The idea that the killer stood over her is just chilling to me, chilling.
00:17Last night she passed away.
00:20This could have been the last person to see the victim alive.
00:24A lot of people in the community believe that he was quite the playboy.
00:27Immediately when I walk in, very, very cold, heartless, blank stare.
00:32There really are no winners here. This is a time for prayer.
00:35The suspects' whereabouts were completely unknown.
00:39I remember thinking, like, innocent people don't run away.
01:13I heard this story on the news and what really struck me was this really amazing cyclist getting murdered in
01:20cold blood.
01:21There were so many bizarre elements to this case.
01:25And the case kept escalating.
01:27It was like a real mystery at first about what happened to her.
01:31And it turns out it's about sex, betrayal, jealousy and murder.
01:39In 2022, Anna Mariah Wilson is 25 years old and known to her friends and family as Mo.
01:45She's a single woman and an up-and-coming professional cyclist living in San Francisco.
01:50We're joined with Mariah Wilson.
01:52You came down from Northern California.
01:54What do you think so far?
01:56The course seems sweet.
01:57It's great. I'm stoked to be here.
02:00Mariah grew up in Vermont and she went to Dartmouth.
02:04She was this incredible athlete pretty much her entire life.
02:09I spoke to one of her high school friends and she had said that Mo was the type of athlete
02:13that it was really all about, like, the camaraderie.
02:16She was just so encouraging to everyone.
02:19She was very outgoing and had a bubbly personality.
02:22She kind of lifted the people up around her.
02:25She came from a family of athletes.
02:27Her father was on the U.S. ski team.
02:30She wanted to be an Olympic Alpine skier.
02:32But unfortunately, she had a number of ACL injuries.
02:36Being in Vermont, you're skiing during the winter.
02:38And then in the summer, it's typical for those trails to still be open without snow for bike races.
02:45And so when she got injured, she ended up switching over to gravel racing.
02:49Gravel racing is, it's almost like an extreme sport.
02:53They're not just doing a regular cycling, like, in the neighborhood or anything like that.
02:57They're out in the mountains.
02:58They're going up and down these huge hills.
03:01And you're doing it at really fast paces.
03:04You enjoy the climbs.
03:06Yes.
03:06You enjoy a 10,000-foot day.
03:07Yes.
03:08I probably won't be thinking that when I'm out there riding tomorrow.
03:11Yeah.
03:12Immediately after picking up gravel racing, she started winning races.
03:16She was deemed as being one of the best in the U.S.
03:19Every race that she would compete in, she would win.
03:22But not only just win, she would win by a lot.
03:25Mo Wilson, phenomenal race. Congratulations, first of all.
03:28Thank you so much.
03:29I cannot wait to see what you're able to do at the next stop in Emporia.
03:33And I hope you can just really soak up this win.
03:35In May of 2022, just before her 26th birthday, Mo goes to Texas to participate in the gravel local road
03:43race.
03:43It's a 157-mile bike race.
03:47She stops in Austin for a couple of days to visit friends before heading to Heiko.
03:51But in a dark twist of fate, her weekend trip turns into a nightmare.
03:58Austin 9-1-1.
04:00Um, my friend is staying with me and I just walked in and she's laying on the bathroom floor and
04:07there's blood everywhere.
04:09Um, and I don't, I don't know what happened.
04:13Okay.
04:14Is she awake?
04:15She's not awake.
04:16There's blood all over her face and all on the back of her head.
04:19Is she breathing?
04:25No.
04:30Austin, please.
04:40Do I stop?
04:41I don't know what happened.
04:43I just walked in on her.
04:45Okay.
04:52There's a shell casing right here.
04:54There's a shell casing right here next to my right knee.
04:56Okay.
04:56Pause this second bite.
05:02Is that just an exit?
05:05Nobody heard any shots?
05:06We don't know how long she's been down?
05:08No.
05:09All right.
05:10Did we call that?
05:11Yeah.
05:11Okay.
05:13She was pronounced deceased.
05:14So, officers immediately call the Austin Police Department Homicide Unit.
05:18While the patrolmen wait for homicide to arrive, they talk with the 911 caller who resides at the apartment and
05:24is friends with the victim.
05:25Her name was Kaitlyn Cash.
05:27She goes by Cash.
