Three of the finalists describe the grueling selection process and the tragedy that killed one of their own. One Year is produced by Evan Chung, Sophie Summergrad, Sam Kim, Madeline Ducharme, and Josh Levin.  Derek John is Sr. Supervising Producer of Narrative Podcasts and Merritt Jacob is Sr. Technical Director.
