Has any later public autopsy or forensic ballistics report been released that identifies the caliber of the bullet in Charlie Kirk's death?

1. What official records say — nothing specific about caliber

Available official updates and law‑enforcement briefings confirm an active federal and local investigation into the Utah Valley shooting, and the FBI has publicly posted investigation updates, reward notices, and video releases, but those releases do not include an autopsy text or a ballistic report stating the bullet caliber ^[3]. Reporting compiled by fact‑check teams and regional news outlets explicitly states that no full autopsy report has been published and that authorities have not confirmed in public whether a bullet was recovered at the hospital or during an autopsy, nor released details on its caliber or ballistic markings ^[1].

2. Public claims and spokesperson statements — asserted but unverified

Several partisan or organizational spokespeople and secondary outlets have circulated medical or internal accounts about the wound, including a statement attributed to Turning Point USA’s Andrew Kolvet — via other outlets and commentary — that a surgeon told him the bullet “did not exit” and lodged near the skin, and that the wound’s behavior was surprising given its alleged caliber; those claims have appeared in commentary pieces and social reporting but are not backed by a published autopsy or forensic report in the public record ^[2]. WinterWatch and other fringe pieces have echoed interpretations about “small caliber” wounds or internal TPUSA briefings, but they too concede there is no publicly released autopsy to confirm such specifics ^[4].

3. What forensic processes authorities say they’ve done — labs examined evidence but results not public

At a public press event authorities stated that forensic evidence had been evaluated at FBI laboratories in Quantico as well as by state and local agencies, indicating formal ballistic and forensic workflows have been undertaken; however, officials also acknowledged that evidence processing remains ongoing and that detailed laboratory findings had not been released to the public as of those briefings ^[1]. The FBI’s public pages and press releases about the investigation include procedural updates and video releases but do not publish underlying autopsy reports or ballistic identifications ^[3].

4. Why the absence of a public caliber ID matters — official confirmation vs. rumor

Because no autopsy report or laboratory ballistic report identifying caliber has been released, assertions about the bullet’s size, whether it exited the body, or whether it matched a recovered firearm remain unverified in public records; that gap has allowed competing narratives to spread, from claims that the bullet was “small caliber” to counterclaims that a high‑power rifle was used, but those narratives currently rest on secondary statements rather than primary, publicly available forensic documentation ^{[1] [4]}. Reporting from medical‑analysis outlets underscores that no hospital or medical examiner has published operative notes, imaging, or the autopsy text that would settle trajectory, exit wounds, or the presence and description of a recovered projectile ^[2].

5. Bottom line and limitations of available reporting

The plain, sourced conclusion is that no later public autopsy or forensic ballistics report identifying the caliber of the bullet in Charlie Kirk’s death has been released; investigators have processed evidence in federal and state labs, and spokespeople and partisan outlets have offered claims or interpretations, but those claims are not the same as published forensic documentation available to independent scrutiny ^{[1] [3] [2]}. This account is limited to the documents and reporting currently in the public record; if authorities subsequently publish the autopsy or a ballistic report, that primary documentation would be the definitive source for caliber identification—until then, caliber remains officially unreleased.
