Gisborne, you must be worried sick. I would have a chat to his Barrister and see if the CPS would accept a Plea Bargain to reduce. It may be worth it even if its a long shot. If someone bottled my daughter I too would want a long sentence but you are a Mother/or Father and you are bound to be worried about your son.
My suspicions are a short term of imprisonment or a long period of probation, unpaid work in the community, a heavy fine and compensation.
If he DOES go to Prison, you will be able to still see him, make contact with him, write to him, take clothes for him and speak with him on the telephone. Although hard, everything becomes accceptable after a while and you will learn to accept it. Going to prison does not mean you are going to die or lose your son. Its a temporary measure.
Try to keep strong.
Love Katie. x
