The Moriah Wilson Case — Cyclist Murdered by Rival in Austin

The Case

The Moriah Wilson case is a solved American homicide in which 25-year-old professional gravel cyclist Anna Moriah "Mo" Wilson was shot and killed in Austin, Texas, on May 11, 2022. Yoga teacher and real estate agent Kaitlin Marie Armstrong, then 35, was convicted of first-degree murder in November 2023 and sentenced to 90 years in prison. Prosecutors argued the killing was driven by romantic jealousy linked to Armstrong's on-and-off relationship with cyclist Colin Strickland, who had briefly been involved with Wilson.

The Crime

On the evening of May 11, 2022, Wilson was visiting a friend's residence in East Austin ahead of a major gravel race in Hico, Texas. Earlier that day she had gone swimming with Strickland, who then dropped her off at the home. Shortly after, Armstrong arrived in a black Jeep Grand Cherokee fitted with a bike rack. Wilson was found by her friend a short time later, fatally shot on the bathroom floor.

Ballistics analysis tied the bullets to a SIG Sauer P365 pistol that Armstrong owned. Surveillance video from the neighborhood captured the SUV near the residence at the time of the killing, and detectives quickly built a timeline matching Armstrong's movements to the crime scene.

The Victims

Anna Moriah "Mo" Wilson, known as Mo, was one of the fastest-rising stars in American gravel and mountain bike racing. At just 25, she had become a dominant figure on the off-road endurance circuit, winning major events across the United States. Friends, sponsors, and fellow racers described her as humble, fiercely talented, and devoted to the sport. Her death sent shockwaves through the international cycling community and prompted tributes at races worldwide.

Investigation

Austin Police Department detectives moved quickly. Within days they had identified Armstrong as a suspect through tips from people in the cycling scene who knew of the love triangle, security footage of the Jeep, and the ballistics match to her registered firearm. When officers brought Armstrong in for questioning, procedural issues led to her release — and she promptly disappeared.

Armstrong sold her vehicle, used a fraudulent passport, and flew to Costa Rica. The U.S. Marshals Service launched an international manhunt, eventually tracking her to a hostel in Santa Teresa on June 29, 2022. She had altered her appearance, including cutting and dyeing her hair and undergoing minor cosmetic changes, but was identified and arrested after roughly 43 days on the run. She was extradited back to Texas to stand trial.

Trial and Verdict

The trial opened in Travis County in October 2023. Prosecutors presented a methodical case built on digital evidence, including Strava fitness app data showing Armstrong tracking Wilson's movements, surveillance footage of the Jeep Grand Cherokee, ballistics, and witness testimony from Strickland. Just days before closing arguments, Armstrong briefly escaped custody during a medical transport, leading to an additional charge of escape causing bodily injury, according to CBS News coverage of the trial.

On November 16, 2023, the jury found Armstrong guilty of first-degree murder. She was sentenced to 90 years in prison. In June 2024, a civil court ordered her to pay $15 million to the Wilson family in a wrongful-death judgment.

Today

Armstrong's conviction was upheld on appeal in January 2026, closing the principal legal chapter of the case. The murder has generated substantial media coverage, including features in Bicycling and CBS News, an A&E special, and multiple long-form YouTube documentaries. In April 2025, Netflix released The Truth and Tragedy of Moriah Wilson, profiled in Biography's reporting on the case, examining Wilson's career, the love triangle, and the international manhunt that followed.

Mo Wilson's family established a foundation in her name to support young female athletes, ensuring that her legacy in the cycling world extends beyond the circumstances of her death.
