The name Chandra Levy is now mostly forgotten, or prompts questions which begin: “Wasn’t she … ?” But in the summer of 2001, she was the most famous missing person in America.

Levy arrived in Washington, D.C., the previous September and began a six-month internship with the Federal Bureau of Prisons. She was 23, from the midsize city of Modesto, in California’s Central Valley. Bright and ambitious, she breezed through San Francisco State University in three years and was in her final semester of the master’s program in public administration at the University of Southern California.
