The man accused of fatally shooting conservative activist Charlie Kirk has been identified as Tyler Robinson, 22, a Utah native who had been living with his parents for a long time, authorities said.

Mr. Robinson was taken into custody on September 12 after a family member recognized him in surveillance images, a development investigators described as pivotal in ending a nationwide manhunt.

That family member was apparently Mr. Robinson's father, who encouraged him to turn himself in, as reported by CBS News. The father then reportedly reached out to a family friend who contacted the sheriff's office.

At a press briefing on Friday announcing the arrest, FBI officials declined to discuss Mr. Robinson's background, political leanings, or possible motive, stating the investigation is ongoing. We are confident we have the right individual in custody, an FBI spokesperson said, but we are still working to establish the full picture of who he is and why he acted.

Utah Governor Spencer Cox revealed that a family member interviewed by investigators stated that Mr. Robinson had become more political in recent years. The relative also mentioned a pre-attack dinner conversation where Mr. Robinson expressed his disdain for Kirk, claiming he was full of hate and spreading hate while discussing Kirk's upcoming event at Utah Valley University.

Public records suggest that Mr. Robinson had registered in the past as a nonpartisan voter in Utah, while his parents are registered Republicans. He was not enrolled at UVU, the site of the shooting, and had attended Utah State University for a single semester in 2021.

Investigators noted Mr. Robinson's deep engagement in online culture, highlighted by inscriptions on shell casings linked to the case. These included references to trolling humor, anti-fascist sentiments, and even lyrics from a partisan song honoring World War II resistance. His online activities extended to Discord, where messages were found regarding weapons logistics.

As he remains in custody, prosecutors are preparing formal charges while authorities continue investigating this politically charged case, deemed significant in US history.
