Ok - here ya go - please remember this is my crazy sci-fi, CSI lovin' hubby. But I have to say - even though it does sound like an episode of Law and Order - it could be somewhat credible. . . .
It is his personal opinion that Zanny does exist - or did. Zanny was a mule - someone who transports shipments of drugs. Casey dropped Caylee with her around June 21. Zanny calls Casey and tells her she needs to "make a run" and has left Caylee with a "mutual friend". Casey knows this "mutual friend" and is alright with it. Zanny goes on to tell her that if Casey picks her up from bus station or wherever when she gets back, Zanny will give her a "taste" or maybe even more from the shipment and they can go pick up Caylee. Zanny is only going to be gone maybe 10 - 12 hours so Casey says sure. Casey picks up Zanny when she gets back - June 22. Being the coniving, scheming witch she is, Casey figures she'll just make Zanny "disappear". That way she can keep the shipment (big $$$$) and then go get Caylee. Casey kills Zanny (or Zanny OD's) - goes to GM and GF house remember they weren't home for those couple of days - finds out she can't really bury a body there. Backs up the car, breaks in the shed, gets the gas cans, puts Zanny in the trunk. She goes somewhere and gets rid of Zanny. Now to go pickup Caylee. When she gets to the "mutual friend" she finds out that "friend" is the trafficker - the one Zanny was to deliver to (which was unbeknownst to Casey). Friend tells Casey - no Zanny - you don't get Caylee. Tells her that until Zanny or shipment is produced - Caylee is collateral. Casey is now reeling. She hides the shipment or has already sold it or maybe Zanny sold most of it. So now what? What better way to find Zanny than to have LE looking for her. "Mutual friend" doesn't care that LE is looking for her, but is pissed because he/she has Caylee and has to keep her hidden now. Casey wants to talk to the Feds - tell them this sordid, twisted tale, because after all she hasn't done anything - she'll play it off to the Feds that Zanny OD'd or someone else ambushed them and killed Zanny and took the drugs. She is just an innocent player that got "caught up in all this". Who did Casey go with to Universal to find this "mutual friend"? And was that where she found out she wasn't getting Caylee back? There has to be some reason why LE hasn't dropped the bomb. They have certainly had enough time to nail Casey's arse to the wall if the logical story of her killing Casey is true. Susan Smith cracked in 9 days and only because they were closing in on her. Casey has been sitting in jail for almost 2 weeks - 14 days and is sticking to this convoluted story of hers. If just some - one or two tidbits - of what Casey has been saying is checking out - LE has to know something is up. Or maybe they have ID'd the stain and it isn't Caylee. Still doesn't explain why LE isn't searching though or they could be searching just in the background without letting on that's what they are doing.
Now is that a story or what? At least hubby is happy and has gone away. I keep telling him he should be a writer. He does seem to explain all that we know to have happened.
