I really feel that she got into a car with someone she knows. Or, if she was taken by force, it seems likely that it would take 2 people. I imagine she was carrying her phone and had her purse on her shoulder. If someone forced her into the car or truck she potentially would have dropped both items.
Have you guys looked at the street she lives on up close? It only has a handful of homes on it. If she moved there in October the person may have gotten up the courage recently to do something. That person may have befriended her as well, if they are a neighbor or someone she sees often around the neighborhood. Someone could take that route to work and has been watching her walk to the bus stop everyday. But I do think it is someone she knows. Also because the dogs could not track her past the driveway. The houses are pretty spread out and there is really nothing else around, so I'm not surprised that nobody saw anything.
"Klaas said that after reviewing the evidence, he believes Sierra was likely abducted on the street where she lives."
"Whatever happened to Sierra happened on that block," he said.
