REVEALED: Killer yoga teacher Kaitlin Armstrong claims she was PREGNANT near the time of her arrest as she appeals for a new trial after being sentenced to 90 years in prison for gunning down love rival Mo Wilson

Texas killer Kaitlin Armstrong, who was recently found guilty of shooting her love rival, has bombed her claim that she was pregnant at the time of her arrest, new court documents reveal.

The shocking accusation was made in a court filing obtained by DailyMail.com, in which Armstrong's lawyer is asking for a new trial.

Wilson was sentenced last month to 90 years in prison for fatally shooting Mo Wilson, a professional cyclist who had dinner with Armstrong's friend the night of the killing.

Wilson and Armstrong's live-in boyfriend Colin Strickland dated briefly in 2021 when Armstrong and Strickland split, but later got back together.

The current attorney for the convicted murderer believes a jury might have sentenced her to less time if they had known of her delicate condition.

“Kaitlin has also been pregnant twice, once during or around the time of her arrest,” the filing reads.

Moriah Wilson (left), who went by 'Mo', was an up-and-coming cyclist and described as a child prodigy. She met Colin Strickland, who was a celebrated cyclist in his own right. Although Strickland was dating and living with Kaitlin Armstrong, Wilson and Strickland were in a sexual relationship in the fall of 2021 when Armstrong and Strickland broke up.

“Given that the sentence here was ninety years and a maximum fine, there should be no doubt that this mitigating evidence would have resulted in a milder sentence.”

Austin attorney Adam Loewy told DailyMail.com that it was “stunning news if true, bBut there are many problems with the theory.'

Armstrong was arrested after more than two months on the run in Costa Rica, where she fled after becoming the prime suspect in Wilson's murder in May 2022.

While on the run in Central America, Armstrong underwent plastic surgery to change her appearance, including a rhinoplasty and a brow lift.

She also had fillers injected into her face and her hair dyed from red to brown.

During her murder trial in November, testimony revealed that she had lab work done prior to her cosmetic procedures.

Plastic surgeons routinely check a patient's general health and whether she is pregnant prior to elective surgery, such as a rhinoplasty.

In fact, Armstrong's surgery was postponed for a day, a witness testified, because Armstrong failed to complete the labs.

Her doctor's office told her they were necessary.

She had the labs done the next day and was able to go under the knife.

In the new documents, her attorney portrays Armstrong as the daughter of an alcoholic mother whose father abandoned her and who was the victim of sexual abuse.

“While her family struggled throughout her childhood, her childhood friend also recalled Kaitlin being the victim of multiple instances of (actual or attempted) sexual assault,” her attorney claims.

Armstrong is expected to be released from prison in March 2112 and she is not eligible for visitation

None of these claims were made during Armstrong's trial in Austin, which lasted more than two weeks.

“The fact is she's just trying, or her new attorneys are trying, every kind of desperate attempt to overturn the conviction,” Loewy added.

'You try everything in these kinds of situations and you hope that the court will bite on something.'

The new image of Armstrong, a former yoga teacher, that her lawyers are trying to paint is a far cry from the evidence jurors heard in court.

They saw real photos of her shooting a gun at a shooting range, and they heard evidence that she stalked Wilson on an athletic app called Strava, which tracked her daily exertions.

Plus, Armstrong spent her time Googling herself and the murder investigation, and researching whether pineapple burns your fingerprints.

In October, she pretended to be injured when she went to a doctor's appointment days before her trial and tried unsuccessfully to escape police custody.

Against the advice of her trial attorney, Armstrong rejected a plea deal offered to her by the local district attorney before her trial began, as DailyMail.com exclusively reported.

“I just find it mind-boggling that she literally refused to consider a plea offer that would have gotten her out of prison at 50 and now she will almost certainly die in prison,” he said.
