For more than 100 years, boys sent to the Florida School for Boys were beat, tortured, raped, and killed. Opened in 1900 in Marianna, FL, the school finally closed in 2010 after a U.S. Department of Justice investigation found rampant abuse at the school. Students sent to the school had behavioral problems.

In 2014, the University of South Florida started excavating the former school site and found a mass grave of at least 50 bodies. The bones were of students who had gone missing without any record of their death. Other evidence surfaced of unspeakable horrors. In the 1950s and '60s, a group of boys who called themselves the White House Boys were repeatedly raped and whipped. They filed a lawsuit in 2010, but the statute of limitations had run out and the suit was tossed. In the 1980s and '90s, boys were hogtied and put into isolation for weeks at a time. One boy lost an arm after it was forced into a washing machine.

What's most shocking is that state and federal government officials were aware of the abuses at the school dating back to the 1960s. Despite multiple lawsuits and criminal charges, the school was not shut down.
