There are several posts in Jesse G. thread ( which is now closed by the mods) but there is Renae that claims she saw Caylee. I am not sure of all the details but she went to the FBI and LE about this, I think she also spoke directly to CA about this as well.
I find everything really odd, especially seeing Caylee in I believe it was Georgia. Jesse G moved to Athens, I found that there is another Grund member in Athens, Sonja. Perhaps his sister? Isn't it just a little funny that Casey doesn't seem concerned at all, Jesse quit the police department, Casey called his on the 16th, there were airport pings on the 17th, and now there is someone that claims she is certain she saw Caylee alive? Could by chance Casey has been involved or witnessed another death? And called Jesse to help her hide her daughter? Also because Jesse thought he was the dad for the first 10 months, he loves that little girl and I am sure he would do anything to protect her as well. If I were involved in anything where my childs life had been threatened, I would in a heartbeat hide my child and not say a word to LE in attempts to make it appear my child was not around. Especially if someone plans to harm my child. I would do exactly what Casey is doing by not speaking to LE in attempts to allow my child to be out of harms way, in the same way I would take a bullet for my children.
This may be far fetched. But I am trying really hard to see different aspects to this case. Something's up, there doesn't seem to be evidence that she killed her child and unless she really is a cold blooded killer, she doesn't seem the least concerned about the whereabouts of her child or her well being. I think because Casey knows her child is alive and she is in fact ok.
JMO, feel free to debate it.
