About 15-20 Auburn Middle School school students were treated for minor injuries Tuesday morning after a chain reaction crash involving three school buses. The buses were headed from Auburn to Syracuse for a performance of “To Kill A Mockingbird” at the Oncenter in Syracuse. There’s been no official word on the cause of the crash, but one student says a driver cut off the first bus in the group. A spokesperson at one hospital says the most serious injury was a bloody nose. Those with no apparent injuries were checked over at the Oncenter before being sent back to school.
