I can't stay away. My mind is racing over 100mph on this case. I want to post while thoughts are fresh in my mind.
Okay (taking a different tact now).....
Let's look at the possibility something DID, in fact, happen to Adrienne at the party!
What if, mind you these are only "ifs", after her fight with the boyfriend and she came back to the party, she was so upset she continued drinking and then she had a drug overdose.
Remember I am only pretending here....I don't know anything happened (if it did)....
So maybe only a couple of people, maybe two or three even, knew anything was wrong. And no one wanted to be responsible so they decided to take Adrienne somewhere else and leave her body and hatched up the story that she had left again to go back to her boyfriend's place.
So they put her body in her car. It wouldn't be difficult to get her out as tiny as she was. The party, with all those people crammed into a small apartment, was probably pretty chaotic.
And then as they were driving, intoxicated, they hit the median on Rio Salada. There were two of them in the car (as the 911 caller thought) and so they sped away because they had a body in the car to dispose of. They went to the most remote place they could find that the car would make it to and then they drug her body as far away as possible and covered it up with brush or whatever they could find.
They had her cell phone and to throw off the scent they made 11 phone calls to the boyfriend and called a cab to meet them at the AM/PM. They did this just as a red herring. And it was a girl who did the calling, which is why the cab driver and dispatcher think it was Adrienne. A female voice.
Then, to cast further suspicion away from themselves, they sent one final text to the boyfriend saying she was "coming over".
Then they went back to the party. Because they had the wreck on the way to dispose of the body and they knew if the keys were not found that the area would be searched more quickly and the body found, they took the keys back and put them in her room. They never took her wallet at all. And the story about her packing a large purse was never true. They made it all up.
Has LE thoroughly searched the area where Adrienne's vehicle was abandoned.
Okay....all speculation. Sheer speculation.
All in my very humble and confused (grasping at straws) imagination.
