Jordan Brann, who went to Pine View High School in St. George, Utah, posted a TikTok that has since been deleted in which he said he knew the suspect, Tyler Robinson, from school.

Brann said, “Tyler Robinson and I went to school together.” “I can best describe him as a kid who uses Reddit. You know those kinds of kids from high school? That’s exactly what he was.

Brann made it clear in a second video that he wasn’t friends with Robinson, but he did see him a lot over the course of three years. It looked like he was the kind of kid who spent a lot of time online. I made the video because I wanted to show how people act when they spend too much time online.

Brann said in his posts that the suspect’s heavy internet use could have influenced his beliefs. “This is what happens when you spend too much time online and all of a sudden your beliefs are all the way this way or all the way that way, and you do some crazy things to make people who aren’t your friends happy,” he said.
