Newly surfaced court filings are shedding light on a crucial piece of evidence in the killing of Charlie Kirk — and raising fresh questions rather than providing answers.
At the center of the dispute is a damaged bullet fragment recovered from Kirk’s body, per the New York Post.
According to prosecutors, the fragment was too compromised for investigators to definitively link it to the rifle allegedly used by Tyler Robinson.
That uncertainty has fueled speculation online, with some suggesting the fatal shot may not have come from Robinson’s weapon. But prosecutors say the inconclusive finding does not support that claim either.
Court documents referencing analysis by the Bureau of Alcohol, Tobacco, Firearms and Explosives explain that “the result of the comparison was inconclusive.” The report itself has not been publicly released.
The fragment, described as a “bullet jacket fragment,” was collected during an autopsy and compared to a .30-06 hunting rifle allegedly tied to Robinson.
Investigators were unable to determine whether the fragment matched the firearm.
Meanwhile, the Federal Bureau of Investigation is continuing its own forensic review of the ballistic evidence, according to filings from Robinson’s legal team.
Defense attorneys are now seeking to delay a scheduled May 18 hearing, arguing they need more time to review the pending FBI results, along with additional materials from prosecutors.
They have also signaled that the inconclusive findings could become a key part of Robinson’s defense strategy.
“Regarding the firearm evidence, the defense has been provided with an ATF summary report which indicates that the ATF was unable to identify the bullet recovered at autopsy to the rifle allegedly tied to Mr. Robinson,” Robinson’s team wrote.
“The defense may very well decide to offer the testimony of the ATF firearm analyst as exculpatory evidence,” the filing added. “In order to make this determination, it is necessary for the defense and its firearm expert to review the ATF case file and protocols relating to this examination, which have not yet been provided.”
A spokesperson for the Utah County Attorney’s Office, Christopher Ballard, declined to discuss specifics but clarified the meaning of such forensic results.
“When the results of a bullet fragment analysis come back as inconclusive, that means only that the fragment did not contain enough detail for the examiner to determine whether the characteristics on the fragment were consistent with having been fired by a particular firearm.”
Robinson, 22, is accused of fatally shooting Kirk during an event at Utah Valley University on Sept. 10, 2025.
He remains in custody and could face the death penalty if convicted of aggravated murder.
Robinson is scheduled to return to court on April 17, where his attorneys are expected to argue against allowing cameras or recordings during future proceedings.
