'Killer' yoga teacher Kaitlin Armstrong declined to testify in her own murder trial where she's accused of killing love rival, as jury hears closing arguments

Closing arguments are underway in the Texas murder trial of Kaitlin Armstrong, who is accused of killing her boyfriend's love interest. 

Jurors in the case will not hear from Armstrong herself as she declined to testify in her own defense Wednesday. 

Armstrong, 35, faces murder charges in the May 11, 2022 shooting of Moriah 'Mo' Wilson, 25, a pro-cyclist who had dated Armstrong's boyfriend when the two had broken up but later reconciled.

Prosecutors came out swinging during closing arguments Thursday, telling an Austin, Texas courtroom that Armstrong was not the 'shrinking violet' her lawyers had described.

'This is your shrinking violet,' said prosecutors, as they flashed a wall-sized photo of Armstrong shooting a firearm at a gun range.

Jurors immediately heard surveillance video from the night of the murder of Wilson screaming, followed by gunshots.

'The last thing that Mo Wilson did on this Earth on May 11, 2022 at 9:15 p.m. was scream in terror,' state prosecutor Rickey Jones passionately declared. 

In her final hours alive, Wilson met up with Colin Strickland, Armstrong's live in boyfriend. 

After Strickland dropped Wilson off at a friend's apartment, a black Jeep belonging to Armstrong was caught by multiple surveillance cameras in the neighborhood. Her car's GPS and phone GPS also put Armstrong at the scene of the crime. 

Wilson was shot twice in the head, once in the heart, and once in the finger, the medical examiner testified earlier this week, explaining that the bullet wound on her finger was a defensive wound, meaning Wilson likely tried to shield herself from getting shot.

'Then she (Armstrong) runs to Costa Rica, gets plastic surgery, teaching yoga on the beach, while the Wilsons are left trying to pick up the pieces," Jones said referring to the victim's grieving family who have been in court every day for the last three weeks, taking up the first three rows of the gallery.

Armstrong fled Austin, Texas, days after Wilson's slaying to Costa Rica to avoid being charged. 

She left the country using a passport that belong to her sister, Christine.

US Marshals eventually tracked down her down to a remote beach town where she was living under several aliases and had a nose job and a brow lift. 

The former yoga teacher tried to escape from police custody a second time 19 days before her trial began. 

'She's running from you and you and you. You are a jury of her peers and everyone gets their day in court,' Jones said while pointing to members of the jury.

'Kaitlin Armstrong enters the courtroom,' tweeted News Nation reporter Alex Caprariello. 

'She is wearing a black pantsuit and dark teal blouse. She does not make eye contact with anyone as she enters. She takes her seat at the defense table. Two rows behind her sits her parents and her sister, Christine.'

'Never seen so much evidence in my life against one person,' Jones stated.

Cameras haven't been allowed in the courtroom for the trial that began Oct. 30, except for opening and closing statements.

Defense Attorney Rick Cofer is speaking to jurors now, describing Strickland as the 'poster boy for Peter Pan syndrome, describing him as a liar and womanizer.

'Mo Wilson was not the first woman in Colin's life,' Cofer stated.

'She had to be portrayed as a jealous psycho to explain motive.' 

But jealousy, Coffey added, does not equal murder, calling Armstrong has normal human emotions of not trusting a cheating boyfriend. 

Armstrong's lawyer reminded the jury DNA taken from Wilson's body to see if she had been raped the night of her murder was never tested.

Neither was unknown DNA on Wilson's bike. 

'The truth of the matter is that APD didn't want a single piece of evidence in front of you that points away from Kaitlin Armstrong. They don't want a single piece of evidence that is inconsistent with their case,' her lawyer went on. 

Cofer also addressed Armstrong's two attempts to escape, calling her 'terrified,' and adding she could have been afraid she would be murdered next.

While saying Armstrong did not kill Wilson, Cofer added he doesn't know who the real killer is. 

'Anyone could have entered that unlocked apartment,' the defense attorney said.

Armstrong faces 99 years in prison if convicted. 

'"Not guilty" doesn't mean "innocent;" it can mean something else,' pleaded Armstrong's lawyer.
