Human bones have been recovered from woodlands in Florida where juveniles who disappeared from a reform school are believed to have been buried more than half a century ago.
An anthropologist from the University of South Florida says researchers have found evidence of hinges on coffins and shrouds consistent with the 1920s and 1930s.
He says human bones were also found but it is impossible to know if they came from any of the teenaged boys who were housed at the Arthur G. Dozier School for Boys.
The school closed in mid-2011.
Reuters reports that a number of former residents of the school, who are now in their 60s and 70s, have told of brutal beatings and boys - mostly black juveniles - disappearing without explanation.
