The person charged was never read his rights but cant prove it without a doubt that he wasnt. There are marks on the victims neck from where they were choked.
The "lowest" sentence for a CDV conviction would be a time served sentence. This is rare, and typically at least the Court will require payment of a fine (up to $5,000), counseling (6 months) or some jail time (up to 30 days). The Court can require a combination of any of these.
The sentence is only applicable if you are convicted. If you do not have a prior record you may qualify for pre-trial intervention (PTI). CDV is a serious enough offense that you should consult with a qualified attorney.
