I would assume there is a lid on information released, for reasons of privacy, not to tip LE's hand, etc. Here in Florida it seems to be a bit different it seems and much is made public, often to help in leads, tips, etc. I woudl think too, honestly if they were looking for TWO people they would say TWO people. It would be self defeating to think she was attacked by two people but then say well we need tips about ONE person. Look at the Eve Carson case. It started out with one person... then they figured out the second person was in the car photograph, and they started looking for him too.
Some of the more sordid details I have found have come from less than reputable sources online. So I do not trust them. They all have the same wordage, with slightly different twists... "my friend works in the coroner's office and said... my friend is and EMT and said... my friend worked at the hospital and said..." But then what they say is identical, word for word. There may be tiny germs of truth, but I dont think you can really sort things out. These sites imply there is some sort of conspiracy. I don't really buy that. I think just certain info has not been released for privacy or investigative reasons, at least when it comes to ethnicity of the attacker(s??). There are plenty of other high profile crimes (Eve Carson case again) where LE did not keep the race of the suspect secret. Im not a big conspiracy theorist. What happened to me personally was nothing mysterious or complicated. It was too simple really. So that is waht i try to think about here.
I still have a feeling it is some sort of stalker/obsessed person, or maybe drug related (someone flipped out on PCP or something). It takes a lot of rage to do something like this. Emotion. A gang hit wouldn't be so gruesome usually.
I would look maybe at where the gas station was located where her card was used. People (unless they are travelling long distances) tend to buy gas at local stations near their house, on their way to/from work, etc. Maybe the attacker lives/works/passes by that area frequently. I don't know the layout of Little Rock, but say Anne lived in the middle of town, it would be odd for someone that lived on the East side, to drive to her house, commit the crime, drive 20 mins across town to the West to the Gas station, then drive back across town to their home on the East side. If the Gas station was near an interestate, then maybe they were leaving town. But then would a stalker come from afar? Anne was seemingly very popular locally, but would she have had a stalker from some distance away? Her role in W was miniscule, and the movie had just come out at the time of the crime so I don't see anything there but coincidence. So unless the attack was totally random and she was in the wrong place at the wrong time, I feel somehow it was someone in her general area (Little Rock).
I can see some strung out teenager crawling through a pet door or something. And they could freak out and do such a horrible, rage filled crime. But would they have the sense to take weapons away, maybe hide things or not leave many clues, then seeminly get into a car and drive across town for some gas?
Please forgive any bad typing.
