Of course, you had to turn the yearbook cover upside-down and look carefully. Most likely, I'd guess it was found by a student, rather than a school employee with too much time on their hands.
Shaker Heights High School Principal Michael Griffith wrote in a letter to students and parents that the cover of the yearbook, which featured a gathering of the school's Red Raider mascots, also contained the above "farewell message." In the letter, the offending student apologized, as well.
Cosmetic surgery is being done on the covers to remove the message. One has to wonder if the student or his parents are being billed for this; considering the budget issues of schools today, they should be.
