I wasnt able to stay as caught up yesterday as I have been. Ironically, I'm having to have a couple of days worth of meetings in order to deal with issues involving my own sibling, whom I believe strongly has NPD (narcissistic personality disorder). In trying to catch up on reading the thread something occurred to me. It has to do with wondering about HE's belongings she had with her (purse, watch, ring, phone etc) possibly being kept by TM & SM. It would seem ridiculous to us for them to have kept anything of hers, thereby incriminating themselves easily if said items were to be found. But here's the thing: if TM does indeed have NPD, she very likely thinks herself to be way smarter than LE and didn't think she could be caught. She may have also had a compulsion to keep something of HE's and that compulsion combined with the "magical thinking" that she was too smart to get caught may end up being her downfall.
My sibling has this same superiority or "magical" thinking. She believes she is THE authority on everything. She also seems to have a compulsion to keep things that belong to others. She takes/steals/borrows things from others and keeps them. I read once where they almost consider them trophies of how superior they are. She has done this since we were all children and she is much older than I. As an adult she has borrowed things but will lie about having them and will not give them back. For instance, she borrowed a book I have that was very special to me (it had an inscription). I hesitated, because I knew very well that I might not see it again. I felt guilty for feeling that way and against better judgment I let her borrow it. When I called to ask for it back she informed me to search online, that I could get another copy. She never admitted to having it, but it was clear I was not getting it back. Our other siblings can relate similar stories. I believe that she has a compulsion to take things from us to get back at us for having normal stable lives. She feels she's supposed to be the one who is better/smarter/stronger and it isn't working out that way. I have no doubt that she would take other things if she had access to our homes, which she no longer does in any way.
Just thinking about why TM would dare keep anything related to the crime or the victim. My sister can't let go of much. She's also a hoarder. TM could be totally different. But I do wonder.
