On Wednesday, Feb. 14, a 19-year-old gunman killed at least 17 people at Marjory Stoneman Douglas High School in Parkland, Fla. Later that day, Wilton Superintendent Kevin Smith addressed the school shooting in the following letter to parents, guardians and caregivers:

“Our thoughts and prayers are with the families of Parkland, Florida. As adult caregivers our hearts break for those devastated by this senseless act.

We must also step back and consider the mental health crisis gripping our young across this nation. There is much to explore and much to do to ensure our children grow to be healthy and resilient. Please know that our schools are committed to this effort and committed to ensuring that our children are safe.

Tomorrow, as one additional step to provide some measure of comfort, you can expect to see a more visible police presence on our school campuses. Our teachers will be on alert for any students who may be feeling particularly anxious and our mental health providers will be available to speak with any student who requires their support. If you are concerned about your child please contact your school’s administrators or school counseling staff.”

On its Facebook page, the Wilton Police Department expressed on its “deepest condolences” to those affected by the tragic event and said the department “recognizes the concern this may cause for parents and children in our Wilton schools.”

The department asked people to “not be alarmed” by its “visible presence” around Wilton schools on Thursday, Feb. 15. “It is just a reminder that we are here to keep the children and staff in our schools as safe as possible,” the department wrote.
