Denver schools spokesman Scott Pribble said in a statement the district put the teacher on administrative leave and completed an investigation after students raised concerns in March 2025. “The safety, emotional well-being, and dignity of our students are the absolute highest priorities of DPS,” the statement said. Bethel School District said in a statement that the vials in a display at Graham-Kapowsin High School in June were not authorized by school administrators and were immediately removed and turned over to the Pierce County Sheriff’s Office. The Education Department tied the new investigations to National Parents’ Day on Sunday. Pierce County Sheriff’s Deputy Carly Cappetto said Bethel school administrators identified the student who brought the vials to campus.
