Charlie Kirk murder suspect pleads not guilty as judge clears way for death penalty trial

A 23-year-old Utah man has pleaded not guilty to the murder of conservative activist Charlie Kirk – as a judge ruled prosecutors can seek the death penalty at trial.

Tyler Robinson denies aggravated murder, a capital offence in Utah, and six other charges in connection with the shooting of Kirk at a campus event on 10 September 2025.

Defence lawyers had tried to have the death penalty taken off the table, but prosecutors argued that aggravating factors, such as firing into a crowd in the presence of children, warranted a capital trial.

Turning Point USA co-founder Kirk, 31, was shot in the neck while speaking at Utah Valley University in Orem.

The defendant, wearing a grey suit and occasionally consulting with his lawyers, appeared in court in the city of Provo on Tuesday.

Kirk's widow, Erika, the mother of their two children, and his parents, ⁠Robert and Kathryn, were also at the hearing.

In a statement shared afterwards, the Kirk family said the judge's decision "marks an important step" in their "pursuit of justice".

"Every step in this process carries the weight of all that Charlie's murder has taken from his family, especially his children who will grow up without their father," the statement added.

Closing arguments followed a five-day preliminary hearing in July, during which prosecutors outlined their evidence to show probable cause for trial.

That included DNA allegedly tying Robinson to the murder weapon and other items recovered at the scene; confessions he allegedly made to loved ones; and a taped video statement from his roommate and romantic partner, Lance Twiggs.

"There is a mountain of evidence that proves that he is the shooter," prosecutor Ryan McBride told the court on Tuesday, outlining video that he said showed Robinson "dressed to kill" on campus on the day of the shooting.

"We know that the defendant is the shooter… first, because of the video evidence; second, because of the DNA; third, because of his admissions; and fourth, because of circumstantial evidence," McBride said.

Prosecutors said the accused, a former apprentice electrician, was in a relationship with his roommate and regarded Kirk's conservative views, particularly on transgender issues, as "repugnant" - which they argued was the motive.

On Tuesday, prosecutors also outlined "aggravating" factors - accusing the defendant of "gambling with the lives of others" when he allegedly fired towards Kirk, who was surrounded by other people.

"He was playing, in effect, a game of ballistic roulette," prosecutor Chad Grunander said.

"It's been 356 days since Tyler Robinson assassinated Charlie Kirk," Grunander added. "It's time for him, the defendant, to be bound over for trial and arraigned. Today."

Defence lawyers attempted to sow doubt about the prosecution's evidence.

During July's hearing, they raised questions about procedure and the credentials of experts who testified. Robinson's lawyers have repeatedly objected to cameras livestreaming court proceedings.

Judge Tony Graf again listened to arguments on the issue during a sealed hearing on Tuesday morning before closing arguments began - but he ruled in favour of transparency in a case that has sparked conspiracy theories.

On Tuesday, the defence sought to downplay the aggravating factors outlined by prosecutors - arguing that no bullets hit anyone in the crowd apart from Kirk.
