For Jerry Cooper and the friends he knows as the White House boys, the memories never fade. The brutal beatings, rapes and other physical and psychological abuse they endured at a notorious Florida reform school were more than half a century ago, but there is always something to trigger the flashbacks. This time, it was the discovery of 27 "possible" graves at the site of the Arthur G Dozier School for Boys in Marianna, Florida. It is no surprise that more victims of systemic, decades-long sexual abuse and violence could still be in the ground. A study that ended in 2016 saw University of South Florida (USF) anthropologists uncover human remains in 55 graves, several with gunshot wounds or blunt force trauma. Yet to the White House survivors, named for a whitewashed cottage in the grounds of the state-run school where the worst of the abuse took place, it was confirmation that the final chapters of a dark episode have yet to be written. "I was sure I wasn't going to survive," said Cooper, 74, who spent two years at Dozier as a teenager in the early 1960s. "But there were those of us who didn't ... there's a lot more boys dead than the 55 they located. We've always known this." Official records, poorly maintained and incomplete, indicated 31 burials from 1914 to 1973. But USF researchers partnered with local and state law enforcement and the University of North Texas science centre set the figure at a minimum of 98.
