So many unanswered questions.....I think LE is definitely keeping some information from the public for the purpose of the investigation. I wish I knew the footsteps of the family on that day. Denise and Jayme attended a family party, but we don't really know who was in attendance. James had to work that day. Did he work his full shift? LE released the description of the two vehicles in question in the area on that night. Strange that nothing has come of that. With all the resources available in the beginning of the case, one would think that LE was able to go through the entire DMV records in Wisconsin and follow up on all those vehicles. IMO I do feel it is someone that a member of the family knows. On the outside they appear to be a small happy family, but we never know what goes on behind closed doors or any of the family dynamics. I read about Denise being devoted to Jayme, but I never read any reference to the father/daughter relationship. Very few family photos released. Sad case.
