“The family member referenced a recent incident in which Robinson came to dinner prior to Sept. 10,” Cox said. “In that conversation, Robinson mentioned Charlie Kirk was coming to UVU. They talked about why they didn’t like him and the viewpoints that he had.”

Investigators also spoke with Robinson’s roommate.

“Investigators interviewed that roommate who stated that his roommate, referring to Robinson, made a joke on Discord,” Cox explained. “The content of these messages included… a need to retrieve a rifle from a drop point… messages related to visually watching the area where a rifle was left… engraving bullets… and a message referring to having left the rifle wrapped in a towel.”
