Kaitlin Armstrong’s Plastic Surgeon Says Fugitive Murderer Didn't Want 'Before' Photos Shot Prior to Operation

Dr. Jorge Badilla speaks out on tonight's 'Dateline' about the strange day Kaitlin Armstrong came to his clinic in Costa Rica for surgery

• Pro-cyclist Anna Moriah “Mo” Wilson was fatally shot ahead of a race on May 11, 2022

• Kaitlin Armstrong, who has been convicted of her murder, killed Wilson, who had dated Armstrong’s on-again off-again boyfriend when they were not together, after tracking her on an exercise app to Austin, Texas

• The target of the murder investigation, Armstrong fled to Costa Rica, where U.S. Marshals arrested her that June after she had already undergone face-altering plastic surgery

When Dr. Jorge Badilla first met Kaitlin Armstrong, she “behaved totally normal,” he tells Dateline in an exclusive interview about his client who turned out to be a murderer.

But on the day of her scheduled plastic surgery, Armstrong arrived at his practice in San José, Costa Rica, in a hoodie, with a mask covering her face.

Armstrong was a long way from home — on the run since killing Anna Moriah “Mo” Wilson, a professional cyclist who she considered to be a love rival, in a home in Austin, Texas, May 11, 2022.

Weeks later, Armstrong was in the plastic surgeon’s office, spending some $6,000 in an effort to change her appearance to better evade authorities.

This week's two-hour episode “The Night Time Stopped” airs on Dateline Friday, April 5 at 9 p.m. ET on NBC, and streams the next day on Peacock. (An exclusive clip is below.)

Filmed on location in Austin, Texas, and in Costa Rica, the episode will feature interviews with detectives and U.S. Marshalls who investigated the case, as well as footage of police questioning a key witness and never-before-aired evidence from the courtroom, which was used to secure Armstrong’s murder conviction in November.

Armstrong escaped custody just weeks before trial, making a run for it during a doctor's appointment outside the jail, dashing a mile on foot in her black and white prison stripes before the officers corralled her as she attempted to scale a six-foot fence. She was later convicted by a jury after two hours of deliberations.

Armstrong was sentenced to 90 years behind bars, after a jury determined that the yoga instructor had tracked Wilson on Strava, a workout app, and, finding her alone at a friend’s home, shot her in the heart.

In Badilla’s office, Armstrong — who was slated to get lip fillers, rhinoplasty and a brow lift, became agitated when the doctor wanted to snap a “before” photograph of her face.

“I needed to take some pre-op pictures because I do that for all the patients — just to have a before and after,” Badilla tells Dateline. “She didn’t want me to do that.”

Badilla — who knew Armstrong as Allison Page, one of several aliases she used — did not understand why the woman was so reticent, and he pushed for the photograph.

“The day of the surgery: it’s a must,” he says, of pressing Armstrong for the photograph. “She told me, ‘Okay, doctor, you can take pictures, but only with my cell phone.’”

Armstrong was captured by U.S. Marshals that June. Emir Perez of the Marshals Service later recalled in court that at the time of her arrest, her lips were swollen and a bandage covered her nose.

“Initially it did not appear to be her,” Perez told the jury. “But as I got closer, I realized it was her.”
