Authorities say the mother of the man accused of fatally shooting conservative commentator Charlie Kirk told investigators her son underwent a dramatic political shift in the year before the attack, increasingly expressing support for gay and transgender rights and clashing with his father over ideology.
Prosecutors have charged 22-year-old Tyler Robinson with aggravated murder and multiple related offenses in the Sept. 10, 2025, slaying at Utah Valley University, and filed a notice of intent to seek the death penalty. In charging documents, prosecutors allege Robinson intentionally targeted Kirk "because of his political expression," and include a chain of text messages in which Robinson appears to admit planning and carrying out the attack.
Video and witness accounts show Kirk, a 31-year-old father of two and founder of Turning Point USA, speaking in a packed UVU courtyard when a shooter fired from a rooftop roughly 200 yards away. Kirk died from the gunshot wound. Prosecutors say Robinson’s parents recognized him in surveillance images published after the shooting; the father confronted his son and persuaded him to surrender to police.
Court filings quote Robinson as telling his parents, "I couldn’t go to jail and just wanted to end it," and saying of Kirk that he "spreads too much hate." In a set of text messages disclosed by Utah County District Attorney Jeff Gray, Robinson allegedly wrote after the shooting, "I had enough of [Kirk’s] hatred. Some hate can’t be negotiated out." Prosecutors say those messages also detail steps Robinson took to discard clothing and the rifle and urge his partner to delete messages and remain silent if questioned by authorities.
Robinson faces two counts of obstruction of justice for allegedly concealing the rifle and discarding clothing, two counts of witness tampering for encouraging his roommate to delete texts, a count of committing a violent offense in the presence of a child, and aggravated murder. Law enforcement reported recovering a Mauser .30-06 rifle wrapped in a towel in woods near the university.
Photographs viewed by news outlets showed Robinson as a high-achieving high school student who graduated in 2021 and later briefly attended Utah State University for one semester as a pre-engineering major. Utah State University confirmed in a statement that Robinson "briefly attended" and that his coursework was consistent with a pre-engineering major. More recently he had enrolled in an electrical apprenticeship program at Dixie Technical College, officials said.
Family photos released to media depict vacations and moments with siblings, but court documents and interviews with Robinson’s mother portray a young man who shifted politically over the past year and who entered a relationship with a romantic partner identified by investigators as a biological male undergoing transition to female. Prosecutors said that relationship coincided with the changes his mother described and that the partner is cooperating with investigators.
FBI officials and local prosecutors said they are investigating whether Robinson had any accomplices or connections to broader groups. FBI Deputy Director Dan Bongino told a television program investigators were examining whether anyone else may have known of or assisted with the attack and said available data suggested an "ideology had infected him and had taken over." Law enforcement has said those lines of inquiry remain under investigation.
Robinson appeared virtually in Utah court on Sept. 16, 2025. Court papers allege he told acquaintances he had made threats against Kirk before the shooting, a claim authorities said they were still examining. Prosecutors also allege Robinson discussed the attack in detail in the post-shooting texts, describing how he discarded the rifle and clothing and stating he had planned the assault "for a bit over a week."
The killing has drawn attention across political and law enforcement circles because Kirk was a high-profile conservative voice and the attack occurred during a public appearance. Authorities emphasized they were treating the case as a criminal investigation focused on motive and any potential links to others, while prosecutors moved to bring the full slate of charges and pursue capital punishment under Utah law.
As the investigation continues, authorities have not released a formal motive beyond what appears in court filings and the disclosed messages. Officials cautioned that allegations in charging documents are not proof of guilt; Robinson will face his day in court as the legal process proceeds.
District attorneys said they will present evidence in court to support the charges and the notice seeking the death penalty. Investigators continue to review digital data, surveillance, and witness statements as they work to corroborate the timeline and determine whether others were involved. Appeals for comment from Robinson’s defense representatives were not immediately answered. Representatives for Turning Point USA and Kirk’s family did not immediately respond to requests for comment.
