MADISON, Wis. (AP) 鈥� The motive for a and wounded others at a Wisconsin school appears to be a 鈥渃ombination of factors,鈥� a police chief said Tuesday as he appealed to the public to share what they might know about the 15-year-old girl who attacked a study hall before shooting herself.
Madison Police Chief Shon Barnes offered no details about a possible motive, though he said bullying at Abundant Life Christian School would be investigated.
Barnes said police are also investigating writings that may have been penned by Natalie Rupnow and could shed light on her actions.
鈥淚dentifying a motive is our top priority, but at this time it appears that the motive is a combination of factors,鈥� the chief told reporters.
Barnes gave the number to a tip line for anyone who might have known the shooter and her feelings.
鈥淭here are always signs of a school shooting before it occurred. We're looking into her online activity,鈥� he said.
In addition to the deaths, including two students who remain in critical condition. The shooter died of a self-inflicted gunshot.
Barnes made remarks at a news conference but left without taking questions from reporters, leaving the Madison mayor and Dane County executive to face the media. They declined to disclose the names of the victims.
鈥淟eave them alone,鈥� Mayor Satya Rhodes-Conway snapped.
Abundant Life is a nondenominational Christian school 鈥� prekindergarten through high school 鈥� with approximately 420 students in Madison, the state capital.
Mackenzie Truitt placed a red poinsettia plant at the school to honor the victims Tuesday. She said her brother is a graduate and some of his friends were wounded.
鈥淢y heart sunk because I know how awesome a lot of these kids are,鈥� Truitt said. 鈥淚 know how scared everybody was. Couldn鈥檛 get a hold of certain people. Just really scary having to deal with that.鈥�
Barbara Wiers, the school's director of elementary and school relations, said the school does not have metal detectors but uses cameras and other security measures.
Barnes said police were talking with the shooter鈥檚 father and other family members, who were cooperating, and searching the shooter's home.
The shooter's parents, who are divorced, jointly shared custody of their child, but the shooter primarily lived with her 42-year-old father, according to court documents.
Barnes said the first 911 call to report an active shooter came in shortly before 11 a.m. from a second grade teacher 鈥� not a second grade student as he reported publicly Monday.
First responders who were in training just 3 miles (about 5 kilometers) away dashed to the school for an actual emergency, Barnes said. They arrived three minutes after the initial call.
Investigators believe the shooter used a 9mm pistol, a law enforcement official told The Associated Press. The official spoke on the condition of anonymity because they were not authorized to discuss the ongoing investigation.
Carolyn Griese, 70, of Monona, didn鈥檛 have any affiliation with the school, but she felt moved to drive over Tuesday. She cried as she placed flowers on the sidewalk.
鈥淲hen I was growing up, we worried about the atomic bomb,鈥� she said. 鈥淎nd now they actually practice active shooter scenarios. And I think how could that be? They鈥檙e children. Innocent children.鈥�
Vice President Kamala Harris addressed the shooting during a speech to students in Maryland on Tuesday.
鈥淥ur nation mourns for those who were killed and we pray for the recovery of those who were injured,鈥� she said.
Harris also called for stronger gun control laws.
A crowd of several hundred people gathered Tuesday evening at the foot of the Vel Phillips statue outside the Wisconsin State Capitol, passing candles to each other and standing close against the winter chill.
Madison resident Cristian Cuahutepitzi said he attended the vigil to let the families of the victims know 鈥渨e're thinking of them.鈥� He said his uncle's two daughters go to the school.
鈥淭hey're still a little bit shook,鈥� he said.
Naomi Allen, 16, is a student at the school. She said she had been in a nearby classroom when the shooting happened.
鈥淢y best friend 鈥� if she hadn鈥檛 stayed home from school 鈥� she would have been in that room,鈥� she said.
Allen's father, Joe Allen, said the country needs to take mental health seriously.
鈥淲e really need some changes in the way we we handle that issue,鈥� he said.
Joe Gothard, the superintendent of the Madison Metropolitan School District, said at the vigil that the tragedy happened less than two blocks away from his childhood home. He said it wasn't enough to say the district would work on safety.
鈥淲e need to connect like we are tonight, each and every day and make a commitment that we know we鈥檙e there for one another, hopefully to avoid preventable tragedies like yesterday,鈥� he said.
The school shooting was among dozens across the U.S. in recent years, including especially deadly ones in ; ; and .
The shootings have set off fervent debates about gun control and frayed the nerves of parents whose children are growing up accustomed to doing active shooter drills in their classrooms. But school shootings have done little to move the needle on national gun laws.
School shootings by teenage females have been extremely rare in U.S. history, with males in their teens and 20s carrying out the majority of them, said David Riedman, founder of the K-12 School Shooting Database.
In a blog post last year, he mentioned a handful of school shootings that involved perpetrators who identified as female, including a 16-year-old girl who shot and killed two and injured several others at San Diego elementary school in 1979.
Firearms were the among children in 2020 and 2021, according to KFF, a nonprofit that researches health care issues.
