Dozier boy's school had a sister school in Okeechogee. The same thing was happening there. The claimed to search for bodies and find none but the land where witnesses reported to have seen the graves was not searched. The article says the foundation of the old Dairy where they buried the bodies was still visible. I can see it on google maps. The new land owner wanted them to search his land but they didn't. The land is on old cemetery road.
