“Their presence has been incredibly helpful in managing safety priorities. We also thank our school safety team, administrators, and other staff for their quick response.

“This type of student altercation is not what we expect to occur within our schools, but you should know that we do take great measures to prepare for these types of incidents in these unprecedented times.

“There are many rumors and reports of what occurred that have been misleading. The high school was not locked down at any point yesterday. The student who sustained the laceration was released to his family.

“After consulting the school nurse, the family took the injured students for additional medical treatment.

“We continue to work closely with our local law enforcement agencies to thoroughly investigate what occurred and are committed to taking all necessary steps to ensure that our schools remain safe environments for learning.

“Finally, we ask for the cooperation and support of our students, staff, and community members as we navigate this challenging time together.”
