One of my observations about the area where Adrienne was thought to be walking to meet the cab at the AM/PM. It is .3 miles from her apartment to that location. I clocked it in my car the other night.
"Rumor" has it that she was last seen near the corner of Ash and Hardy street at approximately 4:30 am and was walking in the direction of University.
If this is accurate, she would have been at the store in about 5 minutes, walking at a normal pace. That would have put her there at 4:35. This strikes me as interesting because the last activity reported on her cell phone was a text to her BF at 4:47 saying "I'm coming over." And the final 3 calls interacting with the cab company, came at 5:04, 5:05 and 5:06 am (respectively).
Based on this it sounds to me like she either caught the bus, which there is a stop located just in front of O'Reilly's facing University St., got in a different cab from the one initially dispatched, or maybe she might have known someone who lived in one of the many many many apartments that lace both sides of the street in between Ash and University.
It is not out of the realm of possibility that someone could have snatched her up on the street, but this seems highly unlikely to me. If someone were to do that they would be taking an incredible chance of being seen. There are just too many apartments located up and down that street for that to be a viable scenario in my mind.
To me this almost rules out a 'random' abductor. It would have had to be very planned IMO, by someone who was in the business of abducting your girls or who had a lot of interaction with them and that she trusted.
JMO after having been there and observed the area.
