Was he charged with a federal crime or a state crime?
It is probably a state charge.
However, it is never "automatic".
He can still challenge the confession, challenge the evidence, there may be a problem with the statute of limitations, etc.
It's usually the same charge. However, depending on what statute it was charged under they could use a different term for a different age.
There is a difference between a child under 14 and a minor between 14 and 16.
The statute website appears to behaving problems right now but I know there is a difference.
It could possibly be suppressed. He can still put up a defense despite having confessed although, of course, it would have been better for him not to have said anything.
What do you mean by that last one?
It carries a different penalty. He could be charged with both incest and the other charge but he could only be convicted of one. You can see the information on the incest charge at this link.
Yes, it is extremely likely that he would.
Best wishes to you.
