Utah Department of Public Safety Commissioner Beau Mason on Thursday said the suspect “blended in well with the college institution.”
Two previous people of interest in connection with Kirk’s murder have been released.
Videos and images, reportedly of Robinson, began flooding the internet following the news.
A report in The New York Times said that the person arrested is in his 20s. The individual detained was taken into custody in St. George, Utah, which is about 250 miles form Orem, Utah, where Kirk was shot to death at Utah Valley University.
In a video posted to X, President Donald Trump said “Somebody who was very close to him turned him in.”
