Madison, Wisconsin - A school shooting in Madison, Wisconsin, has reportedly resulted in "several casualties" on Monday.

The shooting occurred at Abundant Life Christian, a K-12 school with nearly 400 studies, per CNN.

Madison Police Chief Shon Barnes told the outlet that there were "several casualties," and multiple victims have been transported to the hospital.

One suspect is "down," but searches are still ongoing.

"Yet another police chief is doing a press conference to speak about violence in our community, specifically in one of the places that's most sacred to me as someone who loves education and to someone who has children that are in schools," Barnes said during a press conference.

The state's governor, Tony Ever, addressed the tragedy in a post on X.

"I am closely monitoring the incident at Abundant Life Christian School in Madison," he wrote.

"We are praying for the kids, educators, and entire Abundant Life school community as we await more information and are grateful for the first responders who are working quickly to respond."

Police have announced a teacher and a student were killed in the shooting, with at least six reported injured, per CNN. Two of the wounded include students who are in "critical condition," while the other four have non-life-threatening injuries.

Madison Mayor Satya Rhodes-Conway condemned the US epidemic of gun violence, telling reporters, "I am on record that I think we need to do better in our country and our community to prevent gun violence. And I hoped that this day would never come in Madison.

"It is not something that any mayor, any fire chief, any police chief, any person in public office ever wants to have to deal with."

Law enforcement also revealed that the shooting was "confined to one space," but it's unclear whether this was a specific classroom or a hallway.

Madison police have corrected the death toll of Monday's shooting to at least two victims, with the suspect also dead, per AFP.

Seven people were transported to the hospital with injuries ranging from minor to life-threatening.

Chief Barnes added that it is an "ever-evolving situation" and asked for patience as they continue the investigation.

Police have now confirmed that at least four were killed and another five have been injured in Monday's shooting, per CBS News. The suspect, reportedly a juvenile who attended the school, is also dead.

Officers have declined to identify the victims, with Barnes adding, "I'm not going to give any information about who the victims are, whether they're students, staff or parents, because we need to make sure that we can notify people."

Emilie Simons, the White House's senior deputy press secretary, confirmed that President Biden has been briefed on the shooting.
