Lake Station school district Superintendant Dan DeHaven said the 28-year-old Edison Junior-Senior High School business teacher, whose name was not released, was removed from campus Friday after putting a message on his chalkboard saying "the guns are loaded," WBBM-TV, Chicago, reported Tuesday.
The message, which was photographed by a student and posted to Facebook, read:
"Period 6: (only)
"(a) You are idiots!!!
"(b) The guns are loaded!!!
"(c) Care to try me?????"
DeHaven said the message was a response to comments made by the substitute teacher who had been filling in for the instructor for the previous two days.
The superintendant said the teacher's future with the district will be determined pending the outcome of an investigation.
