New to Websleuths, first time poster. Hi everyone! I've been reading along for a few weeks. I'm on maternity leave and this has been a welcome, albeit disturbing and at times painful, distraction from the monotony of caring for a newborn.
I'm on board with the theory that this murder was a contract killing, and I believe the hit man was probably hired by her husband. Here's why:
1. Motive. We've learned now that MB and/or BB were involved in extramarital affairs. There were also financial concerns. Even if only MB was having an affair, or only BB was having an affair (since the SW is not, IMO, clear on this), that's enough motive. As far as the financial motive goes, I think it's safe to assume there was a life insurance policy at play, even if it wasn't a huge amount of money. I just don't think anybody else has AS MUCH motive, given the limited facts we have available to us.
2. <modsnip>
I believe way too much emphasis is being put on this perpetrator being some sort of super smart stalker who planned this crime out down to the minute. I think it's much simpler. S/he knew MB had a CG class, probably knew MB would arrive way earlier than the other CG campers (as we've learned is required by all the trainers, right?), showed up early by car to "prepare," murdered her, hopped in his car and drove away. I don't think s/he knew that other campers would arrive as early as they did, but escaped without being seen anyway. Luck. I don't think there was an accomplice waiting nearby in a getaway car or anything. We also know from LEO that the murderer's vehicle (or a vehicle we can assume was the murderer's vehicle) was caught on camera. So all this talk about a motorcycle or leaving on foot, etc., makes no sense to me. The simplest explanation is usually the right one.
I also don't buy the idea that this murderer is really athletic. In fact, I believe the opposite is true. This person does not seem to move gracefully or easily. S/he sort of lumbers slowly, in the video we've seen, and the feet splayed outward does not indicate to me someone who spends a lot of time working out, running or playing sports (where feet being square to the shoulders is a big deal to avoid injury). This does not look, to me, like an agile, athletic person capable of outrunning someone light and fit like MB. Sure, s/he's bigger and probably stronger by sheer weight/force, but I think MB would be able to outrun or outmaneuver this person with relative ease (again, given the video footage we've seen). This implies, to me, hiding in wait or perhaps using a gun.
The part that's messing with me the most is why the murderer is dressed in SWAT gear. If I, a woman, showed up at a church to teach a workout class at 4 AM in total darkness and heavy rain walked in on 1 person dressed in head-to-toe SWAT gear (only 1? Why would a SWAT officer be clearing a church alone?) that would in NO WAY calm me down and make me trust the person. I'd probably scream and run away, and assume it was someone there to do me harm. That's terrifying! Maybe the murderer is dumb and thought dressing this way would inspire trust, but come on. I think it has more to do with hiding his/her identity, either from MB or the cameras. Or both. But that could've been accomplished with a ski mask, so impersonating a LEO seems over-the-top to me. I don't understand it.
All of this is just my opinion. Hope I didn't violate any rules! Tell me if I did so I can be better next time!
