Right now, no one on the defense side is going to volunteer any information. Both the defendant and Miller are considered innocent of wrongdoing until proven otherwise. It will be the burden of the prosecution to get all the facts out through depositions and witness testimony. The only thing that's fishy right now is the text message exchange that Miller was part of, and whether or not Miller's car was somehow blocking the victim from escaping the scene. Whatever plea deal you're alluding to would happen later in the process when it becomes clear what the outcome of a trial would likely be. Miller isn't out of the woods, but everyone will assume he's innocent until shown otherwise.
