A team of University of South Florida anthropologists on Monday plan to announce the findings of additional graves at the former Dozier School for Boys, a state-run reform school in Marianna.
The school was closed last year after years of reports and a state investigation revealed a pattern of severe beatings and torture of the youths sentenced to stay there.
A group of former students from the 1950s and 1960s known as "The White House Boys" allege they were subjected to repeated physical abuse and that fellow students died from abuse.
The property contains a cemetery with 31 metal crosses, but school records show 84 boys died at the institution between 1911 and 1973.
USF researchers have spent months mapping the school's cemetery using ground-penetrating radar and other methods to identify the numbers and location of graves in the cemetery and answer lingering questions about what happened to the boys.
The USF team has identified a number of anomalies indicating potential grave sites in wooded areas outside the marked cemetery.
The USF researchers will release and discuss their latest report to the media Monday morning at the Patel Center for Global Solutions on the Tampa campus.
