Sexual abuse allegations
In 2023, Sumner High School and its school district faced a lawsuit from a group of six students who had claimed they had been sexually abused by a teacher at the school. The lawsuit claims that the school district was aware of the sexual abuse, but did not take action until it was reported by news outlets. In April 2023, Sumner High School basketball coach Jacob Jackson was charged with child rape and molestation, and subsequently fired from his position; two lawsuits were filed against him prior to the firing. Allegations of abuse were made against Jackson as early as 2018.
