Cox laid out the events that led to Robinson’s arrest. The governor said that on the evening of Sept. 11, a family member reached out to a family friend, who then contacted the Washington County Sheriff’s Office with information that Robinson had allegedly confessed or implied he committed the shooting at Utah Valley University.

That information was then relayed to the Utah County Sheriff’s Office, investigators on the scene of the incident, and the FBI, Cox said. Investigators reviewed video footage and identified Robinson arriving on Utah Valley University’s campus in a gray Dodge Challenger at around 8:29 a.m. local time Wednesday, the day of Kirk’s event at the school, according to the governor.

Robinson was wearing a plain maroon T-shirt, light-colored shorts, a black hat with a white logo and light-colored shoes, Cox said.

When investigators encountered Robinson early in the morning on Sept. 12, he was wearing clothing consistent with that outfit, according to the governor.

Cox said that investigators interviewed one of Robinson’s family members, who said he had become more political and that Robinson had mentioned Kirk was going to be at Utah Valley University. The unidentified family member said Robinson and another person discussed why they disliked Kirk, according to the governor.
