The shooter was a student at the school and is now among the dead, police believe.
Madison police officers are still investigating and collecting evidence, but a juvenile found dead at the school is believed to be the gunman at Abundant Life Christian School this morning.
No officers fired weapons in their response to the shooting, Police Chief Barnes told reporters.
At least seven people were transported to area hospitals for treatment after officers administered “lifesaving efforts” to anyone they found wounded, Barnes said.
Barnes did not provide information on how many were students or staff. The police incident website said that the injuries “range from minor to life-threatening.
