Murder investigation

As per CBS, Wilson was fatally shot at her friend's home in Austin on the night of May 11, 2022. Having spent much of the day with her, Colin Strickland was the last person to witness her alive. Police first regarded Strickland as a suspect, but the inquiry soon turned toward Kaitlin Armstrong. Armstrong had a history with Strickland and was said to be envious of Wilson's connection with him.

Armstrong's home and crime scene evidence linked her to the shooting. Armstrong was arrested on an unrelated warrant shortly after the murder but was let go because of a clerical mistake. She vanished two days later and became the target of a national and international manhunt.

As per CBS, the search for Armstrong took 43 days and included several law enforcement organizations, including the Lone Star Fugitive Task Force and U.S. Marshals. Found at last in Costa Rica, where she had been living under a bogus name and had changed her appearance, she was apprehended. Armstrong's arrest brought her back to Texas to face trial after a tense period of uncertainty.

Trial, conviction, and consequences

As per ABC News, in November 2023, Kaitlin Armstrong's trial ended with a conviction for the murder of Anna Moriah Wilson. After only a few hours of consideration, the jury gave Armstrong a 90-year jail sentence. Prosecutors claimed that Armstrong's actions were fueled by envy over Wilson's brief romantic relationship with Strickland and her continuous friendship with him.

Armstrong's defense aimed at a reduced punishment, but the jury's judgment mirrored the gravity of the crime. Wilson's family expressed a desire to heal and recognized the permanent effects of the catastrophe following the verdict. Before the trial, Armstrong tried but failed to get out of custody.

Seeking damages and to stop Armstrong from profiting from the crime, Wilson's parents also brought a civil wrongful death lawsuit. Additionally, the case greatly affected the cycling scene, which had also been the focus of media adaptations.
