Macing through a crack in the window was also logically inconsistent with the alleged purpose of kidnapping.
It was an assault, plain and simple.
She had been stalking Shipman for two months. Surely not just to douse her with pepper spray?
Lets go back a few steps.
Victim was supposed to leave for the car park earlier except she was delayed because her luggage was delayed.
Had her luggage not been delayed, she would probably have been on the bus with other potential witnesses who may have had their car parked within earshot of Shipman's.
It doesn't make complete sense to me that Nowak, who had planned so much, intended to leave it up to chance that a forceable kidnapping would go unheard and unnoticed in a parking lot where numerous people may be milling about. And keep in mind that such lots often have video surveilance and security details.
There is something important missing to this story and none of us have the answers.
