Never-before-seen evidence in the Kaitlin Armstrong murder case, the Texas yoga instructor convicted of killing a woman with whom her boyfriend had a fling, will be shown tonight for the first time.
Armstrong, 35, was found guilty last year of murdering professional cyclist Moriah Wilson by an Austin jury. She was sentenced to 90 years in prison.
For the first time, the Costa Rican plastic surgeon who operated on Armstrong when she fled Austin after she became the prime suspect in Wilson's death will be interviewed on Dateline NBC tonight.
Armstrong had a nose job and brow lift while on the lam. She flew to New York City and then Costa Rica using her sister Christie's passport just days before the Austin Police Department issued an arrest warrant for her.
When she landed in Central America, Armstrong contacted a doctor about changing her appearance, using the name Allison Paige.

The Costa Rican doctor recalled that Armstrong showed up to her surgery with her entire face covered up except for her eyes, the surgeon told Dateline NBC
The night Moriah Wilson was killed in May 2022, she met up with Armstrong's boyfriend for burgers and drinks in Austin, Texas
Moriah Wilson (left) who went by 'Mo', was an up-and-coming cyclist, and was described as a prodigy. She met Colin Strickland, who was a celebrated cyclist in his own right. Although Strickland dated and lived with Kaitlin Armstrong, Wilson and Strickland had a sexual relationship in fall of 2021 when Armstrong and Strickland were broken up
The surgeon described her as a normal patient, except for how she showed up looking on surgery day.
'She had like a hat, a hoodie, and also, she had a mask over her face,' the doctor recalled, adding that only her eyes were visible.
The medical professional claimed to be unaware she was wanted by authorities.
New video of Armstrong being questioned by Austin police and of first responders rushing to save Wilson after she was shot will also be featured in the network special, airing Friday.
Wilson, a rising star in the gravel cycling, had had a sexual relationship with Armstrong's boyfriend, Colin Strickland, when the couple briefly broke up.
Strickland maintained contact with Wilson even after he and Armstrong got back together.
He changed Wilson's contact name in his phone so that Armstrong would not know they were still in touch, according to court testimony.

In May 2022, Wilson traveled to the Texas capital for a race and made plans to meet up with Strickland for dinner.
Armstrong followed them to the restaurant, her Black Jeep caught on surveillance video circling the block as Wilson and Strickland were unaware they had been followed.
After the meal, Strickland gave Wilson a ride to her friend's apartment, where she was staying, and left.
Surveillance video showed Armstrong arriving at the friend's home where Wilson was staying and firing three gun shots, followed by Wilson's screams.
Viewers will also hear from the two US Marshals who were dispatched to Costa Rica to look for Armstrong while she was on the run.
Most of the evidence in the TV special were shown during Armstrong's November murder trial in the Lone Star State, however, cameras were not allowed by the judge except for closing and opening statements.
Most of the images in the show have never been seen by the public.
