In launching his We Isolate No-one initiative - or WIN - Zachary Cruz says he'll spend the summer creating student-run chapters in schools nationwide.
He says, "it will train to spot bullying, abuse and isolation and how to intervene to head off a problem."
His 24-hour anti-bullying hotline will be staffed by counselors, the information will be shared with the school principal and with the support of a civil rights law firm, WIN will investigate the claims further.
Cruz stresses, "I can not stand here today and defend my brother or make excuses for him. However, I can say very clearly today that our schools all across the country have ticking time bombs in them."
The goal of his initiative, which he serves as executive director, is to bring isolated kids out of the shadows.
