TX v. Kaitlin Armstrong: Love Triangle Murder Trial

Court TV cameras were permitted in the courtroom for opening statements, closing arguments, and the verdict.

AUSTIN, Texas (Court TV) — Kaitlin Armstrong has been found guilty of murdering elite cyclist Anna Moriah “Mo” Wilson. The penalty phase began immediately, and the same jury sentenced her to 90 years in prison.

Armstrong, 35, was apparently in the throes of a jealous rage on May 11, 2022 when she fired bullets into Wilson’s head and heart. Armstrong was allegedly furious that her boyfriend, professional cyclist Colin Strickland, had secretly gone out on a date with Wilson, 25.

A 43-day manhunt for Armstrong ensued when she skipped town after being questioned — and released — by police about why her 2012 Jeep Grand Cherokee was caught on surveillance video near the scene of the murder. Police didn’t have enough evidence to make an arrest, but Armstrong proceeded to sell her vehicle and hop on a plane. She went from Austin to Houston to New York and eventually landed in Costa Rica.

Armstrong was captured in Costa Rica in July 2022. She had apparently undergone plastic surgery and dyed her hair. She was lying low at a hostel and had been using her sister’s passport. Armstrong was extradited to the U.S., where she pleaded not guilty to the murder charge. Bail was set at $3.5 million and she has remained in custody ever since.

In addition to the murder charge, Armstrong faces a felony charge of escape causing bodily injury after she tried to escape from guards while at a doctor’s appointment in Austin on October 11. According to an affidavit, she took off while exiting the doctor’s office and made it about a mile on foot before being apprehended. Police believe the escape attempt was premeditated. They say Armstrong spent months “exercising vigorously,” she complained of an injury that required visiting a doctor outside prison walls, and the medical request ensured she would not be wearing leg restraints at her appointment.

On the Monday before her trial began, Judge Kennedy ruled that evidence in Armstrong’s alleged attempted escape would be allowed during her murder trial.

At the time of her death, Wilson was in Austin to compete in the 150-mile “Gravel Locos” bicycle race. Wilson, whose career was just taking off, had just reached top levels in both gravel and mountain biking in the U.S.

Investigators believe Wilson had unknowingly gotten caught up in a love triangle. She had dated Strickland during a brief period of time when he and Armstrong were on a break. Armstrong and Strickland reconciled soon after, but according to an arrest affidavit, Armstrong became furious when she found out about the romance.

Armstrong faced up to life in prison at sentencing. The jury sentenced her to 90 years in prison as well as a $10,000 fine.

Colin says Mo’s number was stored in his phone under the alias “Christine Wall.”
Colin answers questions about text exchanges he had with the defendant, Kaitlin Armstrong — according to him, Kaitlin was no longer his girlfriend at this point, she was a business partner. Kaitlin, however, was sending him texts asking him why he was calling Mo. (Kaitlin could access Colin’s Apple devices iCloud account and apparently could see a log of who he was calling and texting).
Colin also answered questions about handguns and ammunition he had purchased for he and Kaitlin, including an Sig Sauer 9mm.
The jury saw video of Kaitlin shooting her gun at a firing range.

Colin says that he and Kaitlin got back together after the fling with Mo, but at the time of Mo’s murder, he and Kaitlin were no longer a couple even though they were living in the same house. Says that he didn’t tell Kaitlin he was meeting Mo the night of the murder because he knew it would lead to a dramatic conflict. He admits he lied to Kaitlin about where he was that night.
Colin says Kaitlin was NOT a particularly jealous or needy girlfriend.
Colin says he knows Kaitlin called Mo in 2021.
Confirms that his relationship with Kaitlin lasted from Oct. 2019-May 2022 (except for the break during which he had the fling with Mo). Says that during that time, he never had sex with anyone else (Except with Mo, during the late 2021 fling during the breakup).

Mo was a college athlete and got into the sport of gravel racing.

We are here because of the State’s opinion of the case.

Geoffrey Puryear – CROSS

I believed Mo and Colin were colleagues and friends and knew they had been romantically involved but wouldn’t have categorized them as having dated or ever officially been boyfriend and girlfriend.

NOTE: Mo’s family left the courtroom after her brother testified so that they wouldn’t have to listen to details about her death, the 911 call, etc.,

State’s Witness #2 Caitlin Cash, Moriah ‘Mo’ Wilson’s Friend

DIRECT

At 5:05 p.m. the night of the murder, Mo texted Caitlin Cash to tell her she was going swimming with Colin.
At 5:55 p.m., Mo left Caitlin Cash’s house and locked the door. (Caitlin Cash’s apartment had a computerized lock where guests had individual codes, so times are accurate).
At 8:36 p.m., Mo unlocked Caitlin Cash’s apartment door.
At 9:54 pm, Caitlin Cash called 911.
When Caitlin got home, the door was unlocked, and she saw Mo’s feet sticking out from the bathroom. At first, she thought Mo was lying on the tiles because it was hot.
When Mo didn’t respond, Caitlin Cash walked closer and saw her lying there, covered in blood. She bent down and tried to wake Mo, then called 911.
Audio of the 911 call is played for the jury:
“I need EMS….(Background noise of Caitlin making noises)…1078 Maple Avenue behind the purple house…my friend is staying with me, and she’s laying on the bathroom floor and there’s blood everywhere and I don’t know what happened…my name is Caitlin….she has blood all over her face, and hair….Is she breathing? No. I’m by myself….lay her flat on her back on the floor…Is she lying flat on her back? Yes. Okay, I’m going to instruct you on how to do chest compressions….1, 2, 3, 4, 5, 6……….her brain is leaking….I understand, Caitlin, keep going…..I’m staring over….1, 2, 3, 4, 5……..I think she’s throwing up…Turn her to the side….Yes, it’s in her mouth….Once you have her mouth cleaned out, turn her back over and continue the chest compressions……ok 1, 2, 3, 4, 5,…….(continues to count)…..I hear them….that’s good, don’t leave her alone, just keep going….(continues to count)…..is the door unlocked…”
Caitlin Cash says she knew Colin and Mo had been romantically involved.
