“We’re all trying to get it through it together, student Casey Silva told WBZ-TV’s Jim Smith. “You don’t really know what’s happening so you don’t know what to do. It’s… sad for everybody.”

The four students were seriously injured when their car crashed head on with a school bus on Friday.

Police say the car was on its way to school when it crossed the yellow line and crashed into an empty school bus that had just dropped off a load of students.

The school district considered canceling the prom, but Superintendent John Tuffy says it was the right decision to gather students together under the same roof.

“(I) thought it’d be a good idea to have the students all together in a safe environment where there would be trusted adults they could talk to, and it turned out to be the right decision. The kids had a wonderful time. They also found comfort in being with each other,” he said.