05:29Is your friend of mine?
05:31No.
05:32She doesn't live here.
05:34Here you go.
05:35Here you go.
05:37Take a breath.
05:39Do you know if he's talking to anyone or any friends?
05:42I know you say you don't even live here.
05:43Yeah, I know.
05:44She was with her friend Collin.
05:46Collin?
05:46Yeah.
05:47What was that?
05:48Collin Strickland.
05:49Did you see a gun or anything like that in your way?
05:52No.
05:52No.
05:54No.
05:55She seemed distraught.
05:57She was very concerned for her friend and she was very forthcoming about information to try and help.
06:01What's her name?
06:03Her name is Mariah, M-O-R-I-A-H Wilson.
06:09We learned that her real name is Anna Mariah Wilson, but she actually goes by Mariah and most of her
06:15friends actually refer to her as Mo.
06:17She came to visit you.
06:19Yeah.
06:19She's here for a bike race this weekend.
06:22Oh, yeah.
06:22Did her and Collins have an argument at all, do you know?
06:24I don't have, I don't have any idea.
06:27Caitlin Cash is taken to the station while homicide detective Tim Price is notified that he's caught a case.
06:34So when I arrived at the scene, the patrol officers that had already responded had taped off the crime scene.
06:40They had the entrances and exits to the alley sealed off.
06:44Looking at the apartment from the alleyway, it looked very normal.
06:49I didn't see anything from outside that led me to believe that somebody had forced their way into the apartment.
06:56Inside the apartment, all the possibilities are going through my mind.
07:00Is this some type of burglary or robbery, an attempted assault?
07:04You could see the victim from the front door.
07:07About half her body was sticking outside of the bathroom area.
07:11She did have what appeared to be gunshot wounds.
07:14There are two gunshots to the victim's face and blood surrounds her head and neck.
07:20We noticed two fired cartridge cases in the kitchen area.
07:24So it appeared from first glance that somebody had stood near the doorway and possibly shot the victim from a
07:32few feet away.
07:32We collected those cartridge cases and both of them were 9mm rounds.
07:39We can try to match those cases if we end up recovering a firearm while working the case.
07:45Then police discover a third gunshot wound and a bullet.
07:49And the bullet actually went right through her and wedged itself into the floor.
07:56The only way to receive that type of injury is for a person to stand directly over that person and
08:01shoot them.
08:03That was just a very cold-blooded, evil thing to do.
08:10To shoot somebody, then to walk across and stand over them and shoot them again.
08:14The killer wanted to make sure that the victim was dead.
08:19Whoever did this, it was a very personal act.
08:23I believe that most likely the suspect knew the victim.
08:27It was an execution-style killing. Somebody wanted her dead.
08:31The question was, why? Why would somebody want this young cyclist dead?
08:37Cash told us that Mariah met up with an individual named Colin Strickland that night.
08:42She was with her friend, Colin Strickland.
08:48He potentially could be a suspect, so it was extremely important to locate Colin.
08:54Yeah, they went swimming.
08:56If he was the last person to see her alive, we needed to talk to this guy right away.
09:01All the way down. This is him.
09:14You have a seat right here on this white chair right here. The detective is going to come and talk
09:19to you.
09:19In the homicide office, Cash indicated that Mariah didn't really know many people in the Austin area.
09:25The only other person she knows is Colin Strickland, who she was supposed to be meeting tonight.
09:33Colin Strickland was another really well-known gravel racer that was kind of a celebrity in that realm of the
09:41cycling community.
09:43Colin Strickland is a 35-year-old cyclist. He had a lot of sponsors, but he wasn't winning as many
09:49races as he had when he was younger.
09:51A lot of people in the community believe that he was, you know, quite the playboy.
09:56When she was here in the fall, she did stay with him for a couple of days.
10:01Okay.
10:02And they, I think, were sleeping together.
10:05Yeah.
10:06And then they broke things off, pretty much.
10:11Okay.
10:11Their relationship was only about a week.
10:14And this was back in October.
10:17They were still communicating every now and then.
10:19But at this point, they were just friends.
10:23Cash was able to give us a pretty good timeline of what took place the night before.
10:29Cash told Mariah that she was going to be out with other friends.
10:32Cash ended up leaving, and Mariah was still at the house.
