After Nex Benedict died in February, the U.S. Department of Education found repeated violations of federal anti-harassment policies at Owasso schools.

In an agreement with federal investigators, Owasso school officials promised to address instances of discrimination and sex-based harassment of students.

The Oklahoma school district where a transgender student died earlier this year following an altercation in a school bathroom violated federal law by mishandling sexual harassment allegations, according to an Education Department investigation.
