If someone was serving a felony sentence in where they had served 120 treatment and released to serve probation or parole.
Does their status of still actually being property of d.o.c. change the laws of statute of limitations or the right to a speedy and fair trial?
While I was on probation I slipped up and sod drugs to an undercover. That was July of 2016 . I wasn’t charged or even alerted to pending charges at that time. In fact I got a successful release from D.O.C in October 2016. The has been my clean date also because I figured if they had something on me they would have to charge me before release. Jan 2018 I was charged. I’m currently in preceding now. One page of discovery was given and an offer of 10 years. No other charge but the one , and like I said I was sure it was all in the past and my entire life is completely different from 2016.
How can the department of corruption I mean corrections have me as their property and not charge me before I was released? That doesn’t make sense to me. They shouldn’t have been able to successfully release me while I had committed an offense a felony. They are charging me as P.&P because of the aforementioned charges and charges I had gotten 20years before that. So the offer of 10 is great. Except reals

The prosecutor has 3 years to bring charges for a felony; why they waited is irrelevant. You need to speak with a criminal defense attorney NOW. Posting insults and facts about your case online is not going to help you.
