This is theory I saw posted on another website. I thought it could very well be a possibility.?.
"I was listening to the tapes of Casey talking to investigators. After listening to a few more, I think I may have part of the answer we are looking for. Whenever we hear Casey talking to investigators, they talk about her giving wrong adresses, going to places she had never been to before, asking for people who aren't there anymore, etc. After listening to a few more, well I thought of something. Let's put it this way. I had a guy I dated back in college. He would get drunk constantly. To the point of nearly blacking out, but not quite. His stories would sound crazy in the morning, he went here, he met Bryan Adams, than we would meet the guy who sort of looked a little bit like him and whose name was Bryant Ada. Anyway, the point is the stuff that would come back to him would be slightly off. I believe now, that Casey, got so drunk, or drugged out, (not sure which), that she doesn't REMEMBER exactly what happened. I think she doesn't believe she would ever harm her child, and she is leading the police by what little she remembers, or thinks she does. She may think she went to her old place of work, and perhaps thinks she may have left Caylee there with someone, IE - When she told detectives that the reason for bringing them to the former place of employment was to show the picture of Caylee around. She says, "I'm running in circles because I don't know what else to do". Why? Most likely because she can't remember what happened. She remembers bits and pieces of what happened, and some of it, "Juliet Lewis knew what happened", is made to be bigger in her mind, and in actuality may have been someone who resembled Juliet Lewis and whose name was June Lawrence or something and is someone she met somewhere that night. Perhaps she went by the nursing home, and it got stuck in her drunken mind and she thought it might have had something to do with where Caylee is now. Perhaps she ran into a person or two whom she worked with at Universal so many years ago, and went by the building. Now she thinks she went inside and so and so were still working there. It's not a far stretch when someone is drunk or drugged. What happened to her daughter? That I don't know. But if her mother was that drunk or drugged, anything could have happened. And her body could be anywhere. Only she can retrace her steps, and she was trying, I think, to do this with police. But she ran out of time. The cops ran out of patience and honestly believed she was just trying to stonewall them. What if she wasn't? What if she was trying to retrace everything she did that night? What if she was doing her best to try and find her daughter? And she needed an excuse for the cops to take her to these places? You see, the way memories work, we all do this, where's the last place you remember having it? And we go to that place. And than we think ok, it's not here, where did I go after here? And sometimes it triggers another memory. And another. And another until we trace it to the place we left it. Just a thought."
But lets be clear! I am in no way making any kind of excuse for casey anthony or anything bad she may have done to her daughter. I just posted this person theory because I thought it was interesting. If casey did do anything bad to Caylee may justice be served! It was just another way of looking at things.
