Natalie “Samantha” Rupnow arrived at Abundant Life Christian School on Monday morning — and just hours later, she opened fire on a classroom, killing two and wounding six others, before turning the gun on herself.

Police identified 15-year-old Rupnow as the shooter at the private school in Madison, Wisconsin, and claimed the attack was premeditated.

A law enforcement source told CNN that Rupnow “have grappled with issues and expressed some of them in writings which they are now reviewing.” A manifesto was posted on social media that police have not confirmed is linked to the teenager.

The gunman, known as Samantha, was present from the start of the school day and eventually opened fire on a room full of students in various grades, according to Madison Police Chief Shon Barnes.

Police confirmed that the shooter, Rupnow, was not on their radar and had no interaction with her to date, although they said an investigation would confirm this.

It was not immediately clear to Barnes or investigators what grade Rupnow attended at the school, which serves students from the age of three through the end of high school.

When authorities arrived, Rupnow was found injured from a self-inflicted gunshot following the rampage and was pronounced dead en route to a local hospital.

Barnes said a second-grader called 911 at the school.

It has not yet been confirmed whether Rupnow’s family, which is cooperating with the investigation, was a gun owner.

Police searched her home on Delaware Boulevard Monday evening and found anything she may have left behind. A door appeared to have been torn down and left on the floor, and CNN reported that officers threw stun grenades into the home.

Barnes said they are currently speaking with the shooter’s father at one of their facilities and that he is cooperating.

“The parents are cooperating fully. We have no reason to believe at this point that they have committed a crime,” Barnes said, before expressing her condolences for her father.

“He also lost someone. “So we’re not going to rush the information, we’re going to take our time and definitely do our due diligence.”

The chief added that he had no knowledge of previous interactions with Rupnow: “I think if there were, we certainly would have had some sort of intervention, but I’m not aware of that.”

Police said they were aware of a manifesto allegedly written by the 15-year-old shooter that was circulating on social media.

However, police said they were unable to verify its authenticity.

Chief Barnes said at Monday night’s press conference, “A document regarding this shooting is currently circulating on social media, but we have not verified its authenticity.”

“We have not been able to verify that it is authentic.” “We are certainly aware that it was posted and that the person who posted it supposedly has a connection to the victim,” Barnes said.

The chief also engaged in online speculation about the shooter’s gender or his possible status as a transgender person.

Barnes criticized speculation about Rupnow’s gender on social media after being asked about it.

“I don’t know if Natalie was transgender or not. And honestly, I don’t think it matters at all,” he said.

“I don’t think what happened today has anything to do with how he or she wants to identify.” He added that it doesn’t matter much for now and that it “just doesn’t help.”

“For what we’re doing today, literally eight hours after a mass shooting at a school in Madison, at this point it doesn’t matter (what gender the shooter was),” he said.

He also claimed he had no knowledge of previous interactions with Rupnow: “I think if there were, we certainly would have had some sort of intervention, but I’m not aware of that.”

Police received a 911 call at 10:57 a.m. Monday morning, and within three minutes, county sheriff’s deputies had arrived at Abundant Life Christian School, which serves about 420 students. Seconds later, local police arrived.

At 11:05 a.m. they said they found the shooter wounded and recovered the weapon. Rupnow was pronounced dead on the way to the hospital.

At the same time, firefighters arrived on the scene and began tending to the victims. Two students are currently in hospital with life-threatening injuries and are said to be in critical condition.

A teacher and three other students were also hospitalized with less serious injuries. Two of them were released on Monday evening.

The victims have yet to be identified and family members have yet to be notified.

Gov. Tony Evers said on X: “I am closely following the incident at Abundant Life Christian School in Madison.”

“We are praying for the children, educators and entire Abundant Life school community as we wait for more information and are grateful for the first responders who are responding quickly.”

Wisconsin Senator Ron Johnson said on

The school was just days away from closing for the Christmas break and students were preparing for Monday night’s basketball game.

After the shooting, Abundant Life Christian School posted a prayer request on Facebook.

“There was an active shooter incident at ALCS today. We are in the middle of tracking. “We will share information as widely as possible,” the school said.

President Joe Biden was briefed on the school shooting. Senior White House officials said they were in touch with local counterparts in Madison to provide support.
