TALLAHASSEE, Fla. (AP) — Florida officials have agreed to survey the grounds of a shuttered reform school campus where dozens of boys are believed to have died.

State officials said Thursday they will survey the entire 1,200-acre (485-hectare) campus of the Dozier School For Boys in Marianna, Florida, for the first time.

The Tampa Bay Times reports the survey will use radar-like laser mapping data to detect abnormalities that warrant more on-the-ground probes.

In April, a subcontractor using ground-penetrating radar on the campus found 27 so-called anomalies that could be unmarked graves.

University of South Florida researchers have previously documented 55 graves near the school, though they estimate nearly 100 boys died there between 1900 and 1973.

The school closed in 2011.
