Overview

• Investigators report DNA matches to Robinson on a towel that wrapped the recovered rifle, tools found on a rooftop, and the weapon’s trigger, and say a destroyed handwritten memo was reconstructed.
• The Washington Post published messages in which the suspect allegedly wrote "I did it" and indicated he would surrender shortly before authorities announced his detention.
• Charging documents state a single rifle round was fired from a rooftop about 150 meters away during an outdoor event at Utah Valley University.
• Robinson surrendered at a sheriff’s office roughly 400 kilometers from the scene, then made an initial online court appearance, with the next hearing set for Sept. 29.
• The FBI is investigating participants in the suspect’s online communities, while President Trump publicly blames the "radical left" and says a large-scale inquiry has begun.
