The Utah trade school student jailed on suspicion of fatally shooting right-wing activist Charlie Kirk faces formal charges next week, according to the governor, from an act of violence widely seen as a foreboding inflection point in US politics.
Tyler Robinson, 22, was arrested on Thursday night after relatives and a family friend alerted authorities that he had implicated himself in the crime, Governor Spencer Cox said on Friday, telling a press conference, “We got him”.
The arrest capped a 33-hour manhunt for the lone suspect in Wednesday’s killing, which President Donald Trump has called a “heinous assassination”.
Kirk, co-founder of the conservative student group Turning Point USA and a staunch Trump ally, was killed by a single rifle shot fired from a rooftop during an outdoor event attended by 3,000 people at Utah Valley University in Orem, about 65km from Salt Lake City.
A bolt-action rifle believed to be the murder weapon was found nearby, and police released images from surveillance cameras showing a “person of interest” wearing dark clothing and sunglasses.
A break in the case came when a relative and a family friend told the local sheriff’s office he had “confessed to them or implied that he had committed” the murder, Cox said.
Robinson, a third-year student in the electrical apprenticeship programme at Dixie Technical College, part of Utah’s public university system, was taken into custody at his parents’ house, about 420km southwest of the crime scene.
Police collected additional evidence on Friday evening from Robinson’s apartment in St. George, about 8km from his parents’ home near the Arizona border.
Yellow crime scene tape was taken down after FBI and state forensic investigators finished their work, but officers remained outside the apartment on Saturday.
Neighbours put up a “Private Property, No Trespassing” sign at the entrance to the complex, which has been swarmed by reporters.
Robinson was held on suspicion of aggravated murder and other charges that were expected to be formally filed in court early next week, the governor said.
Kirk’s movement, meanwhile, announced on Saturday that a memorial event for Kirk will be held on September 21 at State Farm Stadium in Glendale, Arizona.
‘WATERSHED IN AMERICAN HISTORY’
The killing has stirred outrage among Kirk’s supporters and condemnation of political violence from across the ideological spectrum.
Allies of Kirk have taken to the internet in organised efforts to try to have anyone minimising or mocking his death fired from their jobs; Reuters has so far tallied 15 dismissals or suspensions tied to comments about the killing.
Cox called Kirk’s murder a “watershed in American history” and compared it to the rash of US political assassinations of the 1960s.
He declined to discuss possible motives for the killing. Investigators found messages engraved into four bullet casings, which included references to memes and video game in-jokes.
One casing, according to the arrest affidavit, had been inscribed: “If you read this, you are GAY Lmao”.
Many Republicans, including Trump, have been quick to lash out at the political left, accusing liberals of fomenting anti-conservative vitriol that would encourage a kindred spirit to cross the line into violence – even as the president and his allies routinely invoke violent imagery against their opponents.
State records show Robinson was a registered voter but not affiliated with any political party.
A relative told investigators that Robinson had grown more political in recent years and had once discussed with another family member their dislike for Kirk and his viewpoints, according to an arrest warrant affidavit.
RIGHT, LEFT OR CRAZY?
An expert on democracy and security said it was hard to read too much into the messages left on the shell casings recovered by authorities.
One of the inscriptions read: “Hey fascist! CATCH!” followed by a combination of directional arrows, an apparent reference to a sequence of button presses that unleashes a bomb in a popular video game.
Rachel Kleinfeld, a senior fellow at the Carnegie Endowment for International Peace, said that, in some respects, “the ideological beliefs of the shooter don’t matter. What matters is how they’re taken by society. And if our society chooses to keep pointing fingers, whether the person turns out to be right, left or just unstable, then the violence will grow from the pointing of fingers, regardless of the act itself”.
Kleinfeld said most perpetrators of political violence were not clearly on one ideological side or another, but typically driven by “a hodgepodge of conspiracy beliefs and mental illness”.
Speaking to NBC News on Saturday, Trump did not hold back from blaming his political opponents.
“I’d like to see it (the nation) heal,” NBC quoted Trump as saying in a brief telephone interview.
“But we’re dealing with a radical left group of lunatics, and they don’t play fair and they never did.“
Kirk’s murder comes amid the most sustained period of US political violence in decades.
Reuters has documented more than 300 cases of politically motivated violent acts across the ideological spectrum since Trump supporters stormed the US Capitol on January 6, 2021.
Trump himself has survived two attempts on his life, one that left him with a grazed ear during a campaign event in July 2024 and another two months later, foiled by federal agents.
Democrats have fallen victim, too. In April, an arsonist broke into Pennsylvania Governor Josh Shapiro’s residence and set it on fire while the family was inside.
In June, a gunman posing as a police officer in Minnesota murdered Democratic state lawmaker Melissa Hortman and her husband and shot Democratic state Senator John Hoffman and his wife.
