I am sorry that I saw this too late. You should have had the chance to seek refugee in the state foster care system. Diamond Ranch Academy is not a nice place. It is not a place for treatment either. It is to break you and boot camp in the army is water beside it.
I hope that what is left makes it out on the other side with just a little of your mind sane.
For more info if you know this person and wants to support him or her by arrange memorial marches etc. See the wiki database on Fornits. They have a datasheet about this specific program.
I am sorry that you didn't make it to the state foster system or even in prison. You would have so much better off.
