The world of professional gravel cycling is an incredibly intimate ecosystem. It is a grueling, dirt-swept arena where elite athletes spend grueling hours riding side by side, sharing dinner tables before massive endurance races, and forging deeply bonded friendships. In this fiercely competitive but closely knit community, anonymity is virtually nonexistent. By the spring of 2022, one name was echoing louder across the landscape than any other: Anna Moriah Wilson. Known affectionately to everyone as “Mo,” she was rapidly ascending to the very pinnacle of the off-road racing scene. Yet, as she was busy chasing her professional dreams and shattering course records, a terrifying and meticulously calculated obsession was silently building in the background. Someone was watching her every move, tracking her digital footprint, and preparing to commit an unspeakable act of violence that would permanently scar the sport and destroy a beautiful, promising life.
Anna Moriah Wilson was not initially destined for a bicycle. Raised in the snowy, mountainous terrain of the Northeast Kingdom of Vermont, her childhood was entirely consumed by alpine skiing. Coming from a deeply athletic family of elite skiers—her aunt was a two-time Olympian—Mo possessed an intense, natural competitive drive from a very young age. However, after suffering multiple devastating ACL tears during her high school and collegiate years at Dartmouth College, her Olympic skiing dreams were brutally derailed. Instead of surrendering to the crushing disappointment, Mo channeled her immense athletic spirit into cycling. Her rise was nothing short of meteoric. Within a span of just three years, she transformed from a passionate amateur into the undisputed “winningest woman” in the American off-road scene. She was securing massive corporate sponsorships, quitting her comfortable office job to race full-time, and radiating an infectious, humble joy that made her universally beloved by peers and competitors alike.
However, her extraordinary upward trajectory intersected fatally with the chaotic personal life of Colin Strickland, a highly successful and stubbornly independent professional gravel cyclist based in Austin, Texas. Strickland had spent years navigating a turbulent on-again, off-again relationship with Kaitlin Marie Armstrong, a real estate agent and yoga instructor who had seamlessly embedded herself into his life and managed his lucrative finances. During a brief period when Strickland and Armstrong were separated in late 2021, Strickland and Mo shared a short romantic fling. While the romance quickly cooled into what Strickland described as a strictly platonic and professional friendship, the emotional fallout was a ticking time bomb waiting to detonate.
When Armstrong and Strickland inevitably reconciled and resumed living together, Strickland made a catastrophic decision: he decided to completely hide his ongoing friendship with Mo. He changed Mo’s name in his phone to disguise her identity, routinely deleted their text exchanges, and attempted to completely compartmentalize his life to avoid Armstrong’s fierce wrath. But Kaitlin Armstrong was not in the dark. She had unfettered access to Strickland’s devices, emails, and social media accounts. More terrifyingly, she began utilizing Strava, a popular GPS-based fitness app, to actively monitor Mo’s training routes and daily locations. Armstrong’s jealousy festered into a lethal, burning obsession, culminating in chilling remarks to friends where she explicitly stated her desire to kill the young cycling phenomenon.
The tragic climax of this terrifying digital stalking occurred on May 11, 2022. Mo had traveled to Austin to compete in the Gravel Locos race, staying at the home of her close friend, Caitlin Cash. That evening, Mo innocently went swimming at a public pool and grabbed dinner with Strickland. They returned to Cash’s apartment shortly after 8:30 p.m., and Strickland promptly drove away on his motorcycle. He had absolutely no idea that Armstrong had been meticulously tracking his location the entire night. Within sixty seconds of his departure, surveillance cameras captured Armstrong’s black Jeep Grand Cherokee pulling into the alleyway behind the residence. Armstrong entered the apartment and confronted Mo in the bathroom. The resulting violence was merciless, deeply personal, and highly calculated. Armstrong shot Mo three times—twice in the head, and once directly in the heart as she lay defenseless on the floor.
When investigators connected the dots using neighborhood surveillance footage and ballistic matches from a firearm purchased by Strickland, they brought Armstrong in for questioning on an outstanding, unrelated misdemeanor warrant. What should have been the triumphant end of the manhunt instead became a shocking display of administrative failure. A clerical error regarding Armstrong’s date of birth rendered the warrant invalid, and she calmly walked right out the front doors of the Austin Police Department as a free woman.
Knowing the authorities were rapidly closing in, Armstrong executed a sophisticated and desperate escape plan. She sold her Jeep to a dealership for quick cash, stole her sister’s passport, and boarded a flight to San Jose, Costa Rica. Once in Central America, she completely immersed herself in the shadows of the surf and yoga community of Santa Teresa. To evade international law enforcement, she cut and dyed her hair brown, cycled through various aliases, and even underwent black-market plastic surgery—including a rhinoplasty and lip fillers—to permanently alter her facial features. She was determined to erase Kaitlin Armstrong entirely.
But the U.S. Marshals are not easily deterred. After weeks of exhausting dead ends and false sightings in the dense coastal towns, elite investigators deployed a brilliant psychological trap. Knowing Armstrong’s deep affinity for yoga instruction, they posted a fake job advertisement for a yoga teacher in a local Facebook community group. The desperate fugitive took the bait. When an undercover agent met her at a local hostel to discuss the fake position, he recognized her eyes despite the heavy surgical bandages across her swollen nose. Forty-three days after the brutal execution of Mo Wilson, Kaitlin Armstrong was finally placed in handcuffs and deported back to Texas to face justice.
Even behind bars, Armstrong’s sheer audacity never wavered. Just weeks before her highly anticipated murder trial in October 2023, she orchestrated a desperate and highly dangerous escape attempt. During a medical transport outside the jail, she managed to pop open her handcuffs with a hidden piece of metal, stripped off her striped prison uniform to reveal hidden thermal leggings, and sprinted into a South Austin neighborhood. She scaled a six-foot fence and ran for nearly a mile before exhausted officers finally tackled her to the dirt.
When the trial finally commenced in November, the prosecution presented a devastatingly thorough case. They showcased the damning GPS data mapping her Jeep’s exact movements outside the crime scene, the irrefutable ballistics evidence linking her directly to the murder weapon, and the chilling internet searches she conducted while on the run, including inquiries on whether pineapples could burn off human fingerprints. After just a few short hours of deliberation, the jury delivered a resounding guilty verdict. During the intensely emotional sentencing phase, Mo’s devastated family and friends confronted the remorseless killer, speaking to the immeasurable pain she had caused. The jury ultimately handed down a staggering ninety-year prison sentence, ensuring that Armstrong will spend the vast majority of her natural life locked away from society.
The tragic loss of Anna Moriah Wilson has left an unfillable void in the world of professional cycling and in the hearts of everyone who had the privilege of knowing her. She was a radiant, compassionate force of nature who wanted nothing more than to inspire young girls to ride bikes, be active, and embrace the pure joy of athletics. In the wake of unimaginable grief, her family has channeled their devastating pain into a beautiful legacy, establishing the Moriah Wilson Foundation to help underprivileged youth access sports. While the legal proceedings have concluded and the killer is firmly behind bars, the vibrant spirit of Mo Wilson continues to echo through the mountains of Vermont and the gravel trails she loved so fiercely, serving as a permanent reminder of a brilliant life stolen far too soon.
