I have some questions that Google hasn't been able to answer for me. I'm interested in researching and writing a book about a local unsolved murder. It's a tragic piece of my town's history that I grew up hearing second-hand (unconfirmed) facts about. I got the gist of the case but the specifics were never grouped together in one, easy to find place. A few years ago I decided to look it up and found a lot of information spread across the internet. It was a very high profile case but no one has published any definitive collection of the facts of the case in one place (save for some news articles and interviews). I'm wondering though, what is the etiquette of writing a heavily researched true crime narrative nonfiction account of the events that happened in my town? Do I need to have special permission to write about the subject if intend to try to get it published (it's early but, that is my longterm goal)? Or can I independently research it, map out the book and shop around a manuscript? Could I self-publish it in ebook form or does the true crime genre change that? I assume I can research and write out as much as I want, but I just keep feeling like I need to get some kind of special permission at the outset of the project in order to tackle it. Obviously the research would include digging up old newspapers and talking to some people who were involved with the case. It would be an entirely fact-based book but I don't know if there are any legal hurdles I need to jump before I get started.
