Defense attorneys seek to block trial in Charlie Kirk assassination case
Paul Mauro, a retired NYPD inspector, delves into the defense’s efforts to halt the trial of suspect Tyler Robinson, implicated in the murder of Charlie Kirk in Utah. The prosecution has built a compelling case, presenting crucial evidence such as surveillance footage, ballistics analysis, a Dremel tool, DNA proof tying Robinson to the rifle, and testimony from his roommate, Lance Twiggs.
Prosecutors in Utah are advocating vigorously to ensure Tyler Robinson stands trial for every charge linked to Charlie Kirk’s murder. They argue that the amassed evidence compellingly points toward Robinson’s guilt, countering the defense’s attempts to eliminate the death penalty as a feasible outcome.
This Tuesday, in a detailed 19-page response, the prosecution addressed the defense’s request. They appealed to Judge Tony Graf to dismiss the defense’s plea to discard the aggravating factor that might lead to Robinson facing capital punishment.
The defense team challenged the prosecution by claiming that they failed to prove the shooting posed a significant risk of death to anyone beyond Charlie Kirk.

Prosecutors said the evidence shows otherwise, arguing Robinson allegedly fired his grandfather’s high-powered rifle toward a crowd of thousands, with several people in the line of fire or close to Kirk.
They rejected the defense’s argument that the bullet traveled above the crowd, saying people near Kirk were still within the “zone of danger” created when Robinson allegedly fired the rifle.
“The evidence here easily establishes at least probable cause” that Robinson knowingly created a great risk of death to others, prosecutors wrote. They said the evidence is “more than sufficient to support a finding beyond a reasonable doubt.”
The state also took aim at the defense’s broader challenge to the evidence presented during Robinson’s preliminary hearing.

“Defendant does not challenge the substance of the evidence demonstrating that he was the person who crawled to the sniper’s perch on the Losee Building rooftop, fired the fatal shot that killed Mr. Charlie Kirk, hid the rifle in a wooded area, got rid of some of the clothing he was wearing, and told his roommate to delete their texts about the shooting,” prosecutors wrote.
Prosecutors also accused Robinson’s attorneys of relying on case law that was later rejected by the Utah Supreme Court while failing to alert the judge to those later decisions.
“This blatant omission violates counsel’s duty of candor to the court,” prosecutors wrote.
The filing also defends a witness-tampering charge involving Robinson’s roommate and an allegation that Robinson committed a violent offense in the presence of a child.

Prosecutors also argue there is evidence Kirk was targeted because of his political expression, pointing in part to a cartridge engraved with the words “Hey fascist, catch.”
Robinson, 23, is accused of fatally shooting Kirk, 31, as he spoke at Utah Valley University on Sept. 10, 2025. Robinson has not entered a plea.
Graf is expected to decide at a Sept. 1 hearing whether prosecutors have shown enough probable cause to send the case to trial.
