Heard about this on local talk radio, authorities still trying to find a match with current reports of missing persons. They went on to report what may be of most concern is what appears to be remnants of restraints on her wrist(s) which if true would lead one to think she had just escaped captivity, her kidnapper, etc.
I'd be very leery of opening my door to someone at 3:20 AM, she could be the bait and some Manson-wannabe could be hiding in the shadows.
