WASHINGTON, Sept 15, (AP): Family and friends of the 22-year-old accused of fatally shooting conservative activist Charlie Kirk described his politics as veering left in recent years as he spent large amounts of time scrolling the "dark corners of the internet,” Utah Gov Spencer Cox said Sunday. Investigators were still piecing together information about the suspect, Tyler Robinson, and not yet ready to discuss a potential motive. But Cox noted that Robinson, who is not cooperating with law enforcement, disliked Kirk and may have been "radicalized” online.

Kirk founded Turning Point USA to bring more young, conservative evangelical Christians into politics as effective activists, and he was a confidant of President Donald Trump, leading to a flood of tributes that included a vigil Sunday night at the Kennedy Center in Washington. Kirk, a 31-year-old father of two, became prominent in part through his speaking tours, and he was shot Wednesday while speaking at Utah Valley University.

"There clearly was a leftist ideology,” Cox said on NBC’s "Meet the Press,” citing interviews with Robinson’s relatives and acquaintances. "Friends have confirmed that there was kind of that deep, dark internet, the Reddit culture, and these other dark places of the internet where this person was going deep.” He pointed to references found engraved on the ammunition used to kill Kirk, which included anti-fascist and meme-culture language.

Court records show that one bullet casing had the message, "Hey, fascist! Catch!” A Republican who has called on all partisans to tone down their rhetoric following the attack, the governor added: "I really don’t have a dog in this fight. If this was a radicalized MAGA person, I’d be saying that as well.” Cox stressed on several Sunday morning news shows that investigators are still trying to pin down a motive for the attack on Kirk, a Trump confidant.

The governor said more information may come out once Robinson appears in court Tuesday. Cox said the suspect's partner was transgender, which some politicians have pointed to as a sign Robinson was targeting Kirk for his anti-transgender views. But authorities have not said whether it is relevant as they investigate Robinson’s motive. "The roommate was a romantic partner, a male transitioning to female,” Cox said. "I can say that he has been incredibly cooperative, this partner has been very cooperative, had no idea that this was happening.”
