"It is a tragedy for us," school Vice President Shawna Vercher told CNN. "Our hearts are with the families involved, and we are going to make sure our priorities are with those families.

"We will offer our support to help them get through this crisis," she said, noting that the facility has a screening process to keep weapons out of the school.

AMIkids operates 56 facilities across the nation and works with local school districts to educate students who have been expelled or suspended from schools elsewhere, school officials told CNN.
