The most newsworthy moment in the Charlie Kirk case played out in a Provo courtroom this week: FBI and state lab experts told Judge Tony Graf that mixed male DNA found on a towel and a screwdriver appears to include profiles that match the accused shooter, Tyler Robinson, and his roommate and partner, Lance Twiggs. That testimony is the latest, and perhaps most direct, piece of physical evidence tying the two men to items prosecutors say were used in the rooftop killing.
What the DNA evidence actually shows
Prosecutors say a towel wrapped around a bolt‑action rifle and a screwdriver recovered on the rooftop where the shot was fired both contained mixed male DNA. FBI analyst Amanda Bakker told the court Robinson was a “possible contributor” to those samples. Lab specialists said the mixed samples could reflect two people once investigators compared them to a sample from Robinson’s roommate, Lance Twiggs. In plain language: DNA testing links both men to the objects, but the samples were mixed rather than pristine single‑source matches.
Defense: mixed, degraded, and not as solid as headlines
Defense lawyers hammered on the limits of the testing. They pointed out the samples were mixed and in places degraded, and they pressed lab witnesses on how much confidence those conditions allow. That line of attack is routine, but it matters. Mixed DNA can be harder to interpret. The jury stage — or in this case the judge deciding probable cause — will turn on how the court weighs those scientific limits against the raw fact of the matches.
Twiggs’ immunity and the higher legal stakes
Another sharp new development: prosecutors say they gave Lance Twiggs limited use‑immunity for a recorded statement he gave investigators, and they plan to play that recorded interview during the hearing. Twiggs has not been charged. The defense wants the chance to cross‑examine him in person. Meanwhile, prosecutors are pursuing aggravated murder charges and have put the possibility of the death penalty on the table. Judge Tony Graf must now decide whether there’s enough evidence to send this case to trial.
Why this matters — and what to watch next
This DNA testimony is the prosecution’s attempt to stitch surveillance, witness accounts and digital records into a single story: Robinson fired from a rooftop, hid a rifle in a towel, and fled. If the judge finds probable cause, the case moves to trial and the forensics fight goes public. If the court finds the DNA evidence too shaky when paired with defense challenges, the prosecution will have to rely more heavily on other proof. Either way, families and the public deserve a full, clear accounting — not courtroom theater or rushed conclusions. Expect the judge’s ruling to be the next headline everyone watches closely.
