if there were banded animal hairs (yes AH confuses me too, maybe we should stick to "fur"!) on the momma doll I would think most likely from the A's tabby cat, as my tabby has banded hairs like that.
Animal hairs on the pizza box, that's a puzzle..... (unless the tabby jumped into the trunk at some point when it was open due to the smell then got around the pizza box....) Or if it was wild animal hairs on the pizza box I guess maybe if the pizza box was grabbed from an outdoor trashcan or something to place in the trunk as a smell excuse or something... No, I don't remember any mention of a pet at the Sutton Pl apartment, wonder if friends or Clint or Nate's girlfriends came by there with pets or anything. Hmm.
I remember wondering early in the case if anyone might have put a dead animal in Casey's trunk to terrorize her, i.e. a scenario in which someone she was in trouble with had taken Caylee as security to get money back or who knows what, I don't know why that thought even came to mind but it was one scenario that did come to mind originally, this was long before talk of animal hairs actually being in the trunk. Another scenario that came to mind originally was what if she didn't know about Caylee having been in the trunk, thought Caylee was with some associate, and was going on in a clueless manner about the smell in her car to people she knew (one of them being the perp), what if the perp then put a dead squirrel under or in her car or something to make her think that was it. (Again, just early scenarios.) I agree I also can't rule out Casey placing roadkill there herself if she's the perp. If squirrrel or wild animal hairs got transferred to the trunk in some innocent manner like on a tire or something like that (which could certainly happen), it would just be very coincidental considering her squirrel story... OK, now I want (need) to go back and read about these fur hairs again. I need to brush up (that awful pun was not intended LOL!).
