The police and school staff worked throughout the night to investigate this social media threat. While we made great progress in resolving the issue, there is still additional investigation that needs to be completed prior to students returning to school. Out of abundunce of caution and to allow police to comlete their investigation, we are cancelling school for today. Please know the safety of our students is our first priority.
