Roommate Given Immunity in Charlie Kirk Murder Case as DNA Evidence Faces Defense Scrutiny

Charlie Kirk, conservative activist, was assassinated on Utah Valley University campus on September 10.
I am, I'm sorry—the text that changed everything
Robinson's reply when his roommate asked if he was Kirk's shooter, according to court documents.

In the weeks following the September shooting of conservative activist Charlie Kirk on a Utah university campus, the legal machinery surrounding accused gunman Tyler Robinson has begun its slow, deliberate turn. A roommate's immunity deal, contested DNA evidence, and the shadow of the death penalty have transformed what began as a surveillance-footage identification into a complex courtroom reckoning. Two families now sit rows apart in the same chamber, each waiting for the law to render meaning from an act of violence that has already rendered so much loss.

  • Tyler Robinson, 23, faces aggravated murder charges and a potential death sentence after allegedly shooting Charlie Kirk on a Utah Valley University campus on September 10 — a crime he reportedly confessed to his roommate by text within hours.
  • The prosecution's forensic foundation is under immediate pressure: DNA on the towel wrapped around the suspected murder weapon matches roommate Lance Twiggs and likely Robinson, but defense attorneys argue the analyst cannot definitively place Robinson at the evidence.
  • Twiggs, granted use immunity for his recorded statements, sits at the center of the case's most tangled knot — his interviews were conducted twice, with prosecutors and FBI agents present, and last-minute defense redaction requests have complicated how his testimony will be heard.
  • Expert witnesses clashed over the reliability of DNA science itself, with the prosecution calling it 'the gold standard' while the defense raised the specter of transfer contamination — a dispute the court has deferred to trial.
  • Judge Tony Graf is expected to rule Friday on whether the case proceeds to trial, as both the Kirk and Robinson families attend each session, sitting only rows apart in a courtroom that has become a collision point for grief, justice, and legal strategy.

Tyler Robinson turned himself in on September 11, one day after Charlie Kirk was shot and killed on the Utah Valley University campus, after his father recognized him in surveillance footage and persuaded him to surrender. Now 23 and facing aggravated murder charges with the death penalty in play, Robinson had no prior criminal record — but investigators say he left a handwritten note under his keyboard declaring his intent to kill Kirk, and texted his roommate Lance Twiggs the same day to confirm he had done it.

At this week's preliminary hearing, prosecutors methodically presented their case. The suspected murder weapon — a bolt-action rifle with one spent casing — was found wrapped in a towel in a wooded area near the shooting. DNA on that towel matched two people: Twiggs and, according to FBI forensic analyst Amanda Bakker, very likely Robinson. Defense attorney Michael Burt challenged that conclusion directly, arguing the analyst could not definitively link his client to the samples. A prosecution expert from Cedar Crest College defended DNA testing as the most reliable tool in forensic science, while conceding it could be contested — for instance, through arguments about indirect transfer. The court declined to resolve the dispute at this stage, leaving it for trial.

Twiggs himself became a complicating figure. Granted use immunity in exchange for his recorded statements, he was interviewed twice by investigators — once in September with FBI agents, and again in April with a larger group of law enforcement and prosecutors present. Defense attorneys submitted last-minute redaction requests to the video recordings, prompting pushback from prosecutors who argued the changes were too complex and too late. An edited audio version of the interviews was expected to be played in court once both sides agreed on what to remove.

Through it all, two families have occupied the same courtroom. Charlie Kirk's parents, Robert and Kathryn, attended every session, occasionally stepping out when testimony grew too graphic. Tyler Robinson's parents, Matt and Amber, sat just rows away. Judge Tony Graf is expected to rule Friday on whether the case moves to trial — an outcome legal observers consider likely. Robinson has not yet entered a plea, and his attorneys' bid to remove the death penalty from consideration has already failed.

Tyler Robinson sat in a holding room at the Washington County Sheriff's Office on September 12, wearing a burgundy T-shirt, jeans, Converse shoes, and a black cap. Less than 48 hours had passed since Charlie Kirk, a conservative activist, was shot and killed on the Utah Valley University campus. Robinson had turned himself in the day before, after his father recognized him in surveillance footage from the shooting and convinced him to surrender. Now, as prosecutors built their case for an aggravated murder charge—one they intended to pursue with the death penalty—the machinery of the legal system was grinding forward.

