A conflict took place between a student and a staff member at Lincoln Middle School in Syracuse, as reported in a letter from Principal Allison Dupree. The letter notified parents of the incident involving a verbal altercation with the exchange of inappropriate language captured on video. The school’s security team is investigating, and disciplining those involved. The Syracuse City School District confirmed the letter’s authenticity but did not offer additional comments. A lockout at the school on Monday was triggered by threats made by the suspended student’s parent.
