In the summer of 1981, 6-year-old Adam Walsh walked into a Sears store in Hollywood with his mother and never came home. What began as a frantic search for a missing little boy quickly became one of the most heartbreaking and infamous child abduction cases in America. The tragedy not only devastated a family, but forever changed the way missing children cases are investigated, turning Adam’s father, John Walsh, into one of the country’s most recognizable voices for justice. Decades later, the case still haunts the nation as a chilling reminder of how quickly innocence can disappear.
