Colin Strickland is questioned by police

On May 12, 2022, the morning after Wilson's murder, police arrived at Strickland's home. They informed him that Wilson died, and the case was a homicide investigation. They also saw a black Jeep SUV in Colin's driveway that matched the one seen on security footage the night before. Investigators had run the license plate and discovered it was registered to a woman named Kaitlin Armstrong.

Colin Strickland opens up about his and Wilson's past

After Wilson's death, Strickland took to social media and wrote that about six months before her murder, during a short break up with Armstrong, he did have a "brief romantic relationship" with Wilson that "spanned a week or so." He said that it ended, and their relationship had turned into a "platonic and professional one."

Strickland was ruled out as a suspect, and it was later discovered that he was on the phone when Wilson was murdered.

Kaitlin Armstrong brought in for questioning

On May 12, 2022, police arrested Armstrong on an old outstanding warrant for failing to pay for a Botox treatment and used the opportunity to inquire about Wilson's death. Investigators say she remained stoic during the questioning. When told her vehicle was seen near Cash's apartment, she said "I would like to leave." She responded in a similar fashion to other questions.

But Armstrong was released because the birthdate on the arrest warrant was wrong.

Kaitlin Armstrong disappears

On May 14, 2022 Armstrong fled Austin.

The Lone Star Fugitive Task Force, which included officers from the Austin Police Department and U.S. Deputy Marshals, was tasked with finding her.

Armstrong is seen in security footage from Austin-Bergstrom International Airport. She first headed to her sister's place in upstate New York and then headed to Costa Rica. The U.S. Marshals discovered that Armstrong used her sister's passport. Christie Armstrong emphasized to authorities that she had not given her sister the passport. Christie Armstrong has never been charged with anything related to this case.

Deputy U.S. Marshals Emir Perez and Damien Fernandez followed Armstrong to San José, but there was no sign of her in the city. 

The search proved increasingly difficult, until the Marshals got a lead that would inform them about Armstrong's new appearance — she had cut her hair short, dyed it brown, and was even going by a different name. They also learned that she likely fled to a tiny, one-street town called Santa Teresa. More than a month had passed since Armstrong fled, and Perez and Fernandez were running out of options. They decided on one last tactic. They posted an ad looking for a yoga instructor on a local Facebook page.

After a few days, no one had responded to the inquiry, so Perez and Fernandez were ready to head home. But then, they got a bite.

Kaitlin Armstrong is caught

Someone who identified themselves as a yoga instructor replied to the Facebook inquiry and agreed to meet. At this point, the Deputy Marshals also had a good idea of what hostel Armstrong was staying at in Santa Teresa and had help from the local Tourism Police surveilling that hostel.

Perez noticed a bandage on Armstrong's nose, and that her lips were swollen, but he wasn't convinced until he got a close look at her eyes. He knew those eyes matched Armstrong's picture and was confident they had the right woman.

Perez told the rest of the team on the ground it was her and local police moved in to make the arrest.

Perez went inside the hostel alone and approached Armstrong at the front desk where she was working. He pretended to be a tourist, speaking Spanish, to not scare her off.

Kaitlin Armstrong's plastic surgery confirmed

A receipt for cosmetic surgery was found at the hostel where Armstrong was captured. The date on the receipt confirmed that when the Deputy Marshals were first in Santa Teresa looking for Armstrong, she was in San José getting surgery.

This, in addition to her new appearance, added to the difficulty in finding Armstrong when the Deputy Marshals first arrived in Santa Teresa. 

Kaitlin Armstrong extradited to the U.S.

The Deputy Marshals took Armstrong back to Texas where she was charged with Wilson's murder and held in jail. 

Kaitlin Armstrong escapes again

Three weeks before Armstrong's trial was set to begin, she was escorted by authorities to a doctor's appointment where she escaped custody and ran away. Armstrong was caught shortly after.

Guilty of first-degree murder

On Nov. 16, 2023, after a two-week trial, a jury found Armstrong guilty of first-degree murder. She was sentenced to 90 years behind bars the next day.

Moriah's Ascent

Wilson wanted to give back to the cycling community and find meaning in the sport that went beyond results.

To honor Moriah, the Wilson family created the Moriah Wilson Foundation that promotes healthy living and community building.

In Kingdom Trails in northern Vermont, a place that was sacred to Wilson, a trail was built in her honor called Moriah's Ascent.
