Robinson is accused of being the shooter who killed Kirk at an event at Utah Valley University

Lawyers for Tyler Robinson, the man accused of killing Charlie Kirk, argue in a new court filing that authorities have been unable to link the bullet that killed the conservative activist to a gun "allegedly tied" to their client.

The claim is found in a motion to delay an upcoming preliminary hearing scheduled for May, during which a judge will decide whether the case will proceed.

Robinson's defense team claims that an Alcohol, Tobacco & Firearms (ATF) summary report indicated that the agency "was unable to identify the bullet recovered at autopsy to the rifle allegedly tied to Mr. Robinson."

"Although the State has not indicated an intent to produce this report at the preliminary hearing, the defense may very well decide to offer the testimony of the ATF firearm analyst as exculpatory evidence," the filing states.

"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," it continues. "The State has also indicated that the FBI is in the process of conducting a second comparative bullet analysis, as well as a bullet lead analysis, but that these analyses are not yet complete."

Robinson is accused by authorities of killing Kirk while he was speaking at a Turning Point USA event on the campus of Utah Valley University in Orem, Utah on Sept. 10, 2025.

Robinson has been charged with multiple felonies, including aggravated murder. He has not yet entered a plea.
