I seem to recall similar stories from Louisiana and Florida, except the Florida one also involved digging up bodies from unmarked graves around the "boot camp" for delinquent juveniles. My memory is suspect, so maybe do your own research.

There's also the movie "Holes", the book it was based on, and the reality it was based on. "Boot camps" are plagued with corruption, abuse, and neglect all over the US. Wherever you are, if you dig deeply enough, you are likely to find someone profiting from children's misery.
