The trial court judge cannot help you because he or she was divested of jurisdiction after sentencing and any motion for new trial. His sentence is within the statutory sentencing range and the reduction you are seeking is well below what he is eligible for with good time. Because he pled and the sentence is, on its face, legal, there is almost certainly no appeal or post conviction relief opportunity to reduce the sentence. At least two years of a forcible rape sentence in Louisiana are not subject to probation, parole, or suspension of sentence. The trial judge could have made the entire sentence subject to those limitations, in which case parole is simply not an option. All that would be left is a petition for a commutation of the sentence by the governor. He can certainly request that, but it is likely a long shot given the nature of the crime and your age at the time of commission.
