I really feel you guys are going down the rabbit hole on this.
There is not one single piece of evidence that DK murdered the McStays
The Prosecution has already twice given evidence of how he was cleared.
1 x documentary evidence
1 x direct testimony explaining that detectives worked the angle and eliminated him
What more do you want?
Ok wait. Let me make myself clear. I believe that Chase did this. I want to see the State prove it, and we all should want that, don't leave any loopholes. We all know that if he is convicted, there will be appeal after appeal. Part of proving he did it is investigating ALL leads, thoroughly IMO For myself, DK and Chase have the same motive, money, so from there, it has to be investigated, LE says they did, the defense says no way. I have not seen any evidence yet that proves either one.
There is no documentary evidence as of yet, and since when do we take someone's word for it that it exists? Never that I know of. It's like saying they can put an officer on the stand, that officer can say that Chase wrote cheques and deleted them, but never showing us with computer forensic evidence. Or that he cashed cheques, withdrew funds, etc but never show us the proof of that.
The DK rabbit hole was dug a long time ago, and IMO he started the digging all on his own. Not going to lie, I can't wait to see the little creep on the stand squirming, regardless of whether the state or defense proves he was in Hawaii or not, I want to see him squirm when they ask him about the money, the sale of EIP, the text messages with Joey, the buy out, etc. I cannot wait to hear his answers. Afterwards, we are either going to be left with some questions still, or those that think he might still have something to do with the crime will feel satisfied that the little creep didn't have anything to do with it and will hopefully end any questions.
IMO if the State has evidence, put that officer that interviewed him and received that evidence on the stand. Have him say it, show the proof and it lessens the theory whenever the Defense keeps bringing it up. Every question that gets sustained is still heard by the jury.
