An analysis from the federal Bureau of Alcohol, Tobacco, Firearms and Explosive (ATF) could not conclusively connect a bullet fragment recovered during Charlie Kirk’s autopsy to the rifle found near the scene of the rightwing political activist’s killing – and the FBI is running additional tests, lawyers for Kirk’s accused murderer said in recent court filings.
In the court filings, Tyler Robinson’s defense team also asked for a delay to a preliminary hearing scheduled in May, saying they need time to review the bullet analysis as well as an enormous amount of other material that could contribute to the suspect’s defense.
The ATF’s bullet analysis report has been kept private, but attorneys have cited snippets in other public filings that say the results were inconclusive.
The defense said in its motion that it may try to use the analysis to clear Robinson of blame during the preliminary hearing while prosecutors aim to show they have enough evidence against him to proceed with a trial.
Hunting rifles like that are usually going to make a small entrance wound and larger exit wound. I haven't seen exactly what happened to kirk because I don't like to watch people die. But I can say from experience with deer hunting that it's plausible for that rifle to make a narrow wound channel through a person, while being extremely deadly to them, not making a huge wound outside.
Basically those high powered rounds are made to penetrate well through large animals, tougher than humans. Expanding and deforming of the round is intended to begin well after penetration, unlike the way handgun bullets are designed.
So I think it's totally possible that Robinson did it even though the bullet isn't able to be matched
