Crazy treasure hunter is stalking me and my family to unpublish a book I just wrote.

Location: Mesa, Arizona

I recently wrote a book on my interpretation of several maps about the Lost Dutchman Mine. I pinpointed a location and went there. I took photos, matched it to all the clues and self published a book. I printed out about 100 copies to sell and offer them to local LDM museums to sell as well. I dropped off one book for the curator of the museum to review and see if they wanted to put it on their shelf. I get a call the next day from some guy who “happened to be behind the counter” when he saw my book with a sticky note on it with my phone number. He was curious and flipped through the pages and flipped out. I guess I pinpointed the location that his supposedly psychic grandfather had said and he and his family were looking for over 50 years (combined). I guess they didn’t know how to read the maps and were off a little. Anyways… he wanted me to unpublish the book because it will cause him great distress. I said no, but he wanted to discuss it. I figured “sure, I’d like to discuss my book with you” I was sort of thrilled to have someone’s opinion of my book and it was somewhat validating that we agreed on the location. He wanted to meet in the desert, near the Superstition Mountains.. I said no. We agreed at a coffee shop. My wife said I was being stupid and she is usually right about those things, but I went anyways. I just figured we would talk about it and find out where he family went wrong on their search. I was wrong on that. He offered me $25k to unpublish my book. He said he has a map from his grandfather where he circled some locations near by where he suspects to be millions in gold. I then just realized that I met one of the crazies that lurk in the Superstition Mountains. I told him that I will not unpublish, but I’d be happy to help him out get to his spots if he wants. He said no and got angry. I then promptly left and said do not contact me anymore. He then blew my phone number up with horrible messages so I blocked him. Then he went to facebook and did the same. I blocked him on there. He then found out my wife’s facebook address and started attacking her. I had her respond not to contact her anymore. I then unblocked my phone and sent him a message saying that I will pursue legal remedies if he continues and I will reach out to the museum to complain that someone was able to get that information about me from them. I then blocked his number. So, that’s the story. Can I pursue a restraining order on him in Arizona? Did he need to threaten me to do so? What are the chances of getting one? I was told that since he didn’t actually threaten me, it may not get rewarded.
