If you have a queasy stomach, PLEASE DO NOT READ THIS.
I really hate to be morbid, but the documents that were released last night leave little wiggle room.
The towyard manager said that when he opened the trunk, flies flew out and there were maggots inside.
A trunk is a sealed environment. Flies will not attempt to enter something like a closed, sealed trunk to lay eggs on a pizza box. Even if that pizza box had pizza in it, it just isn't going to happen. Think about the times you've left a half-eaten hamburger on the floorboard of your car. (I'm guilty of this...commuting to work, high-stress job, forgot about the half Big Mac I left in the car for a week.) Think about the Taco Bell bag you left on the back seat...people with kids will admit that we've occasionally left food in the car and forgotten to remove it.
Sometime in their life cycle, those flies entered that trunk with Caylee's body.
I believe that Caylee's body was stored outside somewhere...somewhere that flies could have laid eggs on the corpse. It could have been stored there for as brief as several hours or as long as several days.
Casey worried that the body would be found wherever she left it. Or maybe she knew the dumpster-emptying schedule for the waste company in Orlando. At any rate, she went back to remove the body from the place she had left it, and she put it in her trunk.
Possibly, the corpse stayed in the trunk from the time she retrieved it until the second time she dumped it. The second dumping of the corpse could have been done on the evening of the 26th, early AM hours of the 27th (the time window when her car was left at Amscot, parked by the dumpster).
When she loaded the decomposing corpse into the trunk the second time, fluids leaked out. Clumps of hair fell out. Possibly decomposing flesh detached from the body. Decomposing flesh with maggots already hatching.
When she removed the body from her trunk (to possibly place in the Amscot dumpster), some of those pieces of flesh with maggots were left behind, possibly on the white garbage bag in the trunk.
This would explain why there were flies and maggots in the trunk when the towyard manager opened it.
Let's look at a generalized life cycle of the species of flies that assists in decomposition of a body (if we knew the exact species, we could be less generalized in the life cycle):
From egg to larva (maggot) is 2-5 days. Until day 5, the larvae are feeding on the body.
The larvae move away from the body to become pupae, and are adult flies on day 19 or 20. Adult flies feed on body fluids, mate immediately after emergence, and lay eggs within two days of emergence...and the cycle begins again.
So, to summarize this:
Day 1 - eggs laid.
Day 2 - eggs hatch.
Day 2 to 5 - larvae move into and around the body, feeding.
Day 6 to 19 - pupa stage, no feeding on corpse, mature flies will emerge from the hard case.
Day 20 - adult fly emerges, feeds.
Day 22 - adult fly lays eggs on corpse.
Therefore, the flies that were found in the trunk were second generation flies, as were the maggots, because the car sat sealed at the towyard for 16 days. The second generation had already emerged and begun laying eggs, which had hatched into maggot staged larvae.
I can't wait to see what a forensic entomologist will reveal about this case. I think that the transport of the corpse can be nailed down to within a couple of days using the life cycle of the flies that flew out of the trunk on July 16th.
