Incidentally, in many states, a person is only considered a minor if he is 16 or younger. For certain crimes, a 17-year-old may be charged as an adult, and will face adult penalties. I don't know the specifics for Indiana, and it's too late for me to be up searching (7:00 AM comes real early). But, see this site for a list of Legal Aid sources in Indiana:
