US marshals caught a yoga-enthusiast-turned-fugitive in Costa Rica through a fake yoga instructor ad

On May 11, 2022, yoga instructor Kaitlin Armstrong fatally shot professional cyclist Anna Moriah Wilson in what authorities called an act of jealousy over Wilson’s prior relationship with Armstrong’s boyfriend

A video showing Armstrong’s Jeep at the murder scene tipped authorities off to her involvement, but before they could locate and arrest her, she fled abroad using her sister’s passport

Authorities tracked Armstrong to Costa Rica, where she had assumed a fake identity and undergone plastic surgery to change her appearance

They believed she was hiding in Santa Teresa, a beach town outside the country’s capital, but had difficulty finding her

“I think from the get-go we were told…you’re gonna be in for a surprise, ‘cause a lot of the women in Santa Teresa look just like Kaitlin – a lot of them,” a US marshal recently told CBS

The case went cold until US marshals devised a new method to lure her out: An ad for a fake yoga instructor position

The ad said, “Hey, we’re at this hostel, we’re looking for a yoga instructor as soon as possible. Please contact us at this number,” a marshal told CBS

The ploy worked: Armstrong applied for the role, leading to her arrest and extradition to the US

A jury convicted Armstrong of murder in November, and she was later sentenced to 90 years in prison

US marshals publicly revealed the details of her arrest on CBS “48 Hours” program on Saturday
