Back in some early threads there were several posts discussing CV's divorce filing, the protection order, the 72 hr mental health hold, and the claims made by CV to KVW/LW and to his attorney (including the infamous "if anything happens to me, Lori and Alex did it" declaration). There were also posts discussing CV later withdrawing the divorce filing, hoping that he and Lori could somehow work things out.
In one of the thread #2 posts there's a reference to a GH video in which CV's life insurance policy (or policies) is discussed - noting that there was a 2 million dollar benefit, and that perhaps CV had removed Lori as beneficiary in the midst of the divorce filing and all the related PO and hold-for-observation turmoil.
Do we know what CV's final actions were on the life insurance policy? Did CV remove Lori as beneficiary (as was mentioned in the video), or did he remove and then reinstate her (in concert with the divorce)? Did he cancel the policies, or did he perhaps change the beneficiary to the kids (maybe to a combination of his children from prior marriage and at least JJ - and maybe Tylee)?
Obviously, if Lori thought she stood to collect 2 million in the event of CV's death, it offers a motive. In fact, even if CV removed Lori (and she learned of it) it might suggest motive (though a different one).
If the kids however were about to (or did) receive a lot of money (whether Lori knew about it in advance of CV's death or whether she found out afterwards), you'd think she would've kept the kids handcuffed to her. If JJ (and possibly Tylee) died, would Lori have collected JJ's assets as next of kin? But even this makes no sense, as JJ has disappeared, not been found deceased.
Edit: Posted right on top of J Lum, which I just read. So I guess amount of policy was 1 million - unless there was more than one policy
