Was actually just looking for a 'ballpark' idea of what he was facing but thanks, will see if I find anything in there but guess the final punishment decided on will in large depend on the particular circumstances.
Random googling shows up a couple of results that say you can't get more than ten years for theft. No idea whether that's true or not and I'm not sure what his exact formal charge will be.
I wonder whether being in jail will actually register in his autistic mind.
