WASHINGTON (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.”

Utah’s governor says a motive still isn’t pinned down
Cox stressed on several Sunday morning news shows that investigators are still trying to pin down a motive for the attack on Kirk. 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.”
Investigators have spoken to Robinson’s relatives and carried out a search warrant at his family’s home in Washington, Utah, about 240 miles (390 kilometers) southwest of Utah Valley University.
State records show Robinson is registered to vote but not affiliated with a political party and is listed as inactive, meaning he did not vote in the two most recent general elections. His parents are registered Republicans.
The suspect grew up in southwestern Utah
Robinson grew up around St. George, in the southwestern corner of Utah between Las Vegas and natural landmarks including Bryce Canyon and Zion National Parks.
Online activity by Robinson’s mother reflects an active family that traveled widely. In one photo, a young Robinson can be seen smiling as he grips the handles of a .50-caliber heavy machine gun outside a military facility.

A high school honor roll student who scored in the 99th percentile nationally on standardized tests, he was admitted to Utah State University in 2021 on a prestigious academic scholarship, according to a video of him reading his acceptance letter that was posted to a family member’s social media account.
But he attended for only one semester, according to the university. He is currently enrolled as a third-year student in the electrical apprenticeship program at Dixie Technical College in St. George.
Tributes emphasize Kirk’s religious faith
The vigil at the Kennedy Center was among numerous tributes to Kirk that also included moments of silence at professional sporting events. The line of mourners in Washington wrapped around the center. Some people wore suits or summer dresses, while others were dressed in jeans and wore “Make America Great Again” caps.
Seventeen-year-old Domiano Maceri and his mother drove about 50 miles (80 kilometers) from Purceville, Virginia, to attend the Kennedy Center event. He said Kirk helped him find a way to better talk with friends who hold different opinions.
“I definitely feel like I was inspired in different ways,” Maceri said as he waited to get inside. “It definitely gave me confidence to speak to my friends about my beliefs more.”
Speakers included White House press secretary Karoline Leavitt, Director of National Intelligence Tulsi Gabbard, two House members whose remembrances of Kirk were briefly stalled when they teared up, and House Speaker Mike Johnson.
“Father, help us remember the principles of your word that Charlie worked every day -- to advance that we not return evil for evil but we overcome evil with good,” Johnson prayed.
At Dream City Church in Phoenix, where Kirk hosted one of his “Freedom Night in America” gatherings, attendees viewed clips of the conservative activist discussing his desire to be “remembered for courage for my faith.”
During a question-and-answer session, a church pastor, Angel Barnett, called on the crowd to honor Kirk by carrying on his message.
“The left is nervous,” Barnett said. “And they’re concerned because they’ve lost control. Charlie started that, and we will continue it.”
Added church panelist Brandon Tatum: “These cowards thought that they could end or eliminate the movement.”
“They just made it bigger. They just made it stronger.”
