Tyler Robinson, 22, just arrested. He's the one accused of killing Charlie Kirk during the prove me wrong event at Utah Valley University. He allegedly drove onto campus that morning in a great Dodge Challenger. Then, investigators say he changed clothes on the roof, shot from a building about 200 yd away, then slipped into the woods, leaving that rifle and bullet shells behind. Robinson was a third-year electrical apprenticeship student, had no major criminal history, but politicians and law enforcement say his political interest had grown strong lately, and not always passive. Family members told authorities he had spoken about Kirk's viewpoints and even disliked them. Here's the twist. His dad saw photos of the suspect, recognized him, pushed him to surrender. A family friend helped pass on information and in less than 36 hours after the killing, Robinson was arrested.
