The alleged assassin of Charlie Kirk is refusing to cooperate with the authorities, despite those around him helping the FBI's investigation into the shooting.
Tyler Robinson, 22, was taken into custody on Friday after confessing to his father, Matt Robinson, that he was guilty of killing the 31-year-old conservative activist at Utah Valley University.
His father, who owns a construction company, contacted the authorities and secured his son after he allegedly told him that we would rather take his own life than surrender himself.
Utah Governor Spencer Cox told ABC News that the suspect had "not confessed to authorities", before adding that while "he is not cooperating, all people around him are cooperating".

"It’s fairly obvious this was an ideologically motivated attack.
"Charlie Kirk is a conservative commentator who sadly and tragically gave his life underneath a sign asking people to challenge his ideas, the very essence of our constitutional republic."
According to the Washington Post, the 22-year-old sent a message to a group on messaging platform Discord after the attack which read: "Hey guys, I have bad news for you all.
"It was me at UVU yesterday. I'm sorry for all of this."
