Sandy Hook Promise has launched a free program to help students and educators learn the warning signs of suicide. The Newtown-based group says its suicide prevention program is the first of its kind to provide separate materials for school kids, parents and educators.  Cofounder and managing director Nicole Hockley says youth suicide is becoming a public health crisis in this country.  She says it's a trend they're seeing reflected every day in the types of tips that come into the crisis center of the organization's Say Something Anonymous Reporting System.
