My husband is a physician, and he said that a body will start to decompose within a 24 hour time frame. Caylee's body was probably already starting to decompose in Casey's trunk, hence the stain and hair. They reported that the hair was from a decomposing body. My thoughts are to look for a suitcase of some kind. Remember that Casey packed up all her stuff and left her parents home after an argument. A roller bag would be easier to move, and you could put in something to weigh it down if you wanted to get rid of it in water. Some of Caylee's liquified tissue and hair fell off when Casey put her into something, a suitcase, a trash bag, ect. I can't help thinking about the dumpsters at the Amscot store. A trash bag would just end up in the dump. Maybe she had to wait to put her in the dumpster until trash day. You really don't want a body stinking up the trash too much. Less chance to notice an odor after the store closed on trash day or the evening before.
Forgive me for being graphic, I'm trying to think like Casey.
The suitcase would work for water, as mentioned above. She could have dumped her off of a bridge, but she could get caught, unless it was one that didn't have much traffic. The 417 bridge over Lake Jessup is right over LOTS of water, and 417 isn't traveled much in the wee hours of the night. I wonder if they have taken cadavor dogs over this bridge to check for decomp smells??? She could have pulled over the side of the road, like she had a flat when she did not see cars in either direction, and then tossed the suitcase over the bridge pretty quickly. If someone stopped to help, she could say she got sick or something. BUT, I could see this happening without anyone stopping. Too many people killed pulling over to help a supposed stranded motorist in Florida, and elsewhere...remember Bill Cosby's son??? If she put one of the imfamous "pavers" from the backyard into the suitcase, I don't think it would take long to sink. Anyone in Florida want to test my theory???
