The full picture is only beginning to emerge of Utah resident Tyler Robinson, who authorities arrested Friday for the assassination of conservative activist Charlie Kirk.

Gov. Spencer Cox said Mr. Robinson had “confessed” to a “family friend” who subsequently told the authorities. A law enforcement official told The Associated Press that his father recognized him from the images and encouraged him to turn himself in. He initially refused but then changed his mind.

Here’s what is known so far about the shooter:

• He was said to have become “more political” in recent years, Mr. Cox said the family said.

• He grew up in Washington, Utah.

• He is 22 years old.

• His parents are Amber and Matt, and he has two younger brothers, according to his mother’s Facebook.

• His family appeared close, according to photos of the sons and family trips posted to the mother’s Facebook, which has since been deleted.

• He briefly attended Utah State University for one semester in 2021, a statement posted to the school’s website says.

• Messages written on the cartridges that were found inside the gun referenced video gaming, LGBTQ and antifa, a left-wing, militant movement whose name is short for anti-fascist.

• Also engraved on the cartridges were arrows that referenced controller moves that unleashed bombs in a video game.

• Another phrase, “Notices bulges OwO what’s this?” is used for trolling online.

• Another engraving said “Bella ciao,” which is an Italian anti-fascism song.
