Racist graffiti was again discovered at the Oak Park and River Forest High School for the second time in less than a week. School officials sent a note to parents Tuesday evening, informing them that another racist message was found at the campus. "We want to assure you that we take any incident of hate speech or hate crime on campus with the utmost seriousness. We immediately reported these incidents to the police and launched our own investigations. We have security cameras inside and outside the building and are reviewing hours of footage to try to identify the perpetrators," wrote Superintendent Dr. Joylynn Pruitt-Adams
