I really firmly believe that all signs point to DS successfully reaching her apartment complex on Friday, and thing going wrong during the short trip from her locked vehicle, to the front door of her apartment. Every other theory has too many variables, stupidity, and room for error, especially considering the abduction was this clean and had this few witnesses.
My theory is this: Knowing where DS lived (a security guard would have this info about people in the building...its probably in a company directory), and knowing where she parks (some VERY minimal stalking would attain this information..), that the perp was waiting at her apartment, having planned the abduction. He was waiting at the location, and the fact that DS was perhaps 30 minutes early is irrelevant, stuff happens and having thoroughly planned this out he was potentially waiting there even a couple hours early. He probably parks in spot right next to her usual spot (remember open parking lot, no assigned spots). DS weights 125 pounds and FG is a former multi-sport athlete, workout buff, and youth baseball coach. Once her car is parked next to his car, and she gets out on drivers side door, thats a nice little Cocoon of space/privacy where FG makes the grab, holds up at gunpoint, subdues, whatever...and Frankly with the Sun close to down, I don't think a lightning quick scuffle (strong/athletic male on small/petite female in a poorly lit parking lot) would be likely to draw any witnesses, I really don't. It would be hard to see a lot of things in that parking lot, let alone a 2 second tackle between cars followed by a quick departure.
As far as the search of FG's house, I don't think that has ANYTHING to do with that location necessarily being the place DS was taken. The crucial aspect of the house is that our #1 person of interest lives there. He brushes his teeth there, showers there, throws random shirts on the ground there, maybe keeps whatever weapons he owns there, his computer is there, dirt falls off his shoes there, etc etc. I really think the key to searching the house is that maybe he carried something with him back home after what happened. A small strand of hair on his jacket. A barely noticeable spec of blood on his boot. A vague scent of DS perfume in his car (that they towed apparently, right?)
I think that explains the lack of huge excitement from family and LE at the searches of FG's house. I think when they searched it the first time weeks ago, it was mostly clean..and they might be true this time as well. A thoughtful attacked would have gotten rid of every piece of clothing on his body, destroyed them, showered and/or washed himself throughly at another location, and went home (theoretically) without a trace. New clothes, etc etc. So I think while they have STRONG reason to believe FG is their guy (cell phone histories, potential surveillance, potential witness information, etc etc)...they might be lacking solid proof. Just because FG was seen at her apartment complex, or his phone placed him in that area, and thats all highly suspicious to all of us...they might know full well its not going to get the job done and convict him...so searching the house is a hail mary praying that a mistake was made that would allow DNA to do its job. Where that leaves us is that they're big on FG being the guy based on great circumstantial evidence...but they desperately need any kind of physical, foolproof evidence to put the nail in the case.
