When Elizabeth Smart was kidnapped her younger sister was in the bedroom. She saw the kidnapper but it was months before she remembered he was a homeless person who had done work for them.
I think sometimes a person can be traumatized and just not remember everything right away. Maybe that is what happened to Kelsi.
Thank you so much for you're thoughts on this. It is absolutely true that the mind can forget things when faced with a tragedy of this magnitude. I remember wondering if my thoughts and memories were real or imagined when my daughter was abducted and found murdered. I suspect this has happened with the entire family of both girls. It's just too horrifying to be real. While we may be thinking about/identifying their inconsistencies, for them it may be a new (or improved) memory. No deceit involved.
It's terrifying to have a chunk of your memory missing due to trauma. It does terrible things to one's mental and physical health. When memories first begin to reappear, one may (again) question if they are real or imagined. Are we (subconsciously) so desperate for answers that we made ourselves think the thought(s)? Are we imagining there was a black SUV with window decals? As time goes on, we begin to start trusting our memories. We embrace what we know is real. We feel comfortable in sharing those memories with others- sometimes without even realizing it. We continue to heal, and regain what was lost.
It is my belief that this is what is happening with KG. (BP addresses KG's state of mind for the first year following the loss of her Sister in her YouTube interview with Tricia). I have no doubt she will continue to grow, and use her memories to help others. Maybe even her own Sister, by remembering something that was previously forgotten about that day.
