It's hard enough for the adult psyche to process: a teacher allegedly murdered by a 14-year-old student. The Danvers school district brought in grief counselors to help students cope with the loss of 24-year-old math teacher Colleen Ritzer. The same was done in Newton earlier this month after two students committed suicide less than two weeks apart.

How can school systems help students process traumatic events like these recent tragedies? Larry Berkowitz, the director of the Riverside Trauma Center, is often one of the grief counselors brought into these schools to talk with students. Forensic psychologist Robert Mendoza also joined Greater Boston to talk about trying to understand what drives people to commit such horrible acts.
