On the night of May 11, 2022, professional cyclist Anna Moriah "Mo" Wilson was fatally shot by Kaitlin Marie Armstrong at a friend's home in Austin, Texas.

Armstrong, a yoga instructor and licensed realtor, committed the crime out of jealousy triggered by Wilson's romantic encounter with her on-and-off boyfriend, pro cyclist Colin Strickland.

[7] Police named Armstrong a person of interest after video surveillance showed her black Jeep Grand Cherokee arriving at the Austin residence moments before the killing.

[5][6] Armstrong made no statement to the police when confronted about the video evidence of her vehicle; however, investigators observed she "turned her head and rolled her eyes in an angry manner" when questioned about how Wilson was with Strickland.

[4] Armstrong reportedly became aware of the relationship and expressed a strong desire to kill Wilson, telling an anonymous tipster that she "had either recently purchased a firearm or was going to."

A spent shell casing from one weapon, a SIG Sauer P365 handgun belonging to Armstrong, yielded a "significant" match with one found in the crime scene.

They observed that her appearance had changed drastically; her hair had been dyed and cut short, her nose had been bandaged, and there was some discoloration around her eyes, which she reportedly said were caused by a surfboarding accident.

[12] Armstrong had lost her bid to suppress evidence of her custodial interrogation with the Austin Police Department, which she argued was illegally obtained because she was not apprised of her Miranda warning.

[13] A federal charge of Unlawful Flight to Avoid Prosecution against her was provisionally dismissed as well; legal experts said such a motion was "routine" since she had a constitutional right to a speedy trial.

[23] On June 15, 2024, Lifetime did a television movie called Yoga Teacher Killer: The Kaitlin Armstrong Story as part of its "Ripped from the Headlines" feature films.

The film stars Caity Lotz as Kaitlin Armstrong, Kyle Schmid as Colin Strickland, and Larissa Dias as Moriah Wilson.
