People on Witness Stand

:::caution Legal Disclaimer Appearing on this roster means a person reportedly testified, had a recorded/Rule 1102 statement played or admitted, or is the subject of an open question about who was on the roof — not an accusation of crime. Tyler Robinson is charged, not convicted. All persons are presumed innocent. Rosters come from press, pool reporting, and hearing transcripts, and may be incomplete. :::

This is the full table of contents for people tied to the witness stand in State of Utah v. Tyler Robinson — primarily the 07/06–07/10/2026 preliminary hearing. For non-sworn event interviews at UVU, see Witnesses (different evidentiary weight).

The Court and People Level 2 pages each carry a short "People on Witness Stand" list (top 19 + More Witnesses → this page).

A. Live sworn witnesses (preliminary hearing) — complete set of 7

Transcript + press audit (July 2026): exactly seven people took the live stand and were examined. No other FBI special agents took the live stand; Amanda Bakker is the only FBI live witness. Defense called three forensic experts (Bakker, Karner, Oliver). Prosecution called four Utah LE witnesses (Bagley, Hull, Faumuina, Davis).

#PersonConnection
10Tyler Robinson's mother (not named here)Interviewed the night of the surrender (per Davis); charging documents refer to her only as "Tyler Robinson's mother." This site does not attach that role to any named person, and she is not the Lori Robinson profiled on this site — a general contractor connected only by surname coincidence
11Matt RobinsonFather — interviewed; DNA references in lab testimony commentary
12Deirdre AmaroChief medical examiner — autopsy report foundation via Hull
13Nate BrooksbyWashington County Sheriff — surrender/public timeline context
14Unidentified badge-carrierWith Bagley on roof; name never obtained; not known to have testified

D. Did not testify

PersonNote
Tyler RobinsonDeclined to testify at prelim; charged, not convicted
Jaxson Thomas FoxTransport order process fact — not a hearing witness for the State's murder case; see informant-order page

E. Extended list — people repeatedly discussed as if they were stand witnesses

Citizen threads often conflate event witnesses and hearing witnesses. For completeness of navigation (not a claim they took the stand in July 2026):

Use Witnesses (event accounts) for the non-sworn set.

Open questions

  1. Will a certified complete witness list and full transcripts issue for every day?
  2. Who was the second badge-carrier on the roof with Bagley?
  3. Which additional experts will the State or defense call if the case is bound over after 09/01/2026?
