Three students have now confessed to making threats at Union Local Schools.
Superintendent Kirk Glasgow says all three suspects are students at the school.He says one is already suspended from school, and the other two will be.
He's not specifying the age or gender of the suspects. Their punishment will start with a ten-day suspension but could become a one-year expulsion.
Threatening notes were left on walls or found on paper in the elementary, middle and high schools five times over a period from last Monday through Wednesday.
