Just speculation but here goes!
The search warrants are currently sealed and not available to the defense for another week or so. These seals can be extended but I would think that the State would have to give a good reason why to justify the extension. These arrest warrants show that the investigation is active and ongoing but its slow going. The latest arrest warrant deals with events from June and there are clear gaps in much of the information in the warrant so there is much that LE has been working on that needs to remain secret/sealed so the investigation can continue.
I also believe that as we saw in the MT warrant that she lied for 2 months to LE and was just starting to cooperate slightly as of 8/13/19. This is a recent development and she no doubt has much to share if she chooses to. But based on how I thought her Atty looked at her latest bail visit and the fact that he felt compelled to say that she should be presumed to be innocent (after saying that his personal policy is NEVER to speak to the press on active cases) told me that he has a very very rough row to hoe to get MT to cooperate with the State. My guess is that MT lied to her atty as well as the State and this has put Bowman in a very awkward position as its not easy to represent a liar who most likely is involved with the murder of JD. If MT is choosing to lie because her mother is telling her to do so to wait for a better deal, I would encourage MT to ditch her mom and listen to Atty Bowman, as otherwise she will lose custody of her daughter as she will be spending the next 20 years to life in prison. I also question whether Bowman can stand by MT after what has happened but we shall have to wait and see if he files to be excused from representing her.
This gets to my last guesses as to why more charges now.
The more charges the more potential prison time so if charges can be stacked it might make sense to do it as so far there is no JD body. Murder trials with circumstantial evidence are tricky operations and the State has to present a perfect case to get it right to win a murder conviction for FD and possibly MT. More charges give some leeway that if murder cannot be agreed to by the jury that a long sentence is in store for FD and MT for the other stacked charges.
Reading through the arrest warrants its clear that any number of other charges could have been brought by the State but they didn't. An easy example of this was MT lying to LE which is punishable by prison and yet she wasn't charged for it (YET and this is impt too because they can bring it at a later date if she doesn't stay on the straight and narrow IMO). But the arrest warrant is an official document and it clearly states she admitted to lying to LE multiple times over a 2 month period. Mmmm. Sucks to be MT right now!
The charges also documented in technicolor to Pattisville that the State knows where FD was on the 24th and what he did. No Case Norm has been coming up with off the wall theories for months now including that MT was going to be FD alibi. Well now, all this is off the table and Pattisville actually has to do some legal work to defend their client in court and their flimsy motions to dismiss will no longer fly IMO.
I'm sure there are many other ideas but I am sure it will become clearer as we move on to more charges at some point.
MOO MOO MOO
I was shocked but not surprised when I heard FD say he thought his wife was still alive. Of course, in the very same interview he used the past tense when referring to her. Oops, he forgot to stay on point with his Alibi Script! Can I again mention that pesky rash, and I don't mean the poison ivy rash, that pops up on his neck during every interview I have seen of him? That was a tell IMO. A second tell mentioned by another poster was his speech- very slow and controlled. He didn't want anything to slip, so he was trying to moderate tone and delivery. Polygraph operators see this all the time, but what the subjects of those exams do not understand is that good poly operators look for such signs as indicators that the subject of the exam is lying. He can control his speech, but he cannot control his body's physical response to his lies.
Allowing FD to continue on his publicity tour is one of the dumbest forced errors I have seen in awhile. Every single statement he makes is coming in at trial, and for him to say he thinks Jennifer is alive? Seriously? Dumb, dumb, dumb. If he truly thinks Jennifer is alive, why did he wash EE's truck without EE's knowledge, paying cash to do so? Why did he insist EE change out the seats? Why the Alibi Scripts? Why his refusal to cooperate with LE? It seems if he TRULY believed Jennifer was alive, he would be Johnny on the spot in assisting LE. After all, if he could actually prove that lie, he would have those kids he claims to love so dearly.
IMO, the novel Gone Girl is relevant to this case, however, just not in the way FD anticipated it would be. He read that book or saw that movie and said to himself, "That's the way I'm going to do it, make everyone believe my sorry wife abandoned our children to spite me. Everyone will feel sorry for me, hate her, and with the kids' trust money, MT and our happy family will ride off into the sunset." This certainly would explain him parking that truck where he did.
I believe he used the EE as his back-up insurance policy in case things did not go according to plan, which they clearly did not. FD had no idea all of his travels would be caught on video from the neighbors' cameras to the bus cameras to the cameras on Albany Avenue to the cameras at the ATM, and even the cameras at the carwash. He was so stupid he drew cash out of the ATM to hide his tracks and didn't even consider the cameras at the ATM! Don't even get me started on his ignorance about cell phone evidence. With that evidence not in the picture, EE could well have been considered a suspect.
Time and again, from his ill-conceived interviews to his sloppy mistakes throughout the commission of this crime, FD told on himself. This latest interview is nothing more than the same type of thinking that led FD to convince himself he could commit the perfect crime in the first place. The next time he is taken into custody, it will be for first degree murder IMO. He just wasn't the criminal mastermind he thought he was.
