Sari Horwitz is an investigative reporter who covers criminal justice issues for The Washington Post where she has been a reporter for 38 years. Horwitz has been awarded the Pulitzer Prize four times. In 2002, she shared the Pulitzer for investigative reporting for a series exposing the District of Columbia's role in the neglect and deaths of 229 children placed in protective care. The series prompted an overhaul of the child welfare system and a new wing of D.C. Superior Court for children and families. Horwitz also co-wrote an investigation of D.C. police shootings that revealed that D.C. police officers shot and killed more people per resident in the 1990s than any other large American city police force. The series won the 1999 Pulitzer for public service and the 1999 Selden Ring Award for investigative reporting.
