On the night of May 11, 2022, 25 year old professional gravel cyclist Anna Moriah "Mo" Wilson was shot and killed inside a friend's East Austin, Texas apartment by Kaitlin Armstrong, the girlfriend of a fellow cyclist Mo had briefly dated months earlier.
Mo Wilson grew up in Kirby, Vermont, the daughter of Karen and Eric Wilson. A former competitive alpine skier at Burke Mountain Academy and Dartmouth College, she pivoted to cycling after injuries and turned professional in 2019. By 2022 she was widely considered the winningest woman in American off road cycling, with recent victories at the Belgian Waffle Ride California and Shasta Gravel Hugger.
Kaitlin Marie Armstrong, 34, was a yoga instructor and licensed real estate agent living in Austin. She was in a long term, on and off relationship with 35 year old professional cyclist Colin Strickland. During a brief separation in the fall of 2021, Strickland had a short romantic involvement with Wilson when Mo visited Austin. Although the two had returned to a platonic friendship and Strickland had reconciled with Armstrong, prosecutors would later argue Armstrong remained deeply jealous and had been tracking Wilson on the fitness app Strava.
In May 2022, Wilson flew from her home in San Francisco to Austin to prepare for the Gravel Locos race in Hico, Texas. She was staying with her friend Caitlin Cash at Cash's apartment on Maple Avenue in East Austin.
On the evening of May 11, Wilson met Strickland for a swim at Deep Eddy Pool and dinner at Pool Burger. He dropped her back at the apartment around 8:30 p.m. A neighbor's Ring camera captured Armstrong's black Jeep Grand Cherokee pulling up shortly after. Cash returned home around 10 p.m. to find Wilson unresponsive and called 911. Wilson had been shot three times. Investigators recovered Wilson's racing bike discarded in nearby bushes, with Armstrong's DNA on the handlebars and seat.
By the time a formal murder warrant was issued on May 17, Armstrong had vanished. She sold her Jeep to a CarMax for cash, used her sister's passport to fly from Newark to Costa Rica, dyed her hair, and underwent rhinoplasty under the aliases "Beth" and "Ari." U.S. Marshals tracked her to the beach town of Santa Teresa using a Facebook ad seeking a yoga instructor. She was arrested at a hostel on June 29, 2022, 43 days after the murder.

On November 16, 2023, a Travis County jury found Armstrong guilty of first degree murder and she was sentenced to 90 years in prison. On January 23, 2026, the Texas Third Court of Appeals upheld both the conviction and the sentence. Wilson's family established the Moriah Wilson Foundation in 2023, which hosts an annual Ride for Mo event in East Burke, Vermont.
The murder took place at a private apartment on Maple Avenue in East Austin, just east of the University of Texas campus. The home belongs to a private resident who had no involvement in the crime.
Please be respectful of the surrounding neighborhood and do not attempt to identify or visit the property. Those wishing to honor Moriah Wilson's memory can do so by supporting the Moriah Wilson Foundation or attending the annual Ride for Mo on the Kingdom Trails in Vermont.
