A former Utah Valley University police officer described the chaotic scene after conservative activist Charlie Kirk was assassinated on the school’s campus last year during a key preliminary hearing ahead of the murder trial over Kirk’s death.

Chris Bagley, a former UVU police officer who worked during the event where Kirk was killed, was the first witness called by state prosecutors to testify at the weeklong hearing to determine if there is probable cause for Tyler Robinson to go on trial for murder charges for the alleged killing of Kirk. Bagley said he saw Kirk slump over to his left after hearing a gunshot fired, with people in the crowd around the activist getting up and running in what he described as a “chaos kind of situation.”
