In Provo, Utah, a significant development occurred in the investigation into the assassination of Charlie Kirk. Authorities discovered that a towel and screwdriver found during the investigation contained DNA from Tyler Robinson, the suspect, and his former lover and roommate, Lance Twiggs. Robinson is accused of using the towel to hide the murder weapon in the woods close to Utah Valley University on September 10, 2025. He is charged with the fatal shooting of the 31-year-old Kirk during a Turning Point USA event at the university.
Discovery and DNA Evidence
The police are unclear about the purpose of the screwdriver, but they testified this week that it was found near an alleged sniper’s position overlooking the TPUSA event. Both Robinson and Twiggs provided buccal swabs, helping to establish their full DNA profiles. The preliminary hearing for Robinson began on Monday and is expected to last all week. Prosecutors aim to establish probable cause for trial on multiple charges, including aggravated murder, which can lead to the death penalty.
Preliminary Hearing Insights
David Hull from the Utah Department of Public Safety testified that surveillance video allegedly shows Robinson moving around the campus before and after the shooting and in his Dodge Challenger. Sgt. Jennifer Faumuina from the State Bureau of Investigations testified that her team recovered the suspected murder weapon, a Mauser 98 bolt-action rifle, along with the towel on campus. The rifle was retrofitted to fire .30-06 rounds, consistent with bullet fragments found during Kirk’s autopsy. Faumuina also testifies that the DNA on both the towel and screwdriver is consistent with Robinson and Twiggs.
Confession and Cooperation
Robinson allegedly confessed to Twiggs in a handwritten note and text messages. Twiggs, who lived with Robinson at the time, is cooperating with investigators and has not been charged, although his DNA presence is expected to strengthen the case against Robinson.
FBI Analysis and Courtroom Dynamics
Later, FBI forensic analyst Amanda Bakker testified that Robinson is likely the majority contributor in mixed DNA samples on the items. Twiggs is thought to be the minority contributor. During intense questioning by defense attorney Michael Burt, Prosecutor Ryan McBride objected several times, claiming it exceeded the scope of determining probable cause. Judge Tony Graf Jr. intervened during the lengthy questioning.
Observers, including Erika Kirk, watched attentively as Bakker explained the DNA evidence. Robinson was also present, appearing restless, while Kirk’s father took notes.
Robinson has not yet entered a plea. Should prosecutors establish probable cause, Robinson will be required to do so. Legal experts believe it is highly likely that probable cause will be established, allowing the process to move forward.
