An analysis by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) could not conclusively link a bullet fragment found during Charlie Kirk's autopsy to a rifle discovered near the scene of his killing, according to court filings from the defence of accused murderer Tyler Robinson.
The defence team has requested a delay to a preliminary hearing scheduled for May, citing the need to review the bullet analysis and a large volume of other evidence. The ATF report has been kept private, but attorneys have referenced snippets in public filings indicating the results were inconclusive.
The success of forensic ballistics analysis depends on the size and condition of bullet fragments, as experts look for unique microscopic markings left by a gun's barrel. The defence may use the analysis to argue Robinson's innocence at the preliminary hearing, while prosecutors aim to demonstrate sufficient evidence for trial.
Robinson, 22, is charged with aggravated murder in the 10 September shooting of Kirk on the Utah Valley University campus in Orem. Prosecutors intend to seek the death penalty. Robinson has not yet entered a plea.
Prosecutors have said DNA consistent with Robinson's was found on the rifle trigger, a fired cartridge casing, and two unfired cartridges. However, defence attorneys note that forensic reports indicate multiple people's DNA was found on some items, requiring more complex analysis.
Robinson reportedly texted his romantic partner that he targeted Kirk because he 'had enough of his hatred,' prosecutors have said. He is due back in court on 17 April for a hearing on a defence motion to ban cameras from the courtroom.
