I hadn't noticed before, but watching the video where they think the abduction might have occurred, it struck me the bend in the road would conceal a stopped vehicle waiting ahead for a jogger. She had a clear view of the road ahead for most of the jog, except for that curve at 385th. If he had been tailing her and he knew the road, he could speed up past her, pull over after the curve and wait for her to pass by. If the corn was high enough too, he could possible have pulled into a dirt driveway between cornrows and waited for her.
Also, man its stupid ballsy because of it being broad daylight and there being a houses around.
JMOO, the pic is just something I threw together. It could have even been a bit further along the road where it was more deserted.
