No one can answer that with certainty, and anyone who tells you otherwise is not being straight with you. What we can do is look at the situation clearly and talk about what actually protects people in your position.
A conviction for murder combined with a subsequent protective order violation tells you something important: this is a person who has demonstrated both the capacity for lethal violence and a willingness to disregard legal boundaries meant to keep someone safe. That combination deserves serious weight, not reassurance.
When someone with that history comes up for parole, the parole board will consider factors including institutional behavior, program participation, and risk assessment scores. What they cannot fully account for is what happens once he is back in the community and encounters the people connected to his past. If you have any standing in the process, such as victim notification rights, you are entitled to submit a statement and be informed of his release date and supervision conditions. Contact the Arizona Department of Corrections or your state's victim services office to make sure you are registered in the victim notification system. Many states use automated systems like VINE (Victim Information and Notification Everyday) that will alert you the moment his status changes.
On a practical level, the protective order may still be in effect, but a piece of paper only works as a first line of defense, not a last one. Consider whether your current address, workplace, and daily routines are known to him or his contacts. Distance, changed routines, and a updated support network are not overreactions. They are reasonable precautions.
You are not being paranoid. You are being realistic about a situation that warrants realistic thinking.
