The police chief investigating Monday’s deadly shooting at a Christian school in Wisconsin is adamant that the 15-year-old killer’s gender identity is “not important at all.”

Madison Police Chief Shon Barnes dismissed concerns about Natalie “Samantha” Rupnow’s identity when asked about early rumors that she may be transgender.

“I don’t know if Natalie was transgender or not. And honestly, I don’t think that matters at all,” Barnes said of Rupnow, who died of a self-inflicted gunshot wound after killing a teacher and a student.

“I don’t think what happened today has anything to do with how she or he or they want to identify,” he said.

The comments came as he was asked about a spate of unverified online posts claiming the 15-year-old was transgender, suggesting it played a role in the carnage at the K-12 Abundant Life Christian School .

“I wish people would give up their personal prejudices,” complained the police chief.

“We have lost members of our community. It’s something that may come to light later, but it has no relevance to what we do today at this point.”

Police said Rupnow, a student at the private Christian school, brought a handgun to campus around 11 a.m. and opened fire in a classroom during class.

When the gunfire erupted, a second-grader in a nearby classroom called 911 for help, and police were on the scene within about three minutes, according to Barnes.

The teenage student and teacher were pronounced dead at the scene, while another teacher and five other students were injured.

Two of the students were in critical condition and had life-threatening injuries, Barnes said Monday evening.
