15-Year-Old Girl Identified as the Shooter in a Wisconsin School

The shooter who killed at least two people on Monday at a Christian school in Madison, Wis., was identified as Natalie Rupnow, a 15-year-old student who later died from what appeared to be a self-inflicted gunshot wound, the police said.

The shooter, who went by “Samantha,” opened fire in a study hall classroom with students from several grades at Abundant Life Christian School, said Shon F. Barnes, the Madison police chief.

Officers arrived after a second-grade student placed a 911 call to report the shooting.

A teacher and a teenage student were killed, and five students and another teacher were injured, the authorities said. The shooter was found with a gunshot wound inside the school when police officers arrived and was pronounced dead soon after.
