Prosecutors Accuse Charlie Kirk Assassination Defense of Misleading Public on Key Evidence

Utah prosecutors have fired back against defense attorneys representing Tyler Robinson, the man accused of assassinating conservative activist Charlie Kirk, alleging they deliberately misled the public about crucial ballistic evidence in the high-profile case.

In a strongly-worded court filing, Deputy Utah County Attorney Christopher Ballard accused Robinson’s defense team of strategically omitting key information that subsequently went viral in media reports, fueling unsubstantiated conspiracy theories about Kirk’s murder.

The dispute centers around statements made by Robinson’s attorneys regarding ballistic evidence examined by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). The defense claimed in court documents that “the ATF was unable to identify the bullet recovered at autopsy to the rifle allegedly tied to Mr. Robinson,” suggesting potential reasonable doubt in the case.

However, Ballard contends this representation was deliberately misleading because it excluded crucial context. “The ATF was unable to identify or exclude the bullet as having been fired from the rifle,” Ballard emphasized in his response, adding that the defense reinforced the misleading impression by suggesting they might present the ATF’s findings as “exculpatory evidence.”

The prosecution’s filing came in response to a defense motion seeking sanctions against prosecutors for speaking about the case outside the courtroom. Ballard argues that while court rules and a gag order limit what can be discussed publicly, these same rules permit attorneys to “set the record straight” when information has been misrepresented.

Judge Tony Graf Jr. ultimately unsealed the ATF report to provide the public with direct access to the source material. The report’s appendix clarified that “inconclusive” findings indicate “an examiner’s opinion that there is an insufficient quality and/or quantity of individual characteristics to identify or exclude” a bullet from having been fired from a specific weapon.

Ballistics experts have noted to media outlets that it’s not unusual for bullets to fragment upon impact with human tissue, making definitive identification difficult or impossible in some cases.

Despite the inconclusive ballistic match, prosecutors have substantial evidence linking Robinson to the crime. Law enforcement recovered a spent casing consistent with both the bullet and the alleged murder weapon—a Mauser rifle belonging to Robinson’s grandfather.

According to investigators, Robinson allegedly positioned himself on a rooftop across from where Kirk was speaking at Utah Valley University on September 10, 2025, and fired a single fatal shot. Campus police found physical evidence on the gravel rooftop “consistent with a sniper having lain there—impressions in the gravel potentially left by the elbows, knees and feet of a person in a prone shooting position.”

The shooting occurred in front of approximately 3,000 people who had gathered to hear Kirk speak during his “American Comeback Tour.” Graphic video captured the moment the bullet struck Kirk in the neck, resulting in his death.

Police later discovered the rifle wrapped in a blanket in a wooded area near campus. Text messages between Robinson and his romantic partner, Lance Twiggs, allegedly reference plans to retrieve the weapon. “Stuck in Orem for a little while longer yet,” Robinson reportedly wrote hours after the murder. “Shouldn’t be long until I can come home, but I gotta grab my rifle still.” Twiggs, who is cooperating with investigators, has not been charged with any crime.

The legal battle has additional layers of complexity. Robinson’s defense team has previously raised concerns about media coverage potentially jeopardizing their client’s right to a fair trial and has a pending motion to prohibit news cameras from future court proceedings.

If convicted of aggravated murder, Robinson could face the death penalty, making this one of the most closely watched criminal cases in the country.

The judge has yet to rule on the defense’s motion for sanctions or their request to have prosecutors turn over internal communications, which Ballard argues are protected as privileged work products.
