Who Testified — Hearing Witnesses
:::caution Legal Disclaimer Appearing on this roster means a person reportedly testified or was reported to be expected to testify. It is not an accusation. No one listed here is alleged by this site to have committed a crime, lied under oath, or acted improperly. Tyler Robinson is charged, not convicted, and every person named is presumed innocent. Rosters are assembled from press coverage and citizen-investigator clips, not certified transcripts, and may be incomplete or wrong. :::
Two very different groups of people are called "witnesses" in this case, and conflating them is the most common error in public commentary:
- Hearing witnesses — people who took the stand under oath in State v. Robinson, subject to cross-examination and perjury exposure. That is this page.
- Event witnesses — people who gave interviews about what they saw at UVU on September 10, 2025. Those accounts are not sworn and live in the Witnesses section.
An on-camera interview and sworn testimony carry completely different evidentiary weight. This page covers only the first kind.
The Roster (Reported)
| Witness | Role | What their testimony reportedly addressed |
|---|---|---|
| Chris Bagley | Former UVU campus police officer | First reported to reach the Losee Center roof (~12:44 p.m.); found the red-and-black screwdriver and disturbed gravel; body cam reportedly stopped recording on arrival |
| Agent David Hull | Federal agent | Chain of custody and the rooftop search; reportedly cross-examined by Kathryn Nester |
| Forensic / DNA analysts | State forensic witnesses | DNA links to Tyler Robinson; mixture profiles heavily featuring Lance Twiggs on the towel and screwdriver |
| Lance Twiggs | Cooperating witness | Reportedly cooperated and received limited immunity; not charged as the shooter |
| Unidentified badge-carrier | Unknown | Reportedly on the roof with Bagley; name reportedly never obtained; not known to have testified — an open question, not an allegation |
The Most-Argued Witness
Chris Bagley draws the most scrutiny for a structural reason rather than anything he is accused of: he is the person who reportedly found the key physical evidence, and his body-worn camera reportedly stopped recording as he reached the roof — so the discovery exists in testimony only, with no video.
On her podcast, Candace Owens stated that other police officers contacted her program saying the sudden blackout is highly implausible. Those officers are unnamed and not sworn, and their claim has not been tested in court. Body cameras do fail; the device logs would answer this far better than anonymous opinion. Bagley is a witness, not a suspect, and has never been charged with anything.
The Cooperating-Witness Question
Lance Twiggs reportedly cooperated and received limited immunity. Commentators treat immunity as inherently suspicious. It is not — immunity is a routine prosecutorial tool used in a large share of criminal cases, and it exists precisely so witnesses can testify without self-incrimination. That DNA mixtures feature Twiggs on shared items is likewise ordinary for a person who lived with the accused. Nothing here alleges Twiggs committed any crime; he is not charged as the shooter, and speculation to the contrary is unproven.
Separately, a reported transport order for Jaxson Thomas Fox — an unrelated inmate — is documented as a process fact that some commentators frame as informant positioning. See Jaxson Fox — Informant Order. We make no claim that Fox or anyone else did anything wrong.
Open Questions
- Who was the second badge-carrier on the roof with Bagley, and did that person testify?
- Where are the body-cam device logs that would independently address the battery account?
- Does a non-activation report under Utah Code § 77-7a-104 exist for that day?
- Which witnesses expected at the preliminary hearing were not called, and why?
- Will certified transcripts be released, or does the public record stay limited to clips? See Gag Orders & Sealing.
