Unfortunately it is very difficult in Michigan to get a court to reconsider a sentence. Your son would need to argue a legal reason that the current sentencing decision was not made properly, or that the court didn’t have right information at the time of sentencing. I recommend that you talk to a lawyer about this option.

Is your son eligible for parole, or will he be in the future? In this case, the parole board will consider his release. Family, friends, and other people who know your son can write letters to the parole board in advance of their deliberations to show evidence of how much your son has changed and how much support he has toward being successful after release.
