Our great great late Foxfire emphasized any predator who would do something like this would have a moment in time of weakness, that would be at the crux of their actions, and the crime would be the moment of elation.
Reflecting on that, I wondered if the space around the high school on the edges of town, around Mollies house, may have been the initial draw, then Mollie ending her jog on the other edge of town. Less exposure within town.
This perp could be someone who started acting out in high school, I don't mean in Brooklyn necessarily.
But then why in Summer? Fewer eyes in the evening maybe?
