Murder Trial Begins for Woman Accused of Killing Pro Cyclist Mo Wilson and Fleeing the Country

Armstrong, 35, engaged in significant efforts to evade authorities including fleeing to Costa Rica, undergoing surgery to alter her appearance, and a recent attempted escape from custody; the high-profile case, involving suspected use of a fitness app to track victim Wilson's movements, unreleased video of the victim's final moments, and a complex love triangle, is expected to last two weeks.

The murder trial for Kaitlin Armstrong began on November 1, 2023; she is accused of marking professional cyclist Anna Moriah “Mo” Wilson in May 2022 and fleeing the country. If convicted, Armstrong faces up to 99 years in prison.
The prosecution alleges that Armstrong tracked Wilson’s movements using a fitness app, and then shot Wilson three times, including one shot through the heart. The casings from the gunshot are suspected to match Armstrong’s handgun, and her vehicle matches one seen on security footage.
The prosecution will present surveillance footage audio at trial that captures Wilson's final screams and the gunshots that killed her. Armstrong’s defense attorney insists the case lacks video evidence or witnesses that can place Armstrong at the exact scene of the shooting.
After the murder, Armstrong managed to evade authorities for over 40 days by using her sister's details to travel to Costa Rica, where she paid approximately $6,500 for cosmetic surgery to alter her appearance, and made attempts to establish herself as a yoga instructor under a different alias.
On the day of the murder, Wilson had spent time with Colin Strickland, a pro-cyclist who Armstrong had been in an on-again-off-again relationship with, and who had been romantically involved with Wilson. She is suspected to have tracked Wilson's location through Strickland's communication with Wilson before the shooting.
