A few things I disagree with,
as for transferring pics neither camera used a secure digital media, in fact both cameras used different media. The Sony would have used MSP or MSPD memory stick pro and the d on the 2nd one is for duo, The Olympus used an XD card like Fuji, both makers are fond of the XD media or Extreme Digital. She is not that smart to do all the transferring but yet leave the media card, purely stupid.
If she was on his laptop at 4 am, why not access little boy *advertiser censored* sites, what was accessed if it was her did not help any so that is doubtful IMO
and last but not least, Jodi planned carefully. One does not leave a paper trail a mile long for a premeditated murder.
