Who Is Kaitlin Armstrong? All About Moriah Wilson’s Killer [Video]

Kaitlin Armstrong became infamous when she was trying to remain anonymous.

The yoga instructor underwent a major makeunder after she murdered bicyclist Anna Moriah “Mo” Wilson in 2022. The late athlete briefly dated Armstrong’s on-and-off-again boyfriend, fellow pro cyclist Colin Strickland, setting Armstrong into a jealous rage that led to Moriah’s shooting death.

Armstrong went on the run and under the knife in an attempt to evade investigators, even trying to escape from corrections officers on foot before her trial. The wild case was even fictionalized in a 2024 Lifetime movie, Yoga Teacher Killer: The Kaitlin Armstrong Story.

Still, those who knew Armstrong before Wilson’s murder claim that by most accounts she and Strickland had a relatively “normal” life and relationship. One exception? Her jealousy of Strickland’s friendship with Wilson.
