Shooter at Abundant Life Christian School in Wisconsin ID’d as 15-year-old Natalie ‘Samantha’ Rupnow

Authorities have identified the teen girl who shot dead a student and teacher and left two more pupils clinging to life at a private Christian school in Madison, Wis., on Monday.

Police said Natalie “Samantha” Rupnow, a 15-year-old student at the K-12 Abundant Life Christian School, brought a handgun to campus and opened fire around 11 a.m., Madison Police Chief Shon Barnes said Monday night. The shooter was later found dead at the scene from a self-inflicted gunshot wound, sources told CNN.

A teenage student and a teacher were killed, while six more people were wounded, including two teens critically, officials said.

The school, which is in the state capital, has about 400 students.

Bethany Highman, whose daughter attends the school, described her terror before she FaceTimed with her child and learned she was safe.

“As soon as it happened, your world stops for a minute. Nothing else matters,’’ Highman said. “There’s nobody around you.

“You just bolt for the door and try to do everything you can as a parent to be with your kids.”

The school wrote on its Facebook page, “Prayers Requested! Today, we had an active shooter incident at ALCS.

“We are in the midst of following up. We will share information as we are able.”