10:36What were her plans for tonight?
10:39She's going to go swimming with Colin.
10:42Cash arrived back to the apartment around 9.55 p.m.
10:46The doors closed, but it was unlocked.
10:49I walked in, and I could see her feet sticking out of the bathroom.
10:57And that's when Cash saw that Mariah was unresponsive and was bleeding.
11:04Although Caitlin Cash wasn't home most of the night, she knew when her front door was locked or unlocked.
11:09I have a keypad entry code.
11:11Okay.
11:12And it will tell you exactly what time I was unlocked.
11:15Yeah.
11:15And locked on my phone.
11:17I have an app.
11:18Cash was able to tell me that Mariah had locked the door at 5.55 p.m. when she was
11:24leaving.
11:26Cash then got an alert at 8.36 p.m. indicating that the door was unlocked, and Mariah had probably
11:33just arrived home.
11:38This told me that the murder had to have occurred somewhere between 8.36 p.m. and 9.55 p
11:44.m.
11:46Cash also told us that Mariah's bike was missing.
11:50Her bike was not inside.
11:52Under normal circumstances, she wouldn't have brought her bike upstairs and be sitting by the front door.
11:58I told that to the deputies at the crime scene.
12:01Is there a bike?
12:03Anywhere?
12:03Do you see a bike?
12:04No bike.
12:05No bike.
12:06It was a really expensive bike.
12:08And so police wondered, you know, is robbery the motive here?
12:12Detectives at the crime scene began canvassing the area looking for surveillance video, witnesses, and any evidence that could have
12:20been left behind.
12:22While canvassing the neighborhood, one of the patrol officers located a bicycle down the alleyway from the apartment.
12:28It appeared that it had been thrown into some bushes.
12:34I did know right away that we wanted that bicycle preserved until we could collect it, swab it for Prance
12:40DNA.
12:41I Googled the brand of the bicycle and learned that it was probably a $10,000 or $12,000 professional
12:47racing bike.
12:48Detectives wondered, like, why wouldn't you take a $12,000 bicycle? Why would you just discard it?
12:54I felt after observing that, that a property crime wasn't at play here, that somebody didn't come in here to
13:01steal some stuff.
13:02Then the neighborhood canvas also produces another lead.
13:05We did find one resident probably about 15 feet from where the stairs go up to the apartment who had
13:12video footage from their front door.
13:14And so we're really zoned in on video from about 8 p.m. to approximately 9.50 p.m.
13:21That's when detectives spot a suspicious vehicle driving by repeatedly on the street near Caitlin Cash's apartment.
13:28It was a dark-colored SUV. It appeared to be a Jeep.
13:32The Jeep Cherokee has a luggage rack on the top, but also a bicycle rack on the back, and then
13:39chrome windows.
13:41The driver didn't appear to be driving like they were going somewhere.
13:45We could see that they kept stopping and slowing down. So that stuck out right away.
13:49Unfortunately, what they don't see is the driver of the vehicle or the license plate because the bicycle rack is
13:57covering the license plate numbers.
13:59That resident also had a camera that faced the alleyway.
14:04At 8.37 p.m., this black SUV begins slowing down, almost coming to a stop, right next to the
14:11door of Cash's apartment.
14:13This is one minute after Mariah had just walked inside.
14:21As dawn approaches, the next order of business is speaking to the last person who potentially saw Mariah alive, Colin
14:28Strickland.
14:30When officers arrived to Colin's house, they notified me that there was a black SUV in the driveway.
14:36It had a luggage rack on the roof, it had chrome around the windows, and it had a large bike
14:42rack that was mounted onto the back trailer hitch.
14:44This vehicle matched the exact description of what I had seen on video surveillance one minute after Mariah had entered
14:52into her residence.
14:53At this point, we're starting to think we might actually have our suspect. This might be our guy.
14:59I thought maybe Colin had gotten into a fight with Mariah.
15:03And after he dropped Mariah off, he couldn't get over this argument, circled around the block, and then returned to
15:09Cash's apartment.
15:11Suspicious of Colin Strickland from the get-go, detectives want to see how he reacts to the news of her
15:16death.
15:17Detective Spittler finds Colin working in his garage.
15:21Hey, so, Colin, who's the first name?
