I've been wondering where she went missing from, too. It would help a search to pin down a starting point. Was it her parents' house?
1. Someone brought her mom's car back to the house. Since she was driving it, it makes sense that she brought it back.
2. Passenger seat in her mom's car was pushed back but that doesn't mean the person came back with her. It could've been someone she was with earlier in the day.
3. If the person did come back with her, she was supposedly texting her friend at 2 a.m. as if she was alone (she didn't mention anyone was there), saying she was going to lay down.
4. What if the texting info was accurate and she really was going to sleep at her parents' house? What if the person who came back with her - or a person who borrowed her car and brought it back after she'd gone to bed - decided in an altered state that they'd take the tapestry (or accidentally knocked it and broke it)? They could've tried to do this without letting her know (maybe she was really sleeping) and she found out and it caused an argument. If she knew it's age and that it was a grandparent's from WWII, she probably knew that her parents would be upset if anything happened to it.
Or, she could've brought the car back earlier, switched to her car and went back out. If so, how do you find the last location without phone data or a sighting? Would she leave lights and TV on if planning to be out for several hours? I don't think cats appreciate TV. At least mine doesn't.
