For decades, relatives of some boys dispatched to the notorious Arthur G. Dozier School for Boys have struggled to find out what became of them after they went missing amid reports of beatings, torture and sexual assaults at the reform school in Marianna, Fla.

On Tuesday, researchers and forensic anthropologists moved a step closer to providing answers. The remains of 55 people have been uncovered on school grounds, University of South Florida researchers announced – five more than previous field work had indicated and 24 more than listed in school records.

Historians say at least 100 kids died at the school, and according to a former student some bodies were burned or dismembered postmortem. We may never find all the boys who disappeared.

Steel yourselves if you decide to keep reading, GT. This shit is a horror show.
