This is what I'm thinking. Three options.
1) into another vehicle. If there's a camera, which there clearly is, they'd be able to see that someone else stopped and left again between her and the police.
2) ran across 459 and disappeared on the other side. Very hard to do safely judging from the video, and would be on camera.
3) went into the woods. Is either still there or went into the neighborhood on the other side. Why go into the woods? Either you are following someone, you are fleeing, or you are forced. From the loss of the wig and hat, moo is that it's one of the second two. A struggle and she escapes briefly and runs that way, or a weapon is on her and she complies. Who forced her or who did she run from? Someone who was already there, since there's no other car arriving. How did they get there? They came from the woods.
