How Much Has to Be Figured Out Before You Can Start Writing?

For me, I have a tendency to just start writing. And figure it out later because I like to kind of immerse into the story. When you're doing the research, we're spending time with FEI agents, medical examiners, the Nashville police. This is just filling the toolbox so that when you're then writing, you can say things right or wrong. That's not rocket science formula to sit down and work out on a day to day basis.
