BINGO! That's exactly what I think happened.
We have seen how hot tempered Stine is. Cold Stone temper---ate a quiet lunch with him then shot his life long friend 8 times at close range, then calmly walked away.
What could make him so extremely angry?
What if his wife was trying to leave him but was afraid for her and her daughter's safety? She couldn't just call the police because that would be of no help. So she reached out to her family friend for help----got the Judge to sign a Protective Order and they all exchanged numbers in case of emergency, if they needed help. The judge could get LE to go help with his one phone call, where the wife or daughter might be ignored if they called about an abusive Sheriff.
If Stine found out about the alleged protective order and his wife's plan to leave, he'd be furious at his friend for siding with his wife and daughter.
[A protective order is issued during the court process to protect the alleged victim in domestic violence cases. While the case is pending, a judge will order you stay away from the victim and to stop contacting them.]
