Spring semester was off to a pretty normal start at Rolling Meadows High School. The school, in a northwest suburb of Chicago, was gearing up for the goodbye rituals of every spring semester: senior prom, end-of-year exams and graduation.
Caitlyn Walsh, the school's music teacher, was looking forward to the big choir concert and the spring musical. "From the fine arts scene we have a lot of end-of-year activities that are very cherished," she says.
