So sorry this happened. I lost my brother to a car accident in '93 so I understand all too well what your family, and his, are going through. Godspeed, and condolences.
I'm very sorry to hear this, I can't imagine the pain you and your family are going through. My thoughts are with you all through this really tough time. Losing a family member is a worst nightmare for just about anyone.
Josh, You don't know me from Adam, but please accept my sympathies and prayers for your family. Scott
