Charlie Kirk was killed on a college campus in September.
Six months later, a federal agency can't prove the suspect they say killed him did it how they said.
Now the FBI is running a second round of tests – and the people responsible for that delay aren't explaining why.
ATF Could Not Match the Bullet Fragment From Kirk's Autopsy to the Rifle
Court documents filed March 27 by Tyler Robinson's defense attorneys contain a stunning admission buried on page 22. The ATF – the federal agency responsible for firearms forensics – conducted a ballistics analysis and came back empty.
Their own report states the agency was "unable to identify the bullet recovered at autopsy to the rifle allegedly tied to Mr. Robinson."
That rifle is a Mauser Model 98, a decades-old bolt-action weapon that prosecutors say Robinson used to fire a single .30-06 round into Kirk's neck on September 10, 2025. They maintain Robinson's DNA was found on the trigger and that cartridge casings near the scene were consistent with the rifle.
But the bullet that actually killed Charlie Kirk? The ATF can't connect it to that gun.
Robinson's attorneys are now pushing to call the ATF firearms analyst as a witness – not for the prosecution, but for the defense.
The FBI Is Running a Second Analysis – But Close Kirk Friend Candace Owens Says We’ve Seen Their Kind Before
Here's what the lawyers found when they started digging through discovery: the FBI is now running a second comparative bullet analysis and a separate bullet lead analysis.
The ATF handed over a summary but is sitting on the full case file – the protocols, the raw data, everything the defense needs to evaluate whether the agency even ran the test correctly.

Defense attorneys also received a hard drive containing 700 hours of video, 31 hours of audio, and 600,000 data files. They haven't had time to review them. The Utah County Attorney's Office – to their credit – appears to be pushing the federal agencies to produce what's owed. It's the ATF and FBI that are dragging their feet six months after Charlie Kirk was killed.
The defense also flags that forensic reports show multiple DNA profiles on some items recovered from the scene – not just Robinson's. Prosecutors call it the routine complexity of mixed DNA samples. Maybe. But that determination requires forensic biologists, geneticists, and statisticians to review before anyone can say so with confidence – and those experts haven't finished their work either.
What "Unable to Identify" Actually Means in the Charlie Kirk Case
Retired federal agents were quick to point out that "unable to identify" is not the same as "ruled out." Retired FBI supervisory agent Jason Pack put it plainly: "That's a finding of inconclusiveness, not exoneration."
Here's why. Ballistics analysts look for microscopic markings pressed into a bullet's surface as it travels through a gun barrel – striations as unique as fingerprints.
Inconclusive is not innocent. But it is not proof either.
Prosecutors are seeking the death penalty.
But they have to prove guilt beyond a reasonable doubt – that’s how the American justice system is supposed to work.
The Charlie Kirk Murder Case Has a Problem Nobody in Washington Will Name
What has changed is this: the two most powerful law enforcement agencies in America have been working this case for six months and still can't close the loop on the most fundamental piece of evidence – the bullet that killed Charlie Kirk.
That should bother you.
Not just because Tyler Robinson might be innocent.
But because if the case is as airtight as prosecutors want you to believe, the ATF and FBI should be able to prove it. Instead, they're sitting on files, running additional tests, and leaving the family of a murdered conservative leader waiting for answers that a competent federal investigation should have delivered months ago.
The FBI ran the same agencies that spent years hunting political enemies of the Left while this kind of basic forensic work goes unfinished. Someone at the ATF and FBI needs to explain why – out loud, on the record – before this case gets anywhere near a jury.
Charlie Kirk deserves an airtight case. So far, the federal agencies investigating his murder haven't built one.