15:24Yes.
15:24Do you know Bo?
15:26The gravel rider?
15:28Yes, I do.
15:28Okay.
15:29We went to the deep Eddie yesterday afternoon, and then they drove her.
15:36And they dropped her at her apartment she's been staying at.
15:40We should really know he's going to say this, so apparently last night she passed away.
15:48How did it happen?
15:50How did it happen?
15:50She, right now it's an open investigation, but it is being investigated as a homicide.
16:00Okay.
16:01Okay.
16:06I don't know.
16:08It's wild.
16:11He was definitely a person of interest at that point.
16:14So he was brought into the homicide office for an interview.
16:18During Colin's interview, he stated that he knew Mo from the cycling world.
16:22He seemed to speak really highly of her.
16:25She's probably the most talented rider in the U.S.
16:29You know, we had a little fling in October.
16:31Last fall, Mo came to Austin for a week after a race, and she stayed at my place.
16:37And my girlfriend and I had been broken up.
16:40Colin indicates that he lives with his girlfriend, Kaitlyn Armstrong.
16:43But the couple was on a break in the fall when he was sleeping with Mariah.
16:47While you were dating Mo, Kaitlyn was still living with you?
16:51Um, she was moving out.
16:53It was definitely very...
16:54I was about to say, that would probably be pretty...
16:57It definitely was.
16:58...awkward.
16:59Him and Kaitlyn got back together a few months later, but he was still talking to Mo.
17:04It did seem that he was maybe playing both sides.
17:08After learning about Colin's complicated relationship with both Kaitlyn and Mo, Detective Spitler turns the conversation back to the night
17:16of the murder.
17:17We went down to the motorcycle.
17:19She got the helmet that we rode to Deep Eddy.
17:21Mm-hmm.
17:22We went swimming for about 30 minutes to 40 minutes.
17:26And then we just walked Pool Burger as adjacent to it.
17:31Colin tells Detective Spitler that they wrapped up at Pool Burger around 8 p.m.
17:35We got back on the motorcycle in the Deep Eddy parking lot.
17:40While this interview was ongoing, officers were able to locate video from Pool Burger indicating that Colin's story about him
17:48and Mariah at Pool Burger was actually correct.
17:51We left Pool Burger.
17:52We drove, and I went up the...
17:54Took Jessalyn and went up the back alley and stopped right at the base of a staircase that goes up
18:01to the place she's staying.
18:03Colin Strickland told detectives that he dropped her off around 8.30, and that was it.
18:09Colin indicated that he had been messaging Mariah throughout the day.
18:13I asked Colin if I could see those messages.
18:15What I found interesting, though, the messages weren't from Mariah, but it was from someone named Christine.
18:22I asked Colin about this.
18:24I haven't saved us a different name just because...
18:27I gotcha.
18:28He said it was Christine.
18:29I feel the right to have a friendship with this person...
18:33Of course.
18:33...without constant strife.
18:36Colin said to them that his girlfriend, Caitlin Armstrong, was very jealous.
18:41I know, back in October, Caitlin went through my phone.
18:44He said that anytime that he speaks with Mariah, that Caitlin would become angry.
18:50In the interview, Colin is trying to show that there's some jealousy issues on Caitlin's side.
18:56Basically, nobody else can handle you.
18:58Yeah.
18:58But there's also the question of whether or not Colin was starting to get in too deep,
19:04and maybe something happened and he needed to get rid of Mariah.
19:17Caitlin and I have a lot of intertwined lives.
19:20Yeah.
19:21We have a business together specifically.
19:24She's been living in my house.
19:26When Colin started talking about Caitlin Armstrong, he didn't talk about her in kind of a way
19:32that you would typically think a boyfriend would talk about their girlfriend.
19:35She's super helpful to have around, but I kind of feel like I'd be better business partners and friends.
19:42Colin tells police in addition to running and operating an RV renovation business together,
19:48Caitlin Armstrong also works in finance and real estate, and she teaches yoga on the side.
19:53They've been together for a couple of years, but Caitlin has a jealous side.
19:58We learned at one point that after the relationship that him and Mariah had,
20:04that Caitlin had actually called Mariah and told her to stay away.
20:09Lode told me, like, this random person called me who says she's living in your house.
20:15Mariah was shocked.
