Tyler Robinson, 23, is accused of the aggravated murder of conservative activist Charlie Kirk on the Utah Valley University campus on Sept. 10. During a Wednesday preliminary hearing, prosecutors presented DNA evidence and text messages, while defense attorneys questioned the reliability of the forensic testing used to link Robinson to the suspected murder weapon.
What evidence was presented in court?
State Bureau of Investigation Agent Jennifer Faumuina testified that DNA found on a towel used to wrap the suspected murder weapon—a bolt-action rifle with one spent round—matched Lance Twiggs and “very likely” Robinson.

Court documents filed last September state that Robinson admitted to the crime in a text message to Twiggs on the day of the shooting. When Twiggs asked if he was the shooter, Robinson reportedly replied, “I am, I’m sorry.”
Authorities also alleged that Twiggs found a note under Robinson’s computer keyboard that read, “I had the opportunity to take out Charlie Kirk and I’m going to take it.”
How did investigators identify the suspect?
State Bureau of Investigation Agent Brian Davis testified that surveillance footage from the Utah Valley University campus showed a man believed to be Robinson wearing a burgundy T-shirt, jeans, Converse shoes, and a black cap.

A video clip from the Washington County Sheriff’s Office showed Robinson in a holding room wearing the same clothing following his surrender on Sept. 12.
Why is the roommate’s testimony significant?
Prosecutors revealed that Lance Twiggs, Robinson’s roommate, was granted “use immunity” regarding his statements. This means prosecutors have agreed not to use those specific statements against Twiggs in a criminal case.
Twiggs provided recorded video statements during an interview on April 20. These recordings were used in lieu of bringing Twiggs to the preliminary hearing as a live witness.
How is the defense challenging the prosecution?
Defense attorney Michael Burt argued that the DNA analysis cannot definitively match Robinson to the questioned samples. He stated, “She can’t match Mr. Robinson to the questioned samples.”
Forensics expert Lawrence Quarino, a professor and director of the forensic science program at Cedar Crest College, testified that while DNA testing is the “gold standard,” it can be challenged by arguments regarding how material was transferred to a location.
Robinson’s legal team has also unsuccessfully sought to have the death penalty removed from the list of potential penalties.
What are the next steps in the legal process?
The preliminary hearing is expected to conclude on Friday. Following the conclusion, State District Judge Tony Graf must determine if there is enough evidence to proceed to trial.

While Robinson has not yet entered a plea, experts noted that it is likely the case will proceed to trial.
