MOO/speculation:
Although I still think that there is perhaps a religious reason or cult belief behind the seeming "urgency to re-marry" which we have seen with Lori and CD, AC and ZP, MB and IP, and possibly others (conceivably having to do with a Jul 2020 end-of-the-world or invasion event - or some other requirement that they "gather" quickly, or return to a city of refuge, or build a tent city, or go to Zion, or whatever - before such an event happens), I think those who have suggested that we should "follow the money" - not so much in regard to the divorces, but in regard to the deaths - might be onto something.
Although it occurred before Lori got into CD's books, she did receive $75,000 as a result of JR's death. If Lori knew in advance that she was going to receive $75,000 in the event of JR's death, that would have possibly provided at least one motive for her wanting him dead (among the other reasons which have now been identified: the nearly decade long custody battle for Tylee, JR perhaps wanting to terminate other financial assistance or payments to Lori related to divorce, etc.). Maybe there was even still a threat that JR might choose to sue AC for the earlier taser and physical assault (though I admit that by then several years had passed). Just speculating.
And if Lori thought she was possibly in-line to collect $2,000,000 as beneficiary of CV's life insurance policy as well as possibly inherit a house (or 2) and several vehicles in the event of CV's death, that would certainly seem to have presented at least one very big motive for her maybe wanting CV dead [other motives perhaps included: maintaining custody of at least JJ (and otherwise avoiding the loss of benefits), possibly avoiding having to give back (or split) the $35,0000 she stole from CV's business, her possibly avoiding confinement in a mental institution, her possibly avoiding felony theft charges with regard to vehicles, phones, laptop, etc., and of course her being free to marry CD]. Even if Lori learned (or suspected) that CV had recently changed the beneficiary designation on his 2m life insurance policies to someone else, she might have thought that CV likely attempted to redirect those benefits to benefit the children (which would then maybe allow those benefits to Lori in the event of the children's death..). Of course maybe he just cancelled the policies, idk.
If MB thought she would likewise receive insurance proceeds from BB's life insurance policies in the event of BB's death, certainly this would have possibly given her motive to want BB killed. At the time of the attempted shooting, I don't think MB had yet written the "I don't want the children" text, so she might have also been expecting to inherit BB's assets if he was to somehow die before they divorced. I assume MB may have also wanted BB dead just so that she could marry IP (in a hurry). Rather than "in-an-effort-to-claim-custody" of her kids (at least the 2 that were biologically her's), it could be that the real purpose of MB and AC's trespass at BB's parent's farm in Utah (which I think occurred before her marriage to IP) was to somehow do away with BB (and the kids..) - perhaps in a scenario not unlike that which ended CV's life ("self defense!"). Lori may have even given MB the idea ("see how this works?"). BB certainly feared for his life and the lives of his children.
If CD truly did raise the coverage amounts of TD's existing life insurance policies
and/or purchase additional policies on her life (though I don't think we know this to be a fact), that would certainly have given CD reason to want TD dead, or perhaps even to have her mysteriously killed. Setting up a phony attempted murder via a paintball incident might've been an attempt to mislead authorities into thinking someone was perhaps out to harm TD. And if he was planning to marry Lori (which in retrospect is now obvious), this would've also given CD reason to want TD dead (and in a hurry).
Just speculating.
In addition to the possibility that AC knew too much, Lori (and CD - as they had just gotten married) might've been in-line to benefit financially from AC's death. Who knows what life insurance or other assets AC might have had? Given the relationship between the two siblings, it would not be a stretch to think that Lori might've perhaps been in-line to receive life insurance benefits or inherit other assets in the event of AC's untimely demise.
Lastly (though there may be more that I'm not thinking of) Lori possibly could have even been in a position to benefit financially in the event of the children's death. It's pure speculation, but she might have assumed that any assets which the children had perhaps previously received following JR's death and/or CV's death would then go to her in the event of the children's death. She could've even had life insurance policies on them..
If stealing or raising money was perhaps the real motive behind some of these "deaths" (or possible attempted murders), the money might not have been just for Lori's, or MB's, or CD's personal gain. Maybe the money was being sought to help (them and/or others) "prepare a place" ahead of the end times which they apparently felt were right around the corner. Jmo.
