Suspect in fatal shooting of Charlie Kirk 'not cooperating' with authorities, says Utah Gov Cox

Utah GOP Gov. Spencer Cox said Sunday that the suspect in the fatal shooting last week of conservative political activist Charlie Kirk is not cooperating with authorities.

"He has not confessed to, to authorities," Cox told ABC News. "He is not cooperating, but, but all the people around him are cooperating."

Authorities have identified the shooter in Kirk's death Wednesday as 22-year-old Tyler Robinson, of western Utah. 

Robison is in custody after turning himself into authorities, reportedly as the urging, or demand, of his father. He expected to be formally filed on Tuesday, Cox said.
