19 Years Later, Columbine Survivors Reflect

Heather Martin and Zachary Cartaya's nonprofit, The Rebels Project, works to connect survivors of mass shootings to one another through a private nationwide network. The group also arranges trips to grieving communities after national attention has faded away, and flies survivors out for a national gathering each year. HuffPost Reports met with the leaders of the Rebels Project as they visited the Columbine Memorial in April.
