My question involves child abuse or neglect in the State of: North Carolina

My daughter (who is 3) came back from her dads with bruises from a belt all on her legs. I called CPS and she is not aloud to have contact with him until they say otherwise and they are now investigating this.

Law enforcement is also involved and said that most likely they will charge him with assault of a minor.
Since he is already a felon how badly will this hurt him?
I want to know the chances of him going to jail for this...
Does anyone think he could lose custody?
