Counselors were at the school to talk to students about the attack. Schlomann said the school is asking for help from students and the community to see if other students have been assaulted.

“We want to know that. So does the Kane County State’s Attorney want to know that,” he said.

Schlomann said Lee has been suspended without pay, and Monday night the school board will vote on firing him.