At a preliminary hearing this week, the state laid out its evidence methodically. Robinson, 23, had no prior criminal record, but according to court documents, he had left a note under his computer keyboard that read: "I had the opportunity to take out Charlie Kirk and I'm going to take it." When his roommate, Lance Twiggs, asked him via text message on the day of the shooting if he was Kirk's killer, Robinson replied: "I am, I'm sorry." The two shared an apartment in St. George, a city in southwestern Utah. Investigators found the suspected murder weapon—a bolt-action rifle with one spent round—wrapped in a towel in a wooded area near where Kirk fell.

But the prosecution's case rested heavily on forensic evidence, and that foundation was already under attack. DNA on the towel matched two people: Twiggs and, according to FBI analyst Amanda Bakker, very likely Robinson. The defense seized on this uncertainty. Michael Burt, Robinson's lawyer, argued that the analyst "can't match Mr. Robinson to the questioned samples." A forensics expert called by prosecutors, Lawrence Quarino from Cedar Crest College in Pennsylvania, testified that DNA testing was "the gold standard" of forensic science and that law enforcement agencies used "extremely reliable" methods. But Quarino also acknowledged that DNA evidence could be challenged—a defense attorney might argue, for instance, that DNA material was transferred to a location through an intermediary. The prosecution countered that the reliability question would be settled at trial, not at this preliminary stage.

Another complication emerged from the prosecution's own witness list. Lance Twiggs, Robinson's roommate, had been given "use immunity" in exchange for providing recorded video statements to investigators. State Bureau of Investigation Agent Brian Davis explained that this meant prosecutors had agreed not to use Twiggs' statements against him in a criminal case. Twiggs had been interviewed twice—once on September 12 with two FBI agents present, and again on April 20 with Davis and several other law enforcement officers and prosecutors in the room. The defense team had proposed multiple redactions to the video at the last minute, but Deputy Utah County Attorney Lauren Hunt argued that redacting video was complicated and that the defense should have requested changes sooner. An edited audio version of Twiggs' interviews was expected to be played in court after both sides agreed on what would be removed.

The courtroom itself had become a stage for two families in collision. Robert and Kathryn Kirk, Charlie's parents, had attended every day of the preliminary hearing, though they sometimes left to avoid hearing details of their son's death. Tyler Robinson's parents, Matt and Amber, sat a row or two away, also present for each session. Judge Tony Graf was expected to rule on Friday whether the case should proceed to trial—a determination that legal experts said was likely to go forward. Robinson had not yet entered a plea. His attorneys had sought unsuccessfully to remove the death penalty from the table. The question of whether DNA evidence would hold up under scrutiny remained unresolved, a technical matter that would shape everything that followed.

Why does the roommate's immunity deal matter here? Isn't he just a witness?

Model

He's more than that. He's the person who found the note, who received the confession text, who lived with Robinson. His testimony could be crucial—but now the defense can't cross-examine him directly because he's not in the courtroom. They only get the video.

Inventor

So the prosecution is protecting him?

Model

In a way. They're saying he cooperated, so they won't use his own statements against him. But it also means the defense has to fight with what they can see on tape, not what they can ask him in real time.

Inventor

What about the DNA? Is it actually solid?

Model

That's the real fight. The DNA on the towel and rifle matched two people—the roommate and probably Robinson. But "probably" is the word that matters. The defense is saying the analyst can't definitively say it's Robinson. The prosecution says that's a trial question, not a preliminary hearing question.

Inventor

So they're kicking the hard questions down the road?

Model

Exactly. The prosecution wants the judge to say there's enough evidence to go to trial. The defense wants to stop it here. The judge will likely let it proceed, and then the real fight over DNA reliability happens in front of a jury.

Inventor

What does Robinson's silence mean?

Model

He hasn't entered a plea. His lawyers aren't saying he's innocent or guilty. They're just trying to keep him alive—literally. They've asked to remove the death penalty and lost. So they're fighting on the evidence now, hoping something breaks.
