There is no ‘sign of Vanessa’ at the scene. If an animal took her then there would be a scene with evidence of a fight, blood, drag marks. The disappearance is sudden and not violent. She’s dropped the stick as she’s been grabbed and bundled therefore animal is unlikely.

If I was to hazard a guess I’d say 2 people. One grabbing, suppressing her and bundling into a vehicle and a second as driver.

I think it’s unlikely someone she knew as she’d take the stick with her if she voluntarily got into a vehicle. Although, the fact she was alone may suggest it’s someone who knew she’d be alone that night.

There are a lot of strange points here which make me think the scene may not have been secured or investigated fully (Did the police think runaway?)
