SALT LAKE CITY (AP) – On June 22, 2026, Utah Judge Tony Graf ruled against a defense request to compel Tyler Robinson's former roommate and romantic partner to testify in person during the upcoming preliminary hearing. The judge stated that determining witness credibility is not within the scope of a preliminary hearing but will be addressed later if the case proceeds to trial.
Robinson, 23, faces aggravated murder charges for the September 10 shooting death of conservative activist Charlie Kirk at Utah Valley University. DNA evidence consistent with Robinson's was found on the trigger and casing of the rifle used in the crime, as well as two unfired cartridges. However, defense attorneys argue that multiple individuals' DNA were present on some items, necessitating further analysis.
The preliminary hearing is scheduled to begin July 6, where prosecutors aim to establish sufficient evidence for a trial. Robinson's legal team requested the roommate’s live testimony so they could challenge her credibility directly. Judge Graf denied this request, emphasizing that such challenges should be reserved for potential jury deliberations if the case moves forward.
Additionally, Judge Graf postponed ruling on whether prosecutors might face sanctions over media comments regarding a bullet fragment found in Kirk's body until June 30. Defense attorneys claim these statements could prejudice future jurors and have asked to block the death penalty from being sought by prosecutors due to this potential juror bias.
The case has garnered significant public attention, with online speculation fueling conspiracy theories about possible alternative shooters or staged events following inconclusive initial tests on ballistics evidence. Both sides are concerned that extensive media coverage could affect jury impartiality in a future trial setting.
