Hi, Nobodyzgirl, you cover a lot of interesting ground here. With the washing question, my thought was that Jodi washed and dried the sheets (which probably to a woman's standards were gross) earlier, perhaps while Travis was checking his emails or preparing for the phone conference that he didn't live to participate in.
If Jodi was using the camera as a relaxing ploy before she shot Travis, she might have dropped it on the floor after she produced the gun. It seems that she tried to clean up the bathroom scene at least somewhat. Perhaps she just scooped up the camera accidentally or half consciously when she was trying to dispose of bloodied clothes or towels.
It occurs to me that people claimed that Jodi snooped on Travis. If that's true, it's possible that a message or messages on his cell phone, perhaps from his trip date, ignited her fuse and changed a stopover with benefits into a killing field.
