PROVO, Utah — DNA belonging to accused Charlie Kirk killer Tyler Robinson and his former lover and roommate, Lance Twiggs, was allegedly found on a towel and screwdriver collected as evidence in the assassination investigation, according to testimony.
Robinson, 23, is accused of using the towel to hide the suspected murder weapon in a wooded area near Utah Valley University on Sept. 10, 2025.

Investigators have not publicly explained the suspected purpose of the screwdriver. However, police testified during Robinson’s preliminary hearing this week that it was discovered near what they described as a sniper’s position overlooking the Turning Point USA gathering.
Both Robinson and Twiggs submitted buccal swabs to investigators, allowing law enforcement to develop complete DNA profiles for comparison, according to the testimony.
Robinson’s preliminary hearing opened Monday and is expected to continue throughout the week. Prosecutors must show probable cause for the case to proceed to trial on multiple charges, including aggravated murder, an offense that could make Robinson eligible for the death penalty if convicted.

David Hull, of the Utah Department of Public Safety, returned to the witness stand Tuesday morning as prosecutors played surveillance video they allege shows Robinson making his way around campus before and after the shooting, as well as coming and going in his Dodge Challenger.
The second witness of the day, Sgt. Jennifer Faumuina with the State Bureau of Investigations, led the evidence response team processing the scenes at UVU after the shooting.
Faumuina testified that her team recovered a screwdriver from the campus’ Losee Center rooftop, where Robinson is alleged to have fired the shot that killed Kirk.

She also testified that her team recovered the suspected murder weapon, a Mauser 98 bolt-action rifle wrapped in a dark-colored towel nearby. It had been retrofitted to fire .30-06 rounds, consistent with the caliber of bullet fragments recovered during Kirk’s autopsy.

Faumuina testified that both the towel and the screwdriver had DNA consistent with the same two males — Robinson and Twiggs.
In a handwritten note and text messages, Robinson is alleged to have confessed to the crime to Twiggs, who lived with him at the time and is cooperating with investigators. Twiggs has not been charged with a crime, and the alleged presence of his DNA on the evidence is expected to strengthen the case against Robinson.

Later Tuesday, FBI forensic analyst Amanda Bakker testified that Robinson is likely the majority donor in mixed DNA samples found on both items. Twiggs is believed to be the minority contributor on both.
Prosecutor Ryan McBride objected multiple times during Bakker’s lengthy questioning from defense attorney Michael Burt, arguing that the defense went well “beyond the scope of determining probable cause.”
At one point, Judge Tony Graf Jr. asked how far he intended to go in a line of questioning, to which Burt responded he had one more question before moving on.

“I’ll hold them to that,” McBride said, prompting laughter inside the courtroom.
As the DNA questioning dragged on for much of the afternoon, Erika Kirk at one point shook her head as she listened to Burt grilling Bakker.
Observers in the gallery, including Erika Kirk, intently watched as Bakker explained a graph displaying specific DNA markers.
Kirk leaned forward and tilted her head as she listened to testimony.
Robinson was also listening and fidgeting. A member of Robinson’s family yawned.
Kirk’s father occasionally took notes.
Robinson has not yet entered a plea.
If prosecutors prevail in establishing probable cause, which experts say is widely expected, he would be asked to do so.
“Barring the prosecutor somehow forgetting how to get to the courthouse, there’s no realistic chance the state fails to establish probable cause,” Maryland attorney Randolph Rice, who represented the family of Rachel Morin, told INC News Tuesday.
