I was wondering this too.
Three years ago we had a thread to discuss JH and mental illness:
http://www.websleuths.com/forums/showthread.php?180649-Armchair-Psych-Profile-and-Treatment One of the things I remember someone asking was about effect of living in an apartment with those fumes of gasoline and whether that could have had an impact on his mental state. I think they testified that he had used air fresheners to mask the smell. I wonder how long those carpets were saturated.
Also, how do you guys find this Trial Discussion Thread? Before, the movie theater shooting page used to be linked to the main Websleuths page under Trials in the News, with all the related discussions. Now, I can't seem to find this Trial one without googling and scrolling through threads 1, 2, and 3....There's probably an easier way. I'd bookmark but my bookmarks are so long....
