Superintendent Bill Crandall said that the principal, Mr. Belcastro, heard a rumor about a threat early Thursday morning. Belcastro informed Crandall, and based on what they knew, decided to close the school for the day.

The district, along with the Lake County Sheriff's office, conducted an investigation. There was no credible threat, according to Crandall. There was never any gun on school property or in possession of a student. No arrests were made, which was part of the rumor, Crandall added.
