A Utah sheriff is detailing how the suspect in the Charlie Kirk shooting ended up turning himself in.

Washington County Sheriff Nate Brooksby said Wednesday during a news conference that he got a call from a retired county detective around 8 p.m. on Sept. 11.

“I couldn't fathom what actually came out of his mouth: I know who Charlie Kirk's shooter is,” the sheriff said, quoting the former officer.

Brooksby said the friend traveled by car to the sheriff's office with Robinson and Robinson's parents for a peaceful surrender.

Robinson "was truly fearful of being shot by law enforcement,” Brooksby said in explaining why he agreed to have the alleged assassin transported to the sheriff's office instead of sending officers to arrest him.
