You've probably heard the troubling news in our community. A third-grade teacher at Arrowhead Elementary School recently was arrested and charged with sex crimes involving students in his classroom.

The teacher, who we immediately placed on suspension pending termination proceedings, was popular with students and parents alike. He had passed multiple background checks and came to us with strong employment recommendations.

Despite all these reassurances, this teacher betrayed the trust of his students, their parents and all of us who've dedicated our lives to educating and protecting children. In his wake, countless families -- those directly and indirectly victimized -- are left to pick up the pieces.

This teacher now faces felony charges that could possibly lead to a life sentence in prison. As his case moves through the justice system, the Olentangy Local School District family will move forward to foster an atmosphere of healing and a continued commitment to protecting children.

As the superintendent of this district, it's my top priority to make sure this happens.

Just this week, Delaware County Sheriff Russ Martin met with school leaders and pledged to work closely with us to make sure our students are able to learn in a safe environment.

We were pleased when he released a video statement to the community in which he said, "Day in and day out, thousands of our students are safely entering the halls of our schools and being taught by the most competent teachers and staff available."

We're proud that Sheriff Martin recognizes how safe our schools are. In fact, we have nearly two dozen safeguards in place to protect the children we're entrusted to teach.

But since this teacher was able to commit his act of betrayal while so many safeguards were in place, we're going to work with subject-matter experts and community leaders to review best practices nationally to see what other steps can be taken to keep our children safe. It's the right thing to do.

We stand side by side with Sheriff Martin in a joint effort to unite this community in a spirit of support and caring for the families affected by this tragedy.

As soon as we learned of this situation, we pledged our full cooperation with law enforcement and prosecutors to see that justice is done.

We've also made extra counselors available in school, in case any student may need additional support and help.

We understand that many parents and taxpayers will have questions about how a crime such as this can happen in a school setting.

We know similar incidents have happened in schools across the country and throughout Ohio, but our aim is for Olentangy to be better than that. We know our parents expect -- and deserve -- the best.

School board President Kevin O'Brien also released a public statement.

Kevin is a parent of four daughters in our school system and he brings the heart of a father to the work he does in our schools. He knows -- as I do -- that our district's response must be sincere, credible and transparent.

One of the statements Kevin made while appearing with Sheriff Martin is particularly appropriate to our district's response.

He said: "We all know that the measure of an organization is not whether it faces adversity or problems. The true measure is how that organization deals with those problems. We will act quickly and thoroughly so that we can continue to earn the confidence of parents and the Olentangy community."

That's as good a statement of the Olentangy mission as I've heard. And it's my commitment to this community to help our school leadership live up to it.
