my daughters boyfriend is on parole

I am not clear on your question, as to whether it relates to the "punch in the eye" she took or the fact he left her place. It is her boyfriends responsibility to let parole know where he lives. As to your daughter as a victim of his punch, it is up to her whether to report it and how much to cooperate with the prosecution of his case. She can be forced to attend court and testify (via a subpoena) if he is charged, but she has to be served properly with a subpoena for that requirement to come into play.
