RE: Need help - pre-sentencing letter to judge
Pappy basically said what I was going to say. I do have experience in this, as my youngest brother was arrested and sentenced on drug charges (he has been clean and sober ever since, thank The Maker). The family didn't write a letter, but we met with his attorney and told him about our brother, what he meant to us, and most importantly of all, what role we would play for him while he was in jail, and after he got out. I was fortunate in that I had a friend who was the director of an alcohol/drug treatment center, and I secured a grant for my brother to go there once he was released from jail. Oh, and we showed up for his sentencing, so the judge could actually see that we were there supporting my brother. Are you able to go to the sentencing hearing?
As pappy said, don't sugar coat anything, but do talk about what is positive about your nephew, AND what kind of support you and others in your family are willing to provide to him. Obviously, your nephew has to want to turn things around, but people really can't do that all by themselves. If the judge hears that a) you know what his problems are/what kind of trouble he's in, and b) what you and other family members are willing to do to support your nephew, it could go a long way in the eyes of the judge.
Best of luck to your nephew and your family.
