Tyler Robinson Defense Challenges Forensic Evidence in Charlie Kirk Murder Case

Forensic examiners returned an inconclusive result on the bullet fragment from the scene, while a shell casing positively matched the suspected rifle.

In a peer-reviewed study, 23% of all forensic firearms comparisons returned inconclusive results. For bullets fired from different guns, that rate reached 34%.

A 2022 FBI Laboratory accuracy study found forensic firearms examiners reached a correct identification decision roughly 99% of the time when they did not return an inconclusive result.

Robinson's DNA was found on the rifle and shell casings recovered near the scene. DNA from five or more contributors was also detected on some of the same items.
