Overview

• Authorities say the 22-year-old was arrested Thursday night, is held without bail, and is expected to face formal aggravated or capital murder and related charges early next week.
• Investigators tracked the shooter’s route via surveillance and doorbell video, concluding a single rooftop shot was fired before the suspect fled into a nearby wooded area.
• A Mauser bolt-action rifle believed to be the weapon was recovered wrapped in a towel, along with footwear and print impressions that remain under forensic testing.
• Officials reported bullet casings with taunting and anti-fascist or meme inscriptions, and say a roommate provided Discord messages discussing engraved ammunition, a scope, and a rifle “drop point.”
• Multiple outlets report a transgender-identifying partner or roommate is cooperating with investigators, a detail not publicly confirmed by law enforcement; a memorial event is set for Sept. 21 in Glendale, Arizona.
