Friedman & Bresaw. In the more rural areas of NH, you need someone who is local because they know officers, the courts, and the prosecutors. From what you describe, it is a situation that needs good negotiation. Being local will help that.

I’d second Bresaw. He’s very good and has a working professional relationship with the police in that area. Super important in trying to get a plea deal, which is likely the route you’ll have to go. Pricey, but worth the money. I’m sorry by the loss you and your family are going through. You’re a saint for trying to support their son right now. I’m sure he desperately needs it.
