I am NOT an attorney.
I still don't have the needed information.
First you said 2 charges, now there are more than 2. A lot of what you "know" about the whole deal is conjecture on you part. Because all the crimes that you have so far enumerated have to do generally with theft, it may be that the increasing severity or the sheer number of repeat offenses (not the total number of offenses charge) enabled the DA to press for more time.
To answer your questions and possibly assist this person I need detail, detail, detail. And apparently you don't have them.
If you are willing to divulge either his first and last name and year of birth ,or his DOC inmate # to me in a private email, maybe I can get the details. DO NOT POST ANY PERSONAL INFO ON THIS SITE.
If you want to do that just post that it is ok to send you an email.
Also, you didn't say anything about the appeals. I suspect he has made no formal appeals. Notwithstanding the fact that there are many lawyers in jail now, certain prisoners have become very astute in the practice of law and I'm not just speaking of a "jailhouse" lawyer stereotype either. Perhaps he can enlist their aid. I would imagine the PD may be require to file appeals for him, but don't know for certain.
