A four-and-a-half million dollar school bond issue was defeated Tuesday by voters in southwest Iowa’s A-H-S-T district. The measure got 52-percent approval but needed 60-percent to pass. It passed with more than 60-percent in Avoca and Hancock but failed miserably in Shelby. Had it been approved, the bonds would have been used to build a new pre-K-through-sixth grade onto the south end of the existing A-H-S-T high school building.
