Kaitlin Armstrong has been sentenced to 90 years in prison for the murder of professional cyclist Anna Moriah "Mo" Wilson. Armstrong was found guilty of fatally shooting Wilson, 25, in Austin, Texas, in May 2022, in what police said at the time appeared to be a targeted homicide. Prosecutors presented video, cellphone, ballistic, and DNA evidence they said proves Armstrong killed Wilson in the trial.

Kaitlin Armstrong's motive for the murder of Mo Wilson was believed to be romantic jealousy ignited by Wilson's casual encounter with Armstrong's boyfriend, pro cyclist Colin Strickland. Armstrong had access to her boyfriend's emails and text messages with Wilson. Using this, she was able to track Wilson's location through a fitness app . 

A day after being interviewed by police about Wilson's murder, prosecutors say Armstrong sold her Jeep and later fled to Costa Rica. She was arrested in June 2022 at a hostel on Santa Teresa Beach. The sentencing came a day after a jury found her guilty of first-degree murder after deliberating for fewer than three hours .

The jury deliberated for several hours on Friday before reaching the sentencing decision, which also included a $10,000 fine.