20:16I don't think Mariah knew that Caitlin and Colin were back together.
20:23Then detectives asked Colin Strickland about the Jeep that they find in his driveway.
20:29Whenever I was over there earlier, I saw there was the other car, because you said that you drive a
20:33motorcycle.
20:33I guess the other one is...
20:34The Jeep is hers.
20:35Okay, so that belongs to her.
20:36Okay.
20:37Do you ever drive that one?
20:38No.
20:38I'm thinking he's distanced himself from the Jeep.
20:42He's trying to demean her or speak poorly of her.
20:45Is he trying to possibly pin it on Caitlin?
20:51I told Colin that there was video showing Caitlin's Jeep in the neighborhood.
20:56I know for a fact that her vehicle was at that apartment.
21:15It's a lot to take in.
21:17It's completely happening.
21:23I'll wake up.
21:25Do you own any firearms or anything like that?
21:34I bought a pistol last fall, and I actually never shot it.
21:40What type of gun was that?
21:43I believe it's a 9mm.
21:48This raised some red flags because the casings and cartridges at the crime scene were also 9mm.
21:55Are there any other firearms?
21:57There's two pistols.
21:59Where is the other pistol?
22:06He stated that he had bought two guns a few months before.
22:10One of them was his, and he had given one of them to Caitlin.
22:15So Caitlin has a pistol?
22:17A pistol purchased for her.
22:19It's a Sig Sauer.
22:22It's also a 9mm.
22:25I started thinking, okay, who's Caitlin Armstrong?
22:28What does she have to do with this?
22:29We're going to need to talk to her as well.
22:34She's brought in.
22:35They place her in the interrogation room.
22:37My partner is actually talking to Colin right now.
22:40Caitlin's boyfriend was brought in hours before about a homicide investigation,
22:44and she's not asking any questions about Colin, which was odd to us.
22:51I asked her, have you heard what happened in the past 24 hours?
22:56Colin walked in the house and said one of the women in the cycling community passed away.
23:00Yeah.
23:01While Colin was talking to us, your name came up.
23:06I think you'll see what people that are innocent, they're asking a lot of questions.
23:11Right.
23:11What am I doing here?
23:12Why am I talking to you?
23:13I want to get your side of it, okay?
23:16Because there's always two parts of it.
23:22Um, okay, I'm not sure exactly what you mean.
23:26If you're guilty, you're probably going to sit there and say nothing.
23:29Yeah.
23:29She just sat there and would barely say anything to you.
23:32Colin's been maybe talking to this girl for a little bit, and it sounds like from what
23:37he's saying that you were a little upset about it.
23:41I feel like I should have an attorney present.
23:45You could tell she was, she was done.
23:48She wanted to, to get out of that room.
23:50So at that point, I kind of throw out this Hail Mary.
23:54Your vehicle was the scene next to her house.
23:58That, that kind of makes it look not too good, right?
24:02She doesn't make any denials.
24:05She doesn't explain why her vehicle was over there.
24:08And that was the turning point of the interview that I was like,
24:11okay, we are on the right track.
24:13This was 100% her vehicle.
24:15There's no doubt in my mind at this point.
24:18I would like to leave if I'm free to leave.
24:21Okay.
24:24At this point, Katelyn and Colin are both suspects.
24:26So Detective Connor collects their phones while Detective Price gets a warrant
24:31to search their house.
24:32At the residence, detectives found two non-millimeter handguns,
24:37and both of them were seized as evidence.
24:40That morning, news breaks that Mo Wilson has been murdered.
24:44Tonight, we're learning the victim of a deadly shooting in East Austin
24:47earlier this week was a well-known cyclist.
24:5025-year-old Mariah Wilson was shot multiple times late Wednesday night.
25:00The cycling community was devastated when they found out about Mariah's passing.
25:06She just seemed to float around like an angel.
25:09And everyone's just sort of reeling from it.
25:11It's just tragic.
25:12And it's sad for Austin and all of the Austin bike community.
25:17The moment we cease to hold each other, the moment we break faith with one another,
25:21the light goes out.
25:23I spoke with Mariah's family and expressed my condolences to them.
25:28And it was difficult for them to accept that their daughter had been killed.
