"While we don't know all of the details at this point, what we do know is that these incidents are rarely spontaneous and in fact have been developing over a long period of time, offering many opportunities to intervene in a mental health crisis situation. We know if we identify kids, get to them early, help them with medication and counseling, it can make a world of difference. But there is a severe shortage of outpatient and inpatient treatment options for these children, which is why we need to pass the Helping Families in Mental Health Crisis Act.
"Our hearts go out to the students of Franklin Regional High School and the families of the entire school district. They are in our prayers tonight."
