Utah Governor Spencer Cox has opened up about potential motives of the alleged Charlie Kirk shooter, pointing to gaming and “dark internet” culture as potential factors.

Meanwhile, investigators are also looking into if the fact the roommate of Tyler Robinson, Kirk’s alleged shooter, was a romantic partner of Robinson and transitioning from male to female, was a factor in last week’s assassination.

“Yes. I can confirm that. I know that has been reported, and that the FBI has confirmed that as well – that the roommate was a romantic partner, a male transitioning to female,” Cox said in an interview with CNN’s Dana Bash on State of the Union.

The roommate, Cox added, “has been incredibly cooperative, had no idea that this was happening, and is working with investigators right now”.

Asked by Bash whether the roommate’s status was relevant to the investigation and a potential motive, Cox said it was “easy to draw conclusions” but declined to speculate.

“I know everybody wants to know exactly why, and point the finger. And I totally get that,” Cox said.

“I do too, and so I just want to be careful, as I haven’t read all of the interview transcripts, and so we’ll have to wait and see what comes out.”

Cox further elaborated on how investigators have determined that Robinson had been radicalized, pointing to gaming and “dark internet” culture as potential factors that contributed to a shift.

Cox suggested things changed for Robinson after he dropped out of Utah State University.

“It seemed to happen kind of after that — after he moved back to the southern part of Utah. Clearly, there was a lot of gaming going on, friends that have confirmed that there was kind of that deep, dark internet, Reddit culture and these other dark places of the internet where this person was going deep. You saw that on the casings. … the meme-ification that is happening in our society today,” he told NBC.

In an interview with ABC’s “This Week” with Martha Raddatz, Cox also confirmed reports that acquaintances were joking online with Robinson about photos released by the FBI during the manhunt.

“Those conversations definitely were happening. And they did not believe it was actually him — it was all joking until he admitted that it actually was him,” he said.

Official charges, Cox said, will be filed tomorrow.
