Check out the "Anthony's Computer Forensics" thread, starting with this post by JWG [ame="http://www.websleuths.com/forums/showpost.php?p=8223072&postcount=1085"]http://www.websleuths.com/forums/showpost.php?p=8223072&postcount=1085[/ame] for complete decimation of Jose's theory about George's computer activity.
As I understand it (I haven't read the "book"), his theory is that, at 1:50 pm on June 16, George (having just recently killed and/or molested and/or discovered Caylee in the pool) searched "fool-proof suffication" [sic] because he wanted to kill himself. His "evidence" that this was George was: (1) the search was right after an AIM login and "Casey didn't have AIM," (2) George is the poor speller in the family, and (3) the search was followed up by some "gardening" searches, which George likes and Casey doesn't.
The truth: The search was done at 2:50 pm, not at 1:50 pm--so was after George left for work. Also, leaving aside the ridiculousness of wanting to kill yourself through suffocation for about 2 minutes and then running off to work instead: (1) the AIM login URL strongly indicates that this was Casey's login, not George's--see JWG's analysis for more detail--and the search was interrupted by views of MySpace and Facebook as well (which George didn't have in case you're wondering, JB), (2) yes, JB, Casey did have an AIM account (although so did George)--if you had read the discovery *cough cough* you might have noticed all the released AIM transcripts between Casey and her friends, (3) um, Casey can't spell, JB--"chloraform" anyone? how about "begining"? or "iorn"? wait, no, that was you, (4) the "gardening search" was a click of 11 or 12 seconds on a website that was one of the search results from the "fool-proof suffication" search.
