Students from the school were stunned by the incident.

“I wish we could have done more to get support for the student, whatever he needed in life. Maybe it wouldn’t have happened, it would have been a different situation,” said student Adam Cyr.

One student said the school is a small community, which makes the classmate’s death so difficult.

“It makes me feel guilty to be honest, knowing I probably could have been that support he needed,” said student Hunter Levesque.
