Christian school shooting leaves teen student, teacher dead

A teacher and teenage student were killed and six others hurt in a shooting at Abundant Life Christian School in Madison, Wisconsin, on Monday, police said.

Police had briefly mentioned a higher death toll but later revised the information.

The suspect, a student at the school, is also dead, police said.

The teen suspect was female, multiple law enforcement sources told ABC News.

A motive is not clear, Madison Police Chief Shon Barnes said at a news conference.

The teenage suspect used a handgun, police said. Authorities are investigating the origin of the firearm, Barnes said.

Two students are in critical condition with life-threatening injuries, Barnes said. Three other students and a teacher suffered non-life-threatening injuries, he said Monday evening. He had previously said six students were injured before including a teacher among the victims.

Officers responded to the active shooter report around 10:57 a.m. The suspect was dead upon police arrival and no officers fired their weapons, Barnes said.

The shooting was "confined to one space," but it's not clear if it was a classroom or hallway, the chief said.

Police believe that the suspect was already in the school and that there wasn't any breach.

"I never saw so many police cars in my life -- just blue and red lights lining the school, lining the streets. Fire department, paramedics, everybody was there," swarming the usually quiet neighborhood, John Diaz De Leon told ABC News Live.

He said he saw officers with long guns at the scene and older students run from the school across the parking lot.

"Later on, very slowly in a more orderly fashion, the younger students holding hands were let out to go across the parking lot," he said.

The school has been cleared, Barnes said. There's no danger to the community, he said.

The suspect's family is cooperating, the police chief said.

Detectives are investigating whether there were any potential warning signs, Barnes said.

All students had been reunited with their parents by Monday evening, Barnes said. About 390 students from kindergarten through 12th grade attend the private school.

Barbara Wiers, the director of elementary and school relations for Abundant Life Christian School, thanked first responders for their support and said the school community is leaning on their faith at this time.

"This has obviously rocked our school community, but we know it affects not just our school community, but Madison and the greater area and all schools," Wiers said at a press briefing on Monday. "Our hope is that there will be some good that comes out of this as we can learn and grow and continue to support other schools."

The school does not have metal detectors or a school resource officer, but has other security protocols in place, she said.

President Joe Biden called the incident "shocking and unconscionable" in a statement Monday evening that called on Congress to act, "now."

He insisted that they pass "commonsense" gun safety laws including universal background checks, a national red flag law and a ban on both assault weapons and high-capacity magazines.

"It is unacceptable that we are unable to protect our children from this scourge of gun violence," the statement said, adding, "We cannot continue to accept it as normal."

Biden also mentioned his administration's efforts to combat the gun violence epidemic in the United States, including the implementation of the White House Office of Gun Violence Prevention, while stating that more needed to be done and offering his prayers to those affected in Madison.

The Madison police chief said he began his career as a teacher.

"We owe it to our community to do everything possible to ensure [schools are] not only a special place, but a safe place," he said.

"I hoped that this day would never come in Madison," Madison Mayor Satya Rhodes-Conway said.

She stressed the need for gun violence prevention and said she wants the community and country to make sure "no public official ever has to stand in this position again."

Jill Underly, Wisconsin's superintendent of public instruction, also emphasized the need for change, saying in a statement, "This tragedy is a stark reminder that we must do more to protect our children and our educators to ensure that such horrors never happen again. We will not rest until we find solutions that make our schools safe."

Wisconsin Gov. Tony Evers said in a statement, "There are no words to describe the devastation and heartbreak we feel," calling the shooting a "gut-wrenching tragedy."

Evers said he and his wife are "praying for the families and loved ones of those whose lives were so senselessly taken and for the educators, staff, and the entire Abundant Life school community."

"It is unthinkable that a kid or an educator might wake up and go to school one morning and never come home," he said. "This should never happen, and I will never accept this as a foregone reality or stop working to change it."
