Madison Police Chief Shon Barnes identified the shooter as Natalie Rupnow, 15, who went by Samantha and attended Abundant Life Christian School. "I put my head in my hands and started to cry. We had never gotten too in-depth about the religions of our families — and now I see we should have."

Researchers at the Anti-Defamation League identified a TikTok account belonging to the Madison school shooter that posted racist and violent content.
