I think it is just a sweet way to "bump" the thread. We all ask questions like that... Simply rhetorical questions. So combining a rhetorical question with needed thread bump makes posts like that.... Along with that, it maybe read by a missing person "googling" their name (like that Florida girl who found her WS thread and went to police station).... Or it could be read by the person responsible for them missing and play on their conscience...
I wish more would be done on this case. I appreciate it being bumped as it saddens me to see it die away. Lisa is somewhere. This case needs more attention than any of the cases heavy in the media...
So, Lisa... Where are you??
