Researchers from the University of South Florida in Tampa found at least 50 grave shafts at the Dozier School for Boys in Marianna, Florida - 19 more than had been identified by the Florida Department of Law Enforcement in a 2010 investigation.
In total, scientists believe a minimum of 96 children - aged from six to 18 - and two adults died between 1911 and the 1973 at the infamous school, with many of the burials going undocumented.
And there could be even more victims: Researchers do not have access to records after 1960 because of privacy laws, and overgrowth on the grounds has hindered them from full searches. | Mail Online