25:35While police are investigating the murder of Mo Wilson,
25:38back in Vermont, her family is putting together a memorial,
25:42and they put out a statement about the race.
25:45Ahead of today's gravel low-coast race in Heiko, her family published a statement saying she was,
25:51quote, always pushing tirelessly to reach her goals.
25:54The family adding, we know Mariah would want the event to carry on.
26:00Around this time, detectives returned to the neighborhood where the murder occurred
26:04to see if they can find any additional video to confirm that Colin did actually drop Mariah off on his
26:10motorcycle and leave.
26:11At one of the houses in particular, they had actually opened the door to the carport at 836,
26:17which activated the motion sensor camera.
26:20At that same time, Colin's motorcycle can be seen driving in the alleyway leaving from Cash's residence.
26:28And we saw the black Jeep a minute later.
26:30This confirmed that Colin was, in fact, telling the truth about being on his motorcycle,
26:36and he was not driving Caitlin's black Jeep.
26:40Not long afterwards, police get a two-hour long tape,
26:45and it turns out to be one of the most frightening pieces of evidence in the entire case.
26:50It was a continuously recording doorbell camera that was across the street from where this murder occurred.
26:56I was typing my report, and I had this video playing in the background.
27:00Any time that I heard a vehicle passing by, I would review the camera, see if it is the vehicle
27:05that was in question,
27:06and the video continued to play.
27:14On the video, at approximately 9.15 p.m., I heard a female screaming.
27:26There were two gunshots, a six-second pause, and a third and final gunshot.
27:33I now had the exact moment of when this murder occurred.
27:39I listened to it, and it was heartbreaking.
27:41In that moment, I kind of felt like I was standing in her shoes.
27:51The following day, Colin Strickland and Caitlin Armstrong's cell phone data comes in.
27:56Colin's phone was pinging away from the scene when we knew the murder occurred,
28:01so we started to focus on Caitlin's phone records.
28:04Those records indicated that she had left her residence around 7 p.m., traveled into downtown Austin,
28:11and then was driving around through the area before beginning to head into East Austin where this murder occurred.
28:19At about 7.30 p.m., her device is no longer communicating with the network towers.
28:26Caitlin's phone did not reconnect to a tower until 9.55 p.m., showing to be at her residence.
28:32It appears that Caitlin's phone was turned off during the time the murder took place,
28:37and although this is suspicious, there still isn't enough evidence to arrest her.
28:41But that all changes six days after Mo's murder.
28:45On May 17th, we actually received a ballistics report back,
28:49saying that the ballistics did match the bullet fragments from the scene.
28:55The handgun that it matched was Caitlin's sixth hour.
29:00From the phone data, we knew that Colin was at home using his phone at the time of the murder.
29:06And Caitlin's black jeep was seen on surveillance footage outside of Cash's apartment.
29:12And only these two people had access to the firearm that was used to commit the murder.
29:18So we believe that we had enough probable cause to issue an arrest warrant for Caitlin Armstrong.
29:25Once the arrest warrant for Caitlin Armstrong was issued, we went to arrest her.
29:31But we realized that Caitlin Armstrong was nowhere to be found.
29:36U.S. Marshals are searching for this woman, Caitlin Marie Armstrong, charged with the murder of Anna Maria Wilson.
29:42She knew she was going to be wanted for this.
29:44She probably had a five-day head start.
29:55Caitlin cannot be found. She has gone off the grid.
29:58So we asked Colin about Caitlin.
30:01Colin had hired an attorney until this case was resolved.
30:04And the attorney had recommended that until everything was settled to no longer speak with Caitlin.
30:10So Colin had not even been in contact with Caitlin and her whereabouts were completely unknown.
30:17After searching the city, we soon realized that she wasn't anywhere in the Austin area.
30:22Detectives reached out to the Austin airport to see if there's any surveillance footage of Caitlin getting on a flight.
30:29We actually discovered video of Caitlin at the Austin airport.
30:32And she had on a blue jean jacket, a yoga mat.
30:37They confirmed through the flight manifesto that Caitlin Armstrong took a flight from Austin to Houston.
30:44And from there, she boarded a plane to Newark, New Jersey.
30:48Police wonder if she's there to catch a connecting flight out of the country.
30:52So we're looking at Caitlin's passport to see if anything comes back as having taken a flight out of the
30:58country.
