The boyfriend at the center of the ‘killer’ yoga teacher murder trial was so agitated as he left court yesterday that he went out of his way to stamp on a press cameraman’s foot. 

Colin Strickland, 37, had been testifying against his ex, defendant Kaitlin Armstrong, when he stormed out of the court on his way back to his car, trailed by the media. 

In a video filmed by NewsNation’s Alex Caprariello, the cameraman can be heard yelling ‘ouch!’ after Strickland’s outburst. 

It was his second such assault on a member of the press. He was also seen batting away a news camera while inside the courthouse earlier in the day. 

The cameraman has not yet been named, but Caprariello reports that he intends to press charges against Strickland. 

Strickland spent yesterday testifying about how jealous a girlfriend Armstrong was.

She routinely blocked women’s numbers in his phone without his knowledge, and was particularly hung up about his relationship with the murder victim, Moriah ‘Mo’ Wilson. 

He claims the pair were just friends when she died, but admits lying to Armstrong about spending the day with her. He also stored her phone number under a fake name to avoid Armstrong’s wrath. 

In March 2022, Armstrong was furious after seeing an Instagram photo of the pair completing a cycling race.

‘Send my love to Mo,’ she quipped.

‘Can you please stop,’ he begged her.

On the day of the murder, when he was swimming with Wilson, Strickland told Armstrong he had been to drop off flowers at a friend’s house.

‘Hey! Are you out? I went to drop some flowers for Alison at her son’s house up north and my phone died.

Heading home unless you have another food suggestion,’ he said. 

Last week, jurors were played Ring surveillance camera footage from a neighbor in which Wilson could be heard screaming. 

Three gunshots were heard. 

Prosecutors say Armstrong, using a gun Strickland purchased for her, shot Wilson twice in the head and once through the heart. 

It is believed that she then fled the apartment on Wilson’s bicycle, which was found dumped in bushes behind her apartment. 

Armstrong fled Texas after an initial police interview. 

She flew to Costa Rica, where she claims she was merely teaching yoga. 

Moriah ‘Mo’ Wilson was shot dead in Austin on May 11th. She had just returned home from an evening swim with Strickland, who she had at one time been romantic with 

After Wilson and Strickland’s secret meet-up, Armstrong’s 2012 Jeep Grand Cherokee was spotted driving outside the Austin home of Wilson’s friend, where the cyclist was murdered

Authorities said at the time she paid for a nose job and dyed her hair brown after fleeing the US, using her sister’s passport to fly from the US. Armstrong also used several aliases while on the run, using the name ‘Ari’ to woo a man she met in a tattoo shop while on the run. 

Police arrested the her after an anonymous tip and surveillance footage outside of Wilson’s apartment supposedly showed the yoga instructor’s car. 

She was arrested in July and brought back to Austin. A few weeks before her trial commenced, she tried to run away again during a visit to a doctor’s office. 

However, Armstrong  only managed to stay on the lam for about 10 minutes before deputies caught up to her. 

The officers said she ran more than a block into a neighborhood, but remained in their sight the entire time. 

The amateur yoga teacher was taken to the Dell Seton Medical Center after the attempted escape.
