I used to live in Fresno, and I am familiar with this shopping center. At the time of her disappearance, I remember that it was reported that there was a shopping bag from Marshall's (I think it was Marshall's) in the car with items that she had just purchased that day. Marshall's is in the same shopping center.
I wonder if she shopped, went to her car, put her purse and shopping bag in the car, but then noticed that someone she knew pulled up behind, or next to her in the lot. I wonder if she then shut the door to the car and started to speak with someone (I do this to keep that annoying buzzing sound from going off when the door is opened-if my keys are in the ignition), then was grabbed?
I also noticed that her husband's cell phone was traced to Reedley. Reedley is not at all far from the foothills of the Sierras. It has a lot of open land and forested areas nearby. It's also nowhere near Kerman, where he worked. I wonder why he was in Reedley?
I'm glad to see there's a thread for Sandra. I've thought of this case often over the years, and I've always felt so sad for her daughters (she had two adult daughters).