30:59And nothing comes back.
31:01We started kind of thinking, did she go to family?
31:04Like, why the New York area?
31:06And we learned that she had a sister named Christine Armstrong that lived up in the New York area.
31:12Her sister looks a lot like her.
31:16And they're very close.
31:18And so we started to see if she's used her passport.
31:21The U.S. Marshals confirmed that Christine's passport had been used to fly from New York to Costa Rica.
31:29And they confirmed Christine was still currently in New York.
31:34So this is raising red flags that now Caitlin has left the country and she's now in Costa Rica.
31:41While the U.S. Marshals head down to Costa Rica to try to locate Caitlin, in Vermont, Mariah's family holds
31:47a memorial at her old school.
31:49Mariah, our beloved daughter, we're gathered here today to celebrate your life.
31:53You show us all how to love and live a meaningful life.
31:59I hope and pray that we can all take a small piece of your spirit and wisdom to help us
32:05lead more passionate, fulfilling and loving lives.
32:08You will be forever in our hearts.
32:11Love, Dad.
32:15As the U.S. Marshals are trying to track down Caitlin Armstrong, a woman who is friends with Caitlin Armstrong
32:21contacts the Austin police.
32:25Give me all the information that you can and how you got the information.
32:28Okay.
32:29So there was a conversation that I had with Caitlin Armstrong back in January regarding Mariah Wilson.
32:37Okay.
32:38Colin has been seeing Mariah Wilson on the side.
32:43Caitlin found out about it and she's very upset.
32:47Mariah was in the same vicinity at the same party and Caitlin was very shaken up.
32:52She was shaking, trembling and she was like, I wanted to kill her.
32:57You know, I didn't think anything happened.
32:58She's like, no, no.
32:59I mean, like, I really wanted to kill her.
33:03Based on that information, we knew that this had been going on for several months.
33:09The jealousy had started months before.
33:13Around this time, the lab results come back from the swab taken from Mariah's bike.
33:18And there is female DNA present that does not belong to Mariah.
33:22We're thinking hopefully that's Caitlin's DNA on the bike.
33:27And so they have to get a DNA swab of Caitlin Armstrong's to see if that will match.
33:33But the only problem is, is where's Caitlin Armstrong? She's in the wind.
33:38U.S. Marshals figured that after more than a month on the run, she must be working in some capacity
33:43to survive.
33:43Since Costa Rica is a popular spot for yoga retreats and she's a licensed yoga instructor, the marshals wonder if
33:50she might be looking for employment as a yoga instructor.
33:53We had intelligence indicating that she was staying in hostels in Costa Rica.
33:59They had local Costa Rican authorities start looking around at yoga studios where she could be staying, living or even
34:06possibly teaching.
34:07We decided we were going to put an ad out for a yoga instructor.
34:11The marshals put an ad out on the local Costa Rican websites looking for a private yoga instructor from the
34:17U.S.
34:17And shockingly, Caitlin responds with the address of the hostel where she's living.
34:25So one of the U.S. Marshals actually went in to look for her.
34:30And she had actually changed her appearance.
34:33She dyed her hair and it's obvious she's had some kind of work.
34:38But they know this is her.
34:40The marshals place Caitlin Armstrong into custody and prepare to bring her back to the U.S.
34:45I was extremely happy.
34:47I could not wait to tell Mariah's family that the person who killed their daughter was finally found.
34:53Seven weeks after Mo Wilson is murdered, Caitlin Armstrong is deported back to the U.S.
35:00And she ends up in Houston.
35:04We drive down there. We go try and interview her at the Houston homicide office.
35:08And immediately when I walk in, very, very cold, heartless, blank stare.
35:14And she immediately lawyered up this time.
35:17So we weren't able to ask her any questions.
35:19But I collect her DNA and then we turn it over so it can be analyzed and compared to the
35:25other DNA that we have from Mariah's bike.
35:27We compared her DNA and it proved to match DNA found on the handlebar and the seat of the bike.
35:36The DNA coming back on the bike was huge.
35:39There is no reason that Caitlin's DNA should be on Mariah's bike.
35:42There's no explanation for that.
35:44This was kind of the nail in the coffin.
35:48For more than a year, the Travis County D.A. prepares to try the first-degree murder case.
