Key Witnesses Testify in Kaitlin Armstrong Murder Trial Over Cyclist Mo Wilson’s Death

Kaitlin Armstrong enters the courtroom.

In a significant development in the murder trial of Kaitlin Armstrong, two witnesses have testified that Armstrong had expressed a willingness to kill pro cyclist Mo Wilson if she dated her boyfriend. This revelation emerged during the trial for the May 2022 shooting death of Wilson, for which Armstrong, 35, has pleaded not guilty.

Armstrong’s former friends, Nicole Mertz and Jacqueline Chasteen, both testified about their interactions with Armstrong. Mertz, part of the Austin cycling community and once close to Armstrong, recalled a conversation at an Austin restaurant where Armstrong became visibly upset upon seeing Wilson, who had previously dated Armstrong’s boyfriend, competitive cyclist Colin Strickland. Mertz claimed that Armstrong had said she would kill Wilson if Strickland started dating her. Upon learning of Wilson’s death, Mertz contacted the police, feeling it was necessary to share this information.

Chasteen met Armstrong in Arkansas and testified that Armstrong had expressed thoughts of killing Wilson due to ongoing tension following Wilson’s relationship with Strickland. Like Mertz, Chasteen also reached out to the police after Wilson’s murder, initially anonymously, and later agreed to testify in the trial.

Detective Richard Spitler of the Austin Police Department also testified, detailing efforts to secure over 25 search warrants for cellphone data and account information. He revealed that a “recently deleted” file from Armstrong’s phone contained a Google Maps address matching the location of Wilson’s murder. Prosecutors suggest that Armstrong had been monitoring Wilson’s movements through the Strava fitness app.

Armstrong, after the murder, fled to Costa Rica where she taught yoga and underwent plastic surgery to alter her appearance. She was eventually apprehended by U.S. Marshals at a hostel and extradited back to the U.S.

Adding to the trial’s drama, Armstrong allegedly attempted to escape custody three weeks before the trial commenced. She faces a potential sentence of up to 99 years in prison if convicted of the murder charges.
