The National Press Photographers Association awarded the NPPA Humanitarian Award to Kathleen Flynn, an independent photographer and documentary filmmaker, for her career covering human rights issues and injustices.

The organization specifically recognized Flynn’s photography for ProPublica’s 2018 investigation, “Unprotected,” co-published with Time magazine, which looked into an acclaimed charity called More Than Me. Founded by American Katie Meyler, the Liberian school promised to rescue some of the world’s most vulnerable girls from life on the streets, but from the very beginning, children placed under its care were being raped by one of the nonprofit’s leaders.

Days after the investigation, Meyler temporarily stepped aside as CEO, and the organization’s board chairman resigned. Amid protests in Liberia calling for the government to revoke More Than Me’s accreditation and permission to run its schools, seven Liberian government agencies vowed to take action as part of a “full-scale investigation” into the charity.