35:53And then, just as the trial is about to begin in October of 2023, Caitlin Armstrong injures herself while in
36:01prison.
36:02Caitlin had told the staff that she had a leg injury and she didn't believe that the doctors at the
36:08jail were competent enough.
36:10She wanted an outside doctor to be able to give their opinion.
36:14Her request was granted and she was sent to an outside doctor.
36:20Then we're all sitting around the table in the homicide office and someone comes out and yells that Caitlin just
36:26escaped from Travis County Jail.
36:36While at that doctor's office, Caitlin fled the scene. She broke away from the deputies and ran.
36:43There's video footage of her running down the street wearing her prison garb with handcuffs on her wrist.
36:51It's very interesting to see her in the black and white striped jail outfit running away trying to jump over
36:58a fence.
36:58I remember thinking, like, innocent people don't run away.
37:02Watching that video was rough because I think all of us are just in this mindset of, like, please, God,
37:09do not let her escape again.
37:11That would just be heartbreaking for the family.
37:15She ran for approximately one mile before she was found and taken back into police custody.
37:22Two weeks after her failed attempt to escape, her trial begins.
37:27Caitlin is being charged with first-degree murder.
37:31The last thing Mo did on Pittsburgh was scream in terror.
37:37Followed by.
37:41Two guy shots.
37:44Caitlin Armstrong stood up with Mo Wilson.
37:47Put a third shot right in Mo Wilson's heart.
37:52Although the prosecution presents evidence that the murder weapon belonged to Caitlin Armstrong,
37:57that her DNA was on Mariah's bike and her Jeep was at the crime scene,
38:01the defense pointed to the fact that they could not see who was driving that Jeep Cherokee.
38:08Not one witness saw Caitlin Armstrong allegedly commit this murder. Not one.
38:17After two weeks of trial, the jury came back with a verdict.
38:22Breaking news tonight.
38:23A jury finds Caitlin Armstrong guilty of murdering Anna Mariah Mo Wilson back in May 2022.
38:28Jurors deliberated for only two hours before returning with the verdict.
38:33There really are no winners here.
38:35This is not a time for celebration, but a time for prayer.
38:40Both Caitlin Cash and Mariah's mother, Karen Wilson,
38:43give emotional victim impact statements at the sentencing.
38:47I fought for Mo with everything I had that night.
38:51It never actually crossed my mind in the chaos of that night that she would die,
38:55that she was already dead when I arrived home.
38:59The ripple effect is almost incomprehensible.
39:02So many people in this room have lost so much.
39:09I hate what you did to my beautiful daughter.
39:12It was very selfish and cowardly because you never chose to face her woman to woman.
39:19She would have cared about your feelings.
39:23If you allowed yourself to actually know her, you never, ever would have wanted to hurt her.
39:31The jury gave Caitlin a 90-year sentence.
39:38I think what struck me about the story in particular was Caitlin's rage and where it took her.
39:46I found that deeply shocking and disturbing.
39:50The idea that she stood over Mariah in that sort of formal execution style
39:56and just shot her in the heart was just chilling to me, chilling.
40:04Mariah was young. She was only 25 years old.
40:06She had this massive, promising career.
40:09Her life was taken from her.
40:11And whatever made Caitlin do this, it was very trivial.
40:16I have worked a lot of different murders and they're all terrible.
40:21But this one really stands out.
40:23To be gunned down because somebody's upset that their boyfriend's talking to her.
40:29I mean, it's just so senseless.
40:33After their trial, the Wilson family starts a foundation called the Mariah Wilson Foundation
40:38in Mariah's memory.
40:39They raise money to expand access to sports education and recreation
40:44and they host a race every year around Mariah's birthday in May called Ride for Mo.
40:50Welcome to the first annual Ride for Mo.
40:54Thank you for coming to spend this beautiful day with us where Mariah grew up
40:59and where the love of biking was nurtured.
41:01Mariah was a wonderful daughter, sister and friend of many of you.
41:06Mariah lived her life in a very intentional manner.
41:09She knew what she wanted.
41:10She pursued her dreams.
41:11And I know she was an inspiration to all of us.
41:15She would want us to feel joyous today.
41:17So let's be together and let's ride some bikes.
41:37We'll come and die this.
