Overview

• Utah Gov. Spencer Cox said 22-year-old Tyler Robinson has not confessed and is refusing to cooperate while those around him are assisting investigators.
• Robinson remains in custody under special watch pending a mental-health evaluation, with prosecutors expected to file aggravated murder and related charges on Tuesday.
• New door-camera video released Sunday appears to show the suspect’s gray Dodge Challenger and later a man matching Robinson’s description walking near the scene.
• A source told Fox News Digital that the FBI is examining left-wing groups in Utah for possible ties to the suspect, a development reported but not detailed by officials.
• Authorities cite thousands of public tips — more than 7,000 — and say Robinson was identified after his father recognized him, while records and interviews point to Discord messages and engraved casings referencing antifascist and meme culture.
