An 8th grade math teacher at a Sun Valley middle school was arrested this month after a suspected drug overdose on campus. According to an arrest report, 42-year-old Aaron Kepler was arrested on Dec. 10 after he ‘presumably overdosed’ at the Desert Skies Middle School campus. At the hospital, Kepler told paramedics he had fentanyl in his possession. Kepler then handed a container containing a white powder over to police, who later confirmed the substance was fentanyl. Keplers scheduled arraignment on Dec. 27.
