The two schools are the last in District 155 to conduct the drill for students. Crystal Lake South held its drill before winter break, and Cary-Grove conducted its drill two weeks ago, which included two school officials shooting off blanks. The inclusion of the gunfire sounds drew media attention from throughout Chicagoland.
Letters to parents from Central and PR specifically state simulated gunfire will not be a part of the drill, the Herald reports. Cary-Grove's choice to include the gunfire sounds did not impact this decision, the story states. Crystal Lake Police officers will be present at both schools on Tuesday to help with the drills, expected to last about 15 minutes.
