I'm wondering the same thing. I'm grateful that Marshburn did what LE was apparently unable or unwilling to do. He found Lucas. I think there have been people who have been (and possibly still are) looking for personal glory from this case, but I don't get that vibe from him at all. I followed the Kelli Bordeaux case and I never felt he looked for Kelli for personal gain, either. He's rough around the edges, given that he's not a trained PI. He's essentially a bounty hunter who discovered he's good at finding bodies that LE can't or won't look for. I don't see where he's jeopardizing the case, but that's just my opinion.
