SophieRose:
I'm so happy to have someone on this thread with me after it being quiet for so long! Thank you!
I looked at an aerial map with the starting point of Diane's house on Rainbow Drive in San Jose. You are thinking they went straight up Saratoga road/hwy 9. Yes, that makes the most sense, although I will say that's a bit of a drive. There was methodology to picking that location aside from the fact it was/is mountainous and remote.
And yes, I looked at the map for Freedom, CA. I've lived here my whole life and never knew there was such a little town. It's history is quite interesting. Even today, folks that live up in the SC or LG mountains are considered "mountain folk", and to be perfectly blunt either hippies or "herbalists". I know that is a general statement, so please, no offense. Diane certainly did not seem to fit that profile, at all. So the fact they lived there seems incongruent.
So back to the drive to the mountain area. This just has to be a "pay back" of some sort. But what?!?
She must have been in a van and concealed, and there must have been more than one person, maybe three.
One driving, one holding the baby, and one detaining Diane. At least two.
