A Warren County School District student has been charged with having a weapon on school grounds on Tuesday.

The 18-year-old student, of Sugar Grove, is charged with possession of a weapon on school property and prohibited offensive weapons, both misdemeanors.

According to the affidavit of probable cause, a teacher at Warren County Career Center notified officials at Eisenhower High School that he suspected the student had made a knife in class and taken it with him when he returned to Eisenhower.

The principal questioned the student, according to the affidavit. He denied having made anything inappropriate at the career center, saying he had “made a fish” and denying that it was sharp. He also said it was not at the high school.

District officials searched the student’s locker, discovering a “rectangular piece of metal with a knife tip drawn on it,” and recommended that he be searched, according to the affidavit.

Using a metal-detecting wand, the principal checked the student, then moved to his coat, which he had removed, according to the affidavit. The student denied that there was anything inappropriate in the coat and that there was nothing sharp that might poke the principal during the search.

The principal “recovered a ‘dagger’ with an approximate 3.5-inch blade in his coat pocket that (the student) stated he created earlier that day at the WCCC,” according to the affidavit.

The student is scheduled to appear before District Judge Laura Bauer at 9 a.m. Wednesday for a preliminary arraignment.
