FWIW, I can never get a complete answer to an entire alternate theory. As soon as a question pops up, we go back to someone else lying on the stand. Or what a heinous individual BZ must be. Or something that was eaten. Or not eaten. Or ducks. Or Facebook. At this point, the best I can work out from the SODDI folks is that JP did it to avoid child support although there seem to be no DNA test results in existence to support this - he either met her at Java Jive where she brought a child to prove its existence, or he abducted her into a van when no one was looking and made a beeline for Fielding. JA covered for him because she was mad at NC for having a friend who had the same name as her own husband and didn't get invited to the same party.
This posts a little to snarkery, but I'll bite.
The defense (and most of us) are not presenting an alternate theory.
The alternate theory is that there WERE alternate theories. No one is claiming to know the truth but the BDI folks.
We have a problem with the state's version of BDI because:
1) Brad had means (Well, yes, he had hands) Brad had motive (okay, he was getting divorced, and gonna be out a lot of money) Brad had opportunity (if you can tell me the REAL timeline, which has about six versions going here from all sides, I will try and narrow down what the state is saying. I'm going to pluck 1:30-2:00 am out of the air for a moment.
2) The CPD has been proven to have a lot of contradictory stuff going on. Depending on where you stand: A) It's a series of unfortunate and honest mistakes that would be caused in the course of any investigation or B) it's a series of events that resulted from hearsay, gossip, tunnel vision and the inability to aptly investigate a crime that went from missing person to homicide, coupled with a complete lack of understanding of the importance of the technological aspects of that investigation until some key pieces of evidence were potentially invalidated and made "unpristine" (to quote BZ) and thereafter inadmissible.
3) BZ is not a terrible person or whatever. He's a dishonest prosecutor. His boss will see it in the live feed. He has said (on what I count as four different occasions) things that he then contradicts with his efforts at cross examination to a sitting Wake County Superior Court Judge that is less than interested in furthering his own understanding of various aspects of technology that are pertinent to this case. Leaving these things unexplained is bad. Directly misleading a judge on a live feed for a home audience is inept and possible career crippling.
4) Kurtz and Trenkle don't KNOW what they are trying to say with the alternate theory because the prosecution and the CPD made a very big muddy mess of the actual evidence and the following theories have been floated:
1) Someone did it to NC because of a paternity/child support privacy issue.
2) A woman (or women) familiar with NC did it for jealousy or other reasons unknown.
3) It was a random act. (Shot down frequently here, but it COULD have happened)
These are separate and clear cut theories that are supported by the general framework, but TWO of them would have required the cell phone of NC to be proven.
5) The gossip and hearsay angle muddying this case has become a very large portion of the alternative theories game we play. Why? Because the friends (per Mr. HC) look like lying liars who lied.
6) Some of the "important" lies we fought about early in the case and some of the issues we batted around included: The ducks and sticks, the color of the dress and possible obfuscation by BC, the necklace, the lack of money. Then we see NC on her next to last day in a store (with money) in a black dress (the color of what BC remembered) without the necklace (she never took off).
7) The google search. I think this is a piece of evidence that some consider to be THE smoking gun. I think it's hogwash. I think it's too convenient, too precise and bunk. Why? Well, you tell me why it took so long to find it and whatever other information is around it and I'll tell you why. Until they do, I beg off. It's irrelevant in my idea of keeping the trial fair because the defense should be allowed to kick it.
8) The router info from Cisco. Another item they have had YEARS to come up with and MONTHS under court order. It just conveniently appears...it's not helping me. Couple it with #7 and I go...no way.
9) The video depositions. Seriously? Let's assume for an instance that AS did not consult with the Cary PD to get an impromptu homicide interrogation going. What is the point of the custody mess being brought into this?
10) The cleaning charades. This is all bunk. The prosecution played a polite but firmly infuriated voicemail of the VICTIM in this case pointedly discussing her anger at the state of her house's cleanliness. And yet...we question why a man was cleaning. I'm sure she just blew that off and said nothing to Brad. Riiight. She tore him a new one. She said: I'm calling the realtor and I'm leaving today because I can't live in this FILFTH any more.
If it weren't for JA and DD, this might have been a slam dunk, but going and saying: Oh, no. I WILL TALK TO THE POLICE. NOT YOU! Doesn't that raise your flag a bit?
This, coupled with a phone call to local police, after a friend is missing for only a few hours places her firmly in the top of my lists of things the CPD missed. Why call the non-emergency line at 2:00 on a Saturday when your "plans" are suspect?
So, to clearly and concisely answer your question about the alternative theory: Take your pick. This mess (courtesy of this mess) is a free-for-all that only makes sense if you subscribe to the often true, but daring to be disproved theory: The Husband did it. Because eventually, that theory is going to start to be discounted because it will become the framework for getting away with murder (just make sure to make it look like the husband did it, right?)
Also, the behavior from most of the pros witnesses regarding the NC and BC interaction is the biggest part of this mess. Were they in need of Interact's intervention? If so, why just the two folks going after that? Where did all these "bad feelings'" come from other than from the weird state of things? I don't think "bad feelings" count when you are trying to get a good measure on the items listed above.
But I know this....I hope to whoever is upstairs that the GJ stops indicting based on anyone's "bad feelings" because we are ALL in trouble at that point.
