Shoshana Walter is a staff writer for The Marshall Project, working on investigations. Previously, Walter was a senior reporter at Reveal from the Center for Investigative Reporting, where she examined the armed guard industry and trafficking on marijuana farms. She uncovered how court-mandated treatments for drug addiction turned thousands of people into an unpaid, shadow workforce for some of the country’s largest corporations — reporting that was a Pulitzer Prize finalist, and which led to the popular investigative podcast “American Rehab.” Her work has been honored with the Livingston Award for National Reporting, the Investigative Reporters and Editors medal, the Edward R. Murrow award and the Knight Award for Public Service, among others.
