Not much has been released to the public about Marcia's last known whereabouts except for what's been in the media and what was said in the press conference. Investigators are trying to trace her movements the month before she died. All we know is that the family has indicated she could have been in Pittsburgh, PA and Louisville, KY.
In the beginning, we got some unofficial information from her family when they posted a few things on BG's facebook page. The posts were removed when her poor family started getting harassed by people who felt the need to call them and yell at them for not reporting her. I'm afraid we'll probably never know now, thanks to those folks.
