Interesting little bit of info in this update for those thinking about the stepfather being involved..

For this to be true they don't just need her entering the mall, they need proof he left the mall and returned alone, otherwise all they have is proof she entered the mall - and it would need to show she had her luggage with her. For me, the luggage ending up in his living zone and "awareness space" is important. I've also noticed VA police in particular, over many cases, to be very elusive and experts at misinformation. All for good reason, of course. A few possible scenarios come to mind:
1. He waited for her and the incident happened after the mall trip
2. she left her bag in the car but had her phone, he left with it, she ends up stranded . He dumps her stuff either out of derision or after she goes missing because he thinks it will incriminate him. (If he touched her bag at all it should have fingerprints)
3. He dropped her off as stated, she entered with her bag, and something happened in the metro or another unpopulated area
4. She met someone there and staged her disappearance, dumping her stuff all the way back in Spotsy (to purposely deflect on him or frame him or because it is on the way to her mom's?) or met someone she knew who is from that area.
While stepdad is not a suspect according to Stephen Tschida's tweet (which is not a quote from LE and is not repeated in the article) , he is the last to see her so is a person of interest no matter what, so don't think they aren't looking at him. With regards to WS TOS we should still wait for an official statement before discussing his particulars openly or judging him in any way.
