I agree 100% with your deductive reasoning. The only likely scenario in which she has survived is if she was the intended target all along and keeping her alive was paramount to achieving a long term goal. ( Jaycee Dugard- type case is all that comes to mind; maybe also Ariel Castro, I'm not so sure about his psychopathology because of his suicide before we had all the answers). As far as we know, cases like Jaycee's, Elizabeth Smart's, and the 3 living survivors of Ariel Castro are extremely rare in the USA. In some parts of the world, not rare at all because children, especially female children, have zero value. The odds are against a very publicized double murder resulting in a kidnapping with a surviving victim today. There was NO violence to others with the kidnapping survivors I can think of.. This is usually the case, though. A person enters a house to kill. OR, a person enters a house stealthily or stands on a street behind a bush or otherwise gains access to the victim. When there's been a scenario where two people have been killed and one left alive and unharmed, usually the violence was from within the house and perpetrated by the occupants onto police attempting a hostage rescue. I can't think of but one other case where there was a mixture of killing two parents, kidnapping their child ( or children), and leaving the child ( children) alive except the Joseph Duncan kidnapping of Shasta and Dylan Groene. From what I've read or heard on TV in Shasta's description of events, DYLAN was Duncan's primary target and Shasta was a secondary victim. Dylan was killed, and I believe Shasta's days on earth were coming to an end when she was recognized and rescued. I hope so much Jayme is alive and will stay alive until found. In so doing, she will have defied astronomical odds and had a very psychologically disordered captor. The mixture of killing 2 to gather up one and abscond with her ( or him) and keep the youngster alive is extremely disordered. One last thought- Jayme is on the cusp of having an adult female body vs. a more petite and child- like body. IF the perp. wanted a child-like victim, what then will happen when she grows up normally while in his capture? The only good hope I see if she's still alive is for more facts to be released so people in the area have more to go on, to look for, to recall seeing at the Wal- Mart or the IHOP recently, or while there, like Shasta's case.
