...not sure it'll help, but, after re-reading above...here's another angle.
What they are doing is effectively trying to reverse-engineer what was actually in the trunk. Its a bit like tasting a cake and determining the recipe from your keenly developed sense of taste. Add to that what you can learn from cake recipes. From most recipes you have a good idea of the relative amounts of each different kind of common ingredient (e.g. 2x as much flour as sugar and 1000x as much flour as vanillin, etc.) should be in the cake. If you tasted a cake and thought, "Whoa! Waaaay too much vanillin!" well, then, you might think someone (a) added too much, or (b) spilled the vanillin bottle into the batter
Add a little sleuthin' and learn that on the day after the cake was baked you found a receipt for a new bottle of vanillin...and AHA!! You think you've solved it. Right? The baker put in too much! You knew it!!
Then you learn the truth. The baker forgot to stir the batter, and it just so happens that the bite you got contained 100% of the vanillin that was in the cake!!
Moral of the story...we make assumptions when we draw conclusions. Some assumptions are good ones...and some...well...not so much.
What do we know?
- We know that chloroform is produced from anaerobic HDE
- We know an HDE took place in Casey's trunk
- We know chloroform was detected in Casey's trunk & not in a similar one w/o a HDE
- We know Casey searched how to make chloroform March '08
Now...IMHO the first three items in that list are repeatable...IOW...do the same thing 100 times and you're likely to get the same results ~100 times.
The last thing in that list...well...that's where you make an assumption on how much initiative
you think Casey is capable of. My :twocents: I can't think of one other example that shows Casey demonstrated the kinda effort it would've taken to either obtain or produce chloroform. Make your own assumption, but, I can't get from Casey-read-about-it TO Casey-
did-something-about-it.
BTW...in the case of the Pontiac trunk...its more like the scientists have to sort out from everything we think might've been in the
pantry...if it was too much vanillin that screwed up the cake. That's a toughie fershure.
