CORNING, Iowa — According to a report published in the Creston News Advertiser, a Principal for the Southwest Valley High School has resigned. Anthony Donahoo, who is also a football coach, will step down at the end of this year.

The news follows an incident of a threat of violence that was known two-weeks before school administrators and law enforcement were made aware of the alleged threat. The student in question is no longer allowed at the school.

Deputies with the Adam’s County Sheriff’s Office are providing extra security at the school for the rest of the year, as a precaution.
