Thanks for the links maggief. After scrollling thru Taylors's blog (referenced in one of those links) I can't help but think of Kristine Johnson. This case unfortunately sounds eerily similar.
Kristine was also a blogger and posted on a messageboard, went missing after she visited a "photographer". Two weeks later her car was found. Two days after that her body was found.
