Authorities are investigating a school shooting in Madison, Wisconsin, where a 15-year-old student, Natalie Rupnow, also known as Samantha, shot and killed a teacher and a fellow student. The incident occurred in a study hall classroom at Abundant Life School. Police are exploring multiple factors that may have motivated the shooting, including Rupnow's apparent interest in neo-Nazi ideology and online forums that idolize mass shooters. Investigators are examining online accounts linked to Rupnow, which include posts made shortly before the shooting that suggest extremist influences. A vigil for the victims is planned, and the community is in mourning as authorities continue to gather evidence and understand how Rupnow obtained the handgun used in the attack.
